I've asked quite a bit on here, but haven't really given much feedback. Well this is the thread for that. I've been working on the quad for a few months now, but money is tight so I'm getting parts as I get the money. The overview:

'01 300ex frame
'88 RM250 powervalve motor
400ex suspension
400ex plastic

That's pretty much where I stand now. I'm waiting on my '88 RM250 bottom end to come in. It was supposed to have been shipped Wednesday. I'm also waiting on some 450R bars from brandon34r, a set of 400ex wheels from 200xer, and a parts lot from ebay.

Here's the bottom end -
http://i19.ebayimg.com/03/i/000/77/90/9f5b_1.JPG

The parts lot has footpegs, handlebar clamps, swingarm pivot bolt, and a few other parts.

I'm sure you guys realize by now this is going to be a budget build. I figured I could build a pretty nice quad like I wanted cheaper than buying a quad and fixing that way. So far with everything listed in this thread I have $394. Let me know what you guys think.

01-05-2007, 06:18 PM
Also when the bottom end comes in I'm going to get it mocked up so I can get the frame fully painted. Then I'm going to get the frame in rolling form. Then rebuilding the motor. Lastly will be the plastics and left over stuff.



What do you guys think so far?

The 88rm250 had a killer motor that year.Try and look for a pipe from a 86 or 87 rm 250,it will be a bit easier to modify to fit your frame than the "lowboy" style on the newer ones.i used to own a 87 rm250 myself;)

Thanks for the tip. I was going to go CR250 after talking to you about it, but then almost got screwed over on that one. So I found this on for a pretty good deal. I'm praying it will be here tommorrow, so I can get it fabbed up and get the frame fully painted.

I got my parts lot in, but still no motor. Also I made a mistake I said earlier the paint was metalspeck, but it's actually metalcast.

Steering stem with handlbar clamps.

What's left of the parts lot, excluding the handlebar clamps and bolts. I have them soaking in laqcuer thinner to get all the old paint off. I'll probably leave it bare aluminum.

I sent money off saturday to carlock #33 for his '05 450R swingarm. Hopefully it will be here by the end of the week or early next week.

My bottom end is coming in today. I've been waiting by the door all day. I'm going my gf's house a little later and was planning on getting it mocked up before, but it looks like I'm going to have to wait until I get back to do it.

I got the bottom end in. The side case was off of it and the kickstart assembly and gear for the powervalve was out of it. I think I got everything together right, but there was a bearing left over. I'm going to take it back apart and rebuild it after I get it mocked back up. I have run into a few things though. First if I center the pivot bolt mount up on the pivot bolt the sprocket shaft is sitting too far in for the chain guide. Can I make a spacer for the sprocket to make it line up? Also I am only able to go through three gears. I was thinking this is a four speed. I'm uploading pics now.

This is how it looks if I line up the sprocket shaft with the chain guide. Notice how it doesn't sit center on the pivot bolt. Can I just center it up on the pivot bolt and make a spacer for the sprocket? Also how wide are the mount parts for the 450R swingarm?

I see that shifter causing you problems. You're gonna need to shift the motor about an inch to the left to get the sprockets to line up.. and that shifter is going to hit the frame.

I suppose you could clearance that gusset and reinforce that area up another way.

Put hard rubber inbetween the motor and the mounts so it will cut down on the vibrations. You can also get your crank balanced to cut down even more.

I've got the shifter slid where it just barely clears. I'll make a spacer for the sprocket to the get it to line up. It looks a lot closer than in that one pic. I'm up her at her house, but I'm going to work on it when I get home.

I got the left side front mount welded up. The brackets made for one of the bottom mounts. I'll just get a long bolt and use small steel tubes to go between the brackets and the mount. I'll probably do something similar on the other bottom mount. Here's some more pics.

Also here's a pick of how the sprocket shaft lines up now. I think it will be fine with a small spacer.

After I get everything welded and ground down on the frame it will be the same blue/purple color as the subframe portion. I'm going to do the swingarm and motor mounts black. The motor will be cleaned up after the rebuild and painted, but I still haven't decided which color. Here's the scheme I'm thinking about. I may paint the cases black and the cylinder/head something else.

Frame - blue/purple color in the pics
a-arms, swingarm, motor mounts, motor cases - black
plastic - yellow 400ex
cylinder, head - ?

The frame only looks blue in very bright light. It almost looks black normally, but has a very slight dark blue/purple tint. The closest pic to how it normally looks is at the bottom of the first page near the bottom. It's the one of the steering stem with the clamps on. It does have a tad more of a purple/dark blue tint though.

I'm going to use stock 400ex plastic because I love the 400ex plastic, but don't want to spend the cash for a custom color.

Don't worry too much. The metal is about twice as thick as the original. It also comes back to the frame and the top and is welded to the tubs. I may put a little reinforcement on top of the mount parts though.

to clear your frame.It looks like your well on your way,when you have to fab everything you would be surprised at how little you can get done in a whole afternoon in the garage...hehe thats the fun part though,you'll learn a lot.keep us posted:)

It's all good. I'm going to have to use a small spacer. I haven't got a sprocket yet to see how it sill line up, but I'm hoping it won't be any more than 3/8". I'll probably chop the shifter out and a little forward, but I want to wait until I get my left peg in so I can get it exactly how I want. Tell me about the time. I've put around 6 hours into just mocking up the motor mounts. I've got some good news on that though. I just finished up the last set of mounts. Here's some pics.

I did my best to utilize all of the stock brackets, in case I happened to change the motor and part it out at some point. The only brackets I had to get rid of are the two back ones under the pivot bolt. Anyway, I'm about to go get the motor out, weld up the inside of the mounts, and paint everything. Also I forgot, does anyone know how wide the frame mount has to be for the 450R shock linkage?

Sure is. I'm going to rebuild it though. It will also be painted. The guy said it ran when he took it out, but it will need new bearings. I asked him which specific ones, but he hasn't got back to me yet.


Also yes those are drill bits holding the mounts up. I haven't got the bolts for them yet.

Thanks for the fine comment 2muchquad:rolleyes: I hate it when people like you to try to start chit. I'm not bashing this project I was just pointing the stem out. I would think if the guy was able to mock up the engine then he wouldn't have any problem straightening out the stem. I posted so I would continue to get updates on this project not to argue.

Finished up the frame and started putting stuff back together. I know the frame looks dusty. It's where the paint got in the air, then dried and settled. It wipes right off, but I wasn't worried about it right now. I also changed my mind on the arms. I'm going to repaint them gloss black instead of flat black. Hopefully I'll have them installed tomorrow night.

looks good. you should invest in some aftermarket bars like tag or fly flex bars. it will cut down the vibration to your hands and make it a nice ride. my stering stem was so bent it would make it hard to turn and i had a welder cut the ends off and make a new one with my old but +3. its vary strong with a solid square rod in it and its a bit fater too. workes great for me but in 6'ft. ill try to get a better pic today.

If I end up having problem with the stem I'll do something about at that time, but I think it will be fine. We'll see when I get it rolling.


I got my right side arms painted early today and got them put on tonight. I also sprayed the left side ones after. I'm about to go put another coat on them. Then I'm going to lift some and maybe they'll be dry enough to put on tonight.

I'm definatly going to clean it up when I get most of it together. I figured if I detailed it now it would be just as dirty before I get it rolling anyway.

Here's some pics with both sides on. Also my 450R swingarm is supposed to be here tommorrow thanks to Carlock #33.

I know I said in the first post this is a budget based build. So I'm sure there are some people interested in what kind of money I'm laying down for this project. Well here's a complete list. The only things not mentioned are two 3/16" x 2" 36" pieces of steel, two 1lb spools of flux core welding wire, and the cans of paint; which all comes out to be roughly $60.

’02 300ex Frame - $92.63
’03 400ex a-arms/spindles – 61.50
’02 400ex steering stem – 22.49
300ex front hubs/brakes - 45
’88 RM250 bottom end – 65
400ex wheels – 70
250x parts lot – 23
’05 450R handlebars – 15
’05 450R swingarm – 45

Total: $439.62

Thanks man. It's a slow process since I'm doing it as I ge the cash. I've been trying to source a cylinder and everybody keeps wanting around $150 for ones that still need bored. It pisses me off since I could have bid a little more on one on ebay that was good and ported for less than $100. I wasn't at home when it ended and couldn't raise my bid.:grr:

sucks man keep looking on ebay and try this place like rocky mountain atv .com i didnt make it a url because sometimes they dont work when you click on it but search it on google idk if they will sell cylinders but everything they sell is the same top quality brand as all the other stores sell but for way cheaper and it will be new ill search it right now and put another post if they have one what kind of cylinder does it need to fit like the km 250 i think it was?

Hey I just thought I'd let you know that if you decide to try to straighten your steering stem, DO NOT use a torch to heat up. You will weaken the metal and it will just bend again, most disastrously(don't ask me how I know) I would reccomend you cold bend it back into shape with a shop press. IT works rather well, and doesn't fatigue the metal at all. Looks like your project is coming along nicely. What did you do about the sprocet not lining up with the chain roller? I see that when the rear engine mount is centered ont he pivot bolt, that it is off to tleft by about 1/2 an inch. You might have to modify (grind away one side) of the space in the center of the swing arm, then make a spacer on the oppsoite side to compensate. I'm not sure though, I can't really tell unless I see it in person. I made a 300ex/CR500 Hybrid myself, but I moved the engine forward so I didn't have to use a swingarm with a space in the middle of the pivot for the rear engine mount. That thing was brutally fast, but a nightmare to start and ride. It was such high compression , it always had to be pull started by another quad.

Not many updates. I just sent out money today for some 250r front shocks and a crank bearing/seal kit. I also got the cases split the other day. I'll have to mess around with it some more, since I wasn't able to get the crank out of the right side case. I think a guy is holding me most of the 450r rear parts I need, until I get paid for a job that's in my shop. I haven't heard back, so hopefully he is.

I'm running stock 300 lines. I moved the arms up and down and turned the hub and it's seems to me like everything is clearing. I may get some braided stainless lines later though.

I got my shocks in today. I thought the bearings and everything would be with it, but it doesn't have the lower bearings/bushings. I can't hardly find them anywhere either. Ahh. They're just mocked up now with longer bolts.

WOW! this is a great project I love the way it is going. I have a lot of 300ex/400ex stock parts laying around and will be willing to help out. Tell me the length and o.d. of the bushings for the shocks and I'll see if I have any or if I don't I'll see if I have the metal stock to cut you a few on my lathe. Also post a list of the stuff you need to continue.

I think the bushings should be the same size as a 400ex. I'll go measure it real quick though. Here's a list of stuff that I'll end up having to get.

300ex parts:
steering stem clamp bushing
airbox
rear brake parts (everything besides the caliper and line to it)
left foot peg and bolts for both sides


400ex parts:
plastic
tie rods

Universal parts:
shock bolts
clutch control assembly (lever, perch, cable, etc.)
tires

Edit: The diameter of the hole in the bottom shock mount is 3/4" give or take a hair. The width is the same as a 300EX or 400EX bottom shock mount. The inside hole should be the same too.

Project300EX
02-03-2007, 11:24 AM
Now that I look at it, it looks like it will sit a little low. I followed the dimensions for the bracket. I may just have to adjust the shocks a bit.

I don't think the bushings will work off the 300ex shocks. The needle bearing that goes in there will not slide into the 400ex shock. Looks good though.

I got my crank bearings and seals in this morning. I just got done putting them in. I'll probably order a rod bearing and full gasket set to finish up the bottom end. I've never seen a rod like this one though. All of the rods I've used have a cap at the bottom, but this rod is solid. I guess I have to take the crank apart. Anybody ever messed with a crank/rod setup like that?

Thanks. This actually is my first quad project. I've got a little experience with fabricating from my job (bodyman) and I took a small motors class my junior year of high school were we did a lot of welding. The reason for not using aftermarket stuff is to keep cost down. I'm a college student and only have time to do a small amount of vehicles. I also figured that I could show everyone some cheap upgrades for thier own 300ex projects. Thanks again.

every two stroke I've had apart has had the crank/rod you describe, these have to be pressed apart and pressed back together, I would find some one thats done it before, from what I hear they are tough to get back together
I think that's going to be a really nice machine!

02-07-2007, 09:22 PM
If your rod has play up and down it is bad. Side to side play isn't really a bad thing so keep that in mind. Also, if it moves just a tiny hair up and down I would still replace it just because you don't want to finish a good motor and have a rod go down.

I may paint the cases black and the cylinder/head something else.

Frame - blue/purple color in the pics
a-arms, swingarm, motor mounts, motor cases - black
plastic - yellow 400ex
cylinder, head - ?

go that sick purpley black color on the head :) but maybe re-think the yellow plastics, if your putting this much work into it, spend a few bucks for some custom plastics or ones that will look great on it.

I wish I could have found a stop sign, but this is the only one I've seen that's been down around here. I got the frame skid made and bolted up and have one a-arm skid marked off to be cut. I am leaving the decal on the sign and putting it facing down. :D


Also if anybody ever sees one down and wants to get it you'll need a 13mm socket and a flat screw driver. Atleast that's what this one took.

Thanks.

The swinger just bolts up. The only thing that has to be done is the mount for the shock linkage. It has to be made then welded or bolted to the bottom tube on the frame. Most people use a 250r shock for it.

I'm pretty interested in a 400ex clutch control (perch, lever, cable), shock bolts and nuts, and lower front shock bushings. I'm not sure how much the bushings cost new, so I'll just say a price and we can go from there. How about $35?

If you want you can just take the tires off the rims. I already have some rims, so that may save on shipping. It doesn't matter to me though.

Out of the stuff you listed that's it for now. If the rims weigh a lot then I'll just take everything else and you can keep the rims, but if they don't weigh much at all then you don't have to worry about taking them apart. I figured it might save some on shipping, but if they're the aluminum ones then they don't weigh much anyway.

The motor has to be a water cooled motor like the RM250 one I'm using. You can't put a radiator on a oil/air cooled motor. the 250r should have a radiator, or atleast I think they do. Right now I just have it held on with big, thick zip ties. I think it will be sturdy enough for it, but if it isn't I'll just go back and fab some brackets utilizing the holes on the frame tubes.

Ahh. I'm so pissed off right now. I just spent about two hours finishing up the motor then painting it and mounting it back on the frame. I put about a quart of oil in it to test for leaks. I didn't see anything for a few minutes so I put the recommended 800ml in. I wait a little while and the thing start having a slow leak. So I spent what seemed like an hour retorqueing all the bolts and finally get it taken care of. I was real happy at this point. Then I go to test my shift lever and the shifter shaft slides back into the case and off the gear. I then spent about an hour trying to get lucky and get the two spring on the shaft lined up on the post and at the same time get the gears lined up. No dice. So now I'm going to have to drain the oil, take the clutch cover back off and realign the shaft. I'll probably just wait until I get it rolling so I can get up in under it good to mess with it. Also does anybody know why the shaft would slide in the case? I noticed part of the housing that holds it was broke off, but I honestly thought it would keep it since there isn't much lateral play. Anyway end rant.:mad:

No problem. The can paint can go on thick, so you don't have to sand it with 400 like you would with an automotive paint. I sanded it smooth with 220 grit. Don't try to go to metal, just get it scuffed up with that. Flip it upside down and sand the bottom. Blow it off real good and wipe it down with a pre paint cleaner or a chemical like acetone. After that spray a light coat of Bulldog adhesion promoter over the bottom side of the frame. Wait a minute and do another light coat of it. Then wait 5 minutes and spray a good coat of paint over the bottom part of the frame. Wait a few minutes and put another coat. Repeat until the paint is uniform. If you're going to do clear wait a few more minutes and do 3 coats with a few minutes between each. Wait a day or two and flip it over and do the same process for the rest of the frame. Also you said you were doing this with rattle can like me. It won't be quite as sturdy as an automotive paint, so I'd suggest a frame skid to keep it nice.

also you can put the rattle can in hot water it will build up the pressure inside so the paint does not spatter

Hey project300ex I just sat and read most of this thread and this is an awesome project. Great work and If you can think of any 300ex parts you might need I may be able to help you out. Keep up the good work. Great work!


balls2da-wall.....theres no way you can compare your bike to his. Yours looks like you have serious cash tied up in it. I mean the front rims and nerfs alone are almost half of what he has spent so far for his whole bike. His is a cheap build. I'm not putting your stuff down, its nice but some people cant afford a lot of stuff. Just say pappy would do the PC for $75 which I don't think would ever happen.....then you figure at least 50 shipping both ways so thats almost $200.

it might have costed you 800 dollars to transfer the hybrid but you probably put a couple grand easy before you converted it

I'm not too worried about making it look nice. It's going to go on trails and crap. If I get stuff powdercoated and it gets chipped I'm SOL. If it happens now I can just drop another $5 for a can of paint and touch it up. I got the tires mounted, somewhat. I haven't got the lip to sit flush yet. Not many updates. I've got a sinuse infection or something right and honestly don't feel like getting off the couch.

Pappy pays for shipping one way. It cost me 40$ to ship to him from Iowa. And you never know...he very well may go that low.

That looks like its coming along great. I think if you need parts for the motor some of them may be able to come from a lt250r quadracer. You could go to qracer forum to check or sure.

Also what kind of welder did you use? Im looking for one and looks like yours does a good job. Thanks.

I'm using a Cambell Hausfeld flux core welder. It's a wire welder similar to mig, except without gas. Thanks.

Yeah, it bolts right up. The only thing that has to be done is you have to cut the steering stops off of the stem or frame.

Got my parts motor in today. I'm soaking the cylinder in laqcuer thinner to get that awful blue paint off. I'm going to run the cylinder the natural metal. I'm also bringing it to a shop tommorrow to see what size piston I need to pick up. I think it's been sleeved before. It doesn't look stock.

Still not quite sure what I'm going to do to match the intake tube to the carb. I'll probably weld up something with some thin wall metal tubing.

I just dropped off the jug at the machine shop. He's going to bore it until he gets the gouges out. Then he'll let me know what size piston I need. I'm hoping he'll get it done by the time I leave the house today so I can get it ordered.

i would run it like normal but if it comes up short weld a peice of tube to the end of the muffler and take it to the back and the tubing will give a real distinct sound.

I'll most likely have to run it under the radiator and between the frame rails. I'm pretty sure that if I run it between the cylinder and frame rail like normal the bend will be too sharp and cause problems. I plan on using a an FMF fatty pipe and FMF silencer and only modifying the piping to keep it simple. I haven't gotten a call back from the shop, but I'm about to head that way so I'm going to drop by.

mach1stang
03-20-2007, 03:47 PM
sounds cool but what i meant to do is if the muffler sits kinda far back from the back of the quad take a peice of tubeing and weld a bracket on it and weld it to the muffler it the tube will give the quad a super sick sound and it will give you the option to mount it in the stock frames hanger.

Thanks guys. I've got a Corvette that will hopefully be coming back from the frame shop soon. As soon as I get started on it they're paying a down payment, so I'll have some money for some funds. I'm also probably going to get a half sleeve, so I'll post that up too.


Oh, and they haven't gotten the cylinder bored yet. They had some in line before mine. He said he should have a size to me in the next few days.
