got my 450r a arms on (almost)

[maddmatt02]

I only had the right side arms so I just used em on both sides just to to relocate the brackets. I bolted the right side from arms out to the tire and measuring from the rim right under the ball joint to the lower frame rail was 14" with 400 arms and with 450r arms with the arms at the same angle, using same wheel from rim to frame its 15 1/4" so I got 2 -1/2 additional width vs 400 front setup.

my a arms shipped last tuesday so they should be here this week along with a few other part so this weekend I should finish the welds(I only tacked it with a flux core and will finish with the gas shielded since it looks WAY cleaner) and have it rolling and maybe even with the 450r rear end, when I get it done Ill take some pics.

alright, heres the pics, one is of a 300 with 400 arms, rest are of my 300.

[monster300ex]

ok good to here
post some photos

[maddmatt02]

got the front end set up, Ill take some pics tomorrow. I didnt measure but man that thing is wide! looks like its as wide as the 400 my boss had with +2 arms. rear end looks kinda narrow in comparison now, maybe just some wheel spacers back there.

[maddmatt02]

girlfriend took the camera today to the party for the 4th tonight so I cant get a pic right now, maybe tomorrow. I did a measurement though. the 400ex has LSR +2 arms, and my 300 has 450 arms, but 400ex parts from the arms out, and I measured caliper-caliper to rule out any toe in/out,camber, wheel offset differences that could ruin how accurate a measurement from the wheels would be. and caliper to caliper its only 1/2" narrower than a 400ex with +2's. part of it is my arms sit a little closer to level but not much.

rear end isnt quite as wide as his durablue +4 axle, but its pretty wide, and the axles way further back than his 300.

sucks no mail today cuz I got so many parts coming and we go to oregon again the 20th so basically I wont be ready at all but if all my stuff got here soon and I dont run into any problems it could happen(but when does nothing unexpected happen)

[2muchquad]

keep us posted,i would consider doing this later on when i need something to do;) Plus stock 450r arms are cheaper than after market 400ex arms.You'll love the 450r rear end if you do it,its way lighter because its aluminum,losing weight is the same as adding hp too:D

[maddmatt02]

I am actually in the process of it.

already have the swingarm, carrier, axle, locknut, sprocket and bolts, wheel hubs. and already paid for and/or in the mail is 250r rear shock, rotor and hub, caliper stay, rear caliper/brake lines/master, 300 swingarm bolt/brake lever, 400 shock linkage.

also in the mail is my piston rings, gasket kit, cdi, etc... and I got the whole engine waiting to overhaul.

Im just gonna do a cheap rebuild and leave it 282cc or whatever it is. was thinking 11:1 and a cam, but I only want it to be a 300ex engine til I find a nice cr500r or maybe a yz426....

was thinking crf250 even cuz I heard they have more power than a 400ex, btu still less than 426's/450's. but Im thinking a cr500 will be alot cheaper to get alot of power out of it, plus alot cheaper for the engine itself.

and about cheap, I actually got my 450r arms, all bushing sleeves, ball joint castle nuts, brake lines from master to calipers, tie rods, and brake banjo bolts and brake line bolts for 50 bucks shipped. so now I got an extra set of right sides I paid 40 for that I have to sell.

[jay80]

Looking good. I just got my 450r swing on yesterday, still need to set up the linkage and get a rear shock. Measures about 46.75" to out sides of tires, not to mention it added a few in length.

[maddmatt02]

just rebuilt tyhe engine for it yesterday but ran into a spot I have to epoxy where they threw a chain, and I got my sleeves/dust caps for the swinger and got my snap ring for my axle locknut so I should get alot farther today, but still havent gotten my shock yet, soon I hope. also the 400 linkage is a little narrower than the 450r's but Ill just put spacers in it for now.

[jay80]

When I was installing the swing arm with all the bearings and dust boots I had to open up the frame a bit for the swing arm to fit. Now mine is a 87 250x frame so IM not sure if you will have the same problem. IM not talking a lot, about 1/8 of an inch. I also cut a spacer to go in between the swing arm mounting points to help keep out dirt.

[TWISTED DINLI]

looks good.

[maddmatt02]

just talked to my boss today and actually he is running the 300 frame from the parts bike they bought to get the 250x running, then twisted it in a race and used the 300 frame, so mine is a 250x frame, and with the sleeves/seals dust caps mine fit right in, I also went to HD and bought steel tub and cut a length between the sleeves so they cant slide out from the needle bearings. got my 250r shock today but I didnt have time to try anything but look at it, but the top of the shock, the sleeve through it and caps makes it too wide to fit in there, and even with no caps it wont fit. the body itself would fit if the inner sleave was just as wide as the body, but does everyone just grind the inner sleeves down and not use the caps?

also a bit more progress has been made, got my axle snap ring, rotor/hub, locknut, caliper stay, etc but when i go to put it all in the little thing that slips around the post on the swingarm that the caliper stay fits around that lets it slide when you adjust the chain, well I didnt have that so I couldnt bolt my axle in. do have the sprocket bolted on as well as left wheel hub...

and now the only thing I am searching for is a starter solenoid(might just buy a high amp relay) and a front master cylinder and an exhaust system. probably more little things here and there. eand of course the trip now and then to home depot for bolts.

[TRX-330]

are u guys runnin the stock 300ex motor, if so isnt it gunna be hard to ride a wheelie with the 450r swingarm cuz ther longer if not ima do that to mine so please let me kno

[maddmatt02]

im sure it will be harder to wheelie, but if I nail it then I will be faster than the guy with the same power and a stock swinger. and if I use some body english Im sure Ill be able to still pull it up. if you have any work done to the engine than im sure it will still wheelie no prob, maybe not in as high a gear. my boss's 330 pulls up all the time if you got any kind of traction.

[TRX-330]

thanks

[2muchquad]

They're still easy to wheelie with the 450r swinger:)

[maddmatt02]

hope so, I like the wheelies. anyways it looks something like a quad now, might post some pics in a minute or tomorrow.

[maddmatt02]

the nerf bars were on this frame when it was wrecked, right side hit and it broke the bar that mounts between nerfs and to the frame, so i just had to bend one peg mount back and make a new tube for the center to clamp to the frame. little work but hey they were free. also got the harness today but didnt route it on the frame yet.

the oil line banjos as well as the rear master brake joint rod or whatever its called are on order at the local quad shop. pick it up tomorrow hopefully. just noticed my rear rotors bent though now that I have the caliper bolted on, at least its not that bad.http://i164.photobucket.com/albums/u9/maddmatt02/quad4105.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad4112.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad4110.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad4111.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad4113.jpg

[Caseys 300ex]

I think you should get a better relocator bracket, That one looks weak and i dont want it to break on you and u get injured. That would be bad. But nice build. Looks sweet so far.

[maddmatt02]

oh, also still thinking of upper/lower shock bolt solutions. its a 12x66 bolt for a 300 upper but most other hondas shock bolts were 10x##, I think the 250 lower is also a 12x## but stock bolt is too long cuz of different linkage and a 30.00 bolt cuz of being greasable. so I am gonna take the linkage/shock and probably just the whole quad to tacoma screw and get what I need, and probably have to drilla few things out. also I was wondering what you think of this idea for the mount for the linkage. looked at the 450rs setup[ and got this idea.

take angle iron, and overlap one side so it makes a c channel, and where it overlaps drill through one so I can rosette weld the two together, then notch the overlapped section to fit around the lower rear frame rail and have it stick straight out the back, and then make a mirrored peice for the other side. drill a hole through the overlapped section of each for the pivot bolt. and obviously weld the part around the frame that I notched for it.

[maddmatt02]

only reason it could be weak is I didnt leave a ton of material above the upper bolts, as far as the rest of it, the 330 my boss has had for years has had one just like this, except for about 1/16th thinner, and maybe a slight bit more material abobe the bolt but almost none between the upper/lower shock mounting holes. and this specific one was put on his quad and made it a week in oregon with no signs of failure. the plate doesnt sit completely flat on the table but it was scrap so I dont know if it originally was perfectly flat. and the bend in it now is basically so slight youd have no clue until you set it on a flat table.

also, forgot to add, the thinner one has been through 3 or 4 seasons of flat tracking and the quad has tumbled more than a few times, the frame twisted on the worst one and the bracket still came out fine.

[Caseys 300ex]

sounds good

[born2ride14]

thats sweet but im confused your frmae is still bent and r those 400ex arms on now or 450r?????????

[TWISTED DINLI]

its lookin good.

[monster300ex]

looks good man and will work good to I wood think so
but can you do something for me
what is the measurement from the a-arm bolt to the center of the ball joint
on the top a-arm

[jay80]

I would make a back plate for the top mounts of the front shocks, not just a front one like that. Other than that looking alright.

[2muchquad]

those 400ex arms on now or 450r?????????


thats what i want to know too.;) You could actually take 2 pieces of channel and put them together and drill through them both and into the bottom of the frame for your linkage mount,you wouldnt even have to weld anything.

[maddmatt02]

they are 450 arms, thats why I had to relocat the brackets. and not sure what youre exactly talking about with the linkage. when you say channel Im thinking a C channel like truck frames that arent fully boxed. and sure I could drill through two peices and bolt the linkage to it, but I couldnt just bolt it to the frame. first I dont want to remove material from the frame by drilling it, also if I were to run bolts through the channel to the frame, not so sure about that. the load from the linkage pivoting arounbd the bolt wouldnt be the same as the load pushing against 2 surfaces bolted together, especially since the load is centered on the bolt that it pivots on but has leverage aginst the bolt to the frame, plus it would be a flat surface to a radiused surface so bolting them wouldnt work so well. i might be picturing something completely different than you got in mind. either way I got my pipe to fix the nerfs as well as 3 feet of 1/8 x 1- 1/2 x 1 - 1/2 angle iron to make the mount. just need to buy a spool of wire for the welder. spent almost 80 bucks today just for some castle nuts, master linjk, plug, brake master part, and the steel.

anyways heres some pics, guess the shock mounts not as thick as I was thinking by memory, but it is still pretty beefy.

got the front plastic today, I got some krylon fusion paint and am painting the right and left front fenders, and rear fenders gloss white, painting the tank plastics and front center peice yellow and making a seat cover that is black on the sides and back and yellow to run into the yellow plastic.

solenoid is 75 from honda so im buying used for sure

http://i164.photobucket.com/albums/u9/maddmatt02/quad5007.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad5006.jpg http://i164.photobucket.com/albums/u9/maddmatt02/quad5005.jpg

[maddmatt02]

oh yeah, and im going to lose the "teeth" the previous owner gave the quad. wanna try and fab a 450r headlight in there down the road but running is #1. front hubs are gonna go yellow and frame/arms going black.

[born2ride14]

i have more ????s wel first r u gonna tear it back down to paint the frame?r u gonna get new fenders? r u gonna clean ur motor it looks like someone took a dump on it??? anyway this in spireing to a project withh a300ex frame, 350x motor, 350x rear, 400ex a arms ,250r plastic 400ex carb that thing would rip but right now i have 1 thing to fix a friggin polaris . but after that i was thinkin bout doin a trx90 pit bike motor conversion so ya

[maddmatt02]

not painting the frame til i get my crf450 built to put in it and the mounts fabbed up and frame gusseted, which comes later, for now Im just spraying the welds a yellow color. plastics are being painted, and yeah the engine will be cleaned. but its got no carb, no exhaust, valve covers arent on cuz I still have to adjust the valves and the hole still needs to be epoxied which i think Im doing today, so i got 5 holes that will let the grease/grime/water in if I clean it now, so i am going to clean it real good with the pressure washer and some oven cleaner when its done. and maybe some new white maier when I get the new motor since it will be fast and wide and long its gotta lok good too, depends on how good I do with the paint and seat cover, and how good krylon fusion adheress, I did use it when I redid my interior in my car and my dog walked on the console all the time and her nails never once scratched the paint off, and its not a little dog, shes a 60lb pit. so not too big either but I was sure it would tear it up.

[Angie537]

i put 450r a-arms on mine too.. my dad cut and welded them to fit tho so i didn't need the brackets

are those 450r shocks too?

[2muchquad]

Those arent stock 450r a arms,those plus 2?

[TWISTED DINLI]

no they aint stock. they are to wide to be stock.

[maddmatt02]

they dont look like 450r shocks to me, and you have to have brackets of some sort? the a arms have to mount to/ and pivot from something. maybe he cut/welded the brackets in a new location, which is what I did. cuz I dont see anything that makes me think he actually cut/welded the arms themselves. plus the upper front a arm brackets look very close to the bumper bolts, which is wherre mine mobed too, bumper barely fits there anymore.

got my bars, cables/ twist mounted today, had to leave early though so i didnt get the nerfs fixed or anything else done.

[2muchquad]

wel first r u gonna tear it back down to paint the frame?r u gonna get new fenders? r u gonna clean ur motor it looks like someone took a dump on it???

How come its so hard not to say anything if its not positive about sombodys project?Im sure Matt is investing a lot of blood and sweat into his deal for his own satisfaction not to please you.I can tell by your writing you must be young.Engage the parental controls to keep you from wondering onto this site if you cant play nice.Have a nice day:rolleyes: Looks goodMatt keep it up,do your thing bro;)

yeah there 450r shocks too..and yes there stock aarms..i dont kno what my dad did to them but..and the mount bracket is the stock 300 bracket is what i meant ...there mounted the same way 300ex shocks are

[2muchquad]

you have heim joints instead of the 450r stock ball joints,if those are stock arms,how did he do it?:confused: looks good though

[maddmatt02]

well you could cut off the stock mounting points of the arms and weld on threaded bungs and thread in heims I guess. and now im confused, they mount just like 300 shocks? what about where the a arms mount, or is that what you meant?

and, I do want it to look good some day, but my first goal is to get everything functional. I am going to make the plastics and seat look good right off the bat, frame... no real point in that when I plan on stripping it/ modding the mounts/ and gusseting it later on. probably remake the upper shock mounts completely also so I dont need upper relocation brackets and lowering blocks at the bottom. then Ill PC it maybe or just paint it since it will for sure get chipped either way I bet.

thanks for havin my back 2much;)

and on those shocks, wheres the res. ? cant see it in any pic

[maddmatt02]

wow, just noticed they are heims at all ends, as well as looking at that lower shock mount on the arms, no way those are stock. stock tubes are same O.D. from ball joint to pivot and shocks mount in a bracket on top of a huge plate between the forward and back tubes of the arm.

[jay80]

Have you gotten yours up and running yet? I finished the 250r rear shock/450r swinger set up. Also did 400ex arms and 450r shocks up front. Its real tight, haven't had much seat time on it yet, just a few zips on the back 40.

[maddmatt02]

no, parts took a long time in the mail, as far as I know I still dont have my rear fenders, cdi, regulator. havent found exhaust yet. well I have but not for the price i wanna pay for how they looked. also just got the carb the day before I left and the guy put it in a box that BARELY fit it and had absolutely no packing around it and it got damaged and wants me to lie to UPS about it and deal with it myself to try to get my money back before. so I am gonna get paypal to deal with it, cuz ive done it before when I was the seller and I had tons of bubble wrap and crap around this mirror and they still didnt give me the money back cuz they inspected the packing and determined it was insufficient somehow. also I havent gotten the rear linkage settled. its on hold now til aug 29th cuz I had to fly out to cali for my grandmas funeral last friday, then straight fron there to new jersey to work for a month so no chance of getting the quad running til I get back, then hopefully since I wont have a job for the week and a half or so before I move, I should be able to get it done before I leave again. and when I do finish it I dont even have a back 1/8th all I got is a back balcony. but Im moving onto 10 acres down in arizona so plenty of space to ride there.

[Justin#38]

those a-arms are stock but her dad did some modding to them and the shocks are stock too

[Jake250ex]

I know this post is kinda old...

but since we cant get info Ill take my guess at it. It looks like the lower shock mount could have been cut off and turned upside down. But I would almost put money on it they aint stock. Look at the brace on the lower A arm on the inside of the shock, close to the frame. Ive never seen a stock 450 a arm like that.

If they are stock, he took them a long way and props to him :cool:

[honda4life72]

theres no way there stock 450r a arms , there long travel 450r a arms . with the 300ex top shock mount being so low u can use long travel arms to make 450r shocks fit
