builtin me a hybrid

[1fst400]

well I sold my 400 motor, got me a 450r motor on the way. sent the check to pappy today for his 2004 R motor. Bought a stock 05 carb off ebay.

Cant wait till I get my motor so I can start on the motor mounts. I think Im going to do somthing like this.

Kinda copys the houser frame.

J/k lol tim

[BORY]

it should deff rip when its done.

[bh2285]

you have too much time on your hand my friend...oh yeah any money give me some.

[1fst400]

ya, I have to much time. Not as much scence I got a GF. As for to much money,, far from that. I work my but off for the past 3 summers. During the school year I have a part time job that barley pays for gas/dates/fourwheeler parts that brake.
My dad does pay for alot of my fourhweeler parts, moast every time I buy a part like a sprocket or somthing he buys it. But the bigger stuf I buy, shocks, engine, a-arms, swing arm, ext.

I have a race on the 18th this month. Think I can get it done it time?

I think so, this is what my budies yfz that I was fixing looked like, Race was 4 days away when I took this picture, Cases where split on the motor. I had it together in 2 days with no shop manual (backordered).

THINGS WICKED MINTTT

[400exMO]

You definentely need to keep us updated. I think Chino886 knew somebody who did that conversion. Search his name, he had a bunch of pics and info. on it.

[1fst400]

I started on the frame today, Only so much I can do before I get the engine.

But I discovered some cracks in my frame:eek2: :eek: :eek2: :eek2:

They are neer where the front shocks mount on. I made some sick gussits useing a plasma cutter and iorn worker at my cousins welding shop. I wanted to stamp stars in them, make it look like a LSR, I attemped to cut a star into a peace of steel. looked more like a circle with spikes.

[1fst400]

cracks.

[1fst400]

These cracks must me new in the last 3 months. I dident notice them when I put it together from the frame up then.

[400exMO]

Just asking, how do you fix a crack like that? It'd be ugly to weld a bead around. And I don't think you could get any backing with that tiny of a crack.

[1fst400]

I will probly bring it over to the welding shop. They have a TIG welder there. On the tig welder I can weld A very nice looking bead/ invisible. That gussit will hold it all in place pretty good. only thing is when you weld around a peace of tube it ruins its strength. Notice moast all welds on frames go in line with the tube.


when you weld around the tube it will crack rait next to the weld moast times.

[1fst400]

did some welding today. got all the gussits in for the front end.

I put some designs into the gussits, trying to be fancy

[1fst400]

damn I need to wash my quad. lol thing is filthy!

[WhiteYFZ]

in the gussets, is that the walsh symbel.. i cat see to good but itl ooks like it a lil.lol.

[1fst400]

ya, I did my best to make a walsh symbol on one side and a lonestar star on the other. I dont have any walsh products tho, just think it looks cool. a start is like imposible to make, took me a good hour.

are you sure? I've taken seminars on building truss, the grid looking thing you hang theatrical lights on-like at concerts, they weld all the way around tubing....the key is heat control. you'll need less heat from about half way around to finish the seam due to the pipe heating up from when you started the weld.....

[1fst400]

your probly right, Just what I heard fom a guy. Im 16 year old kid, how much could I posibly know.



After puting the gussits in today I decided not to weld the crack at all. the gussit should hold it plenty. and I will be able to keep an eye on the crack so I will know imediatly if the diffrent engine is puting to much stress on the frame. Im not going to pc the frame for a cupple weeks of riding.

[zedicus00]

you really should weld the crack, hes right though after you get a good beed started pull the tip off it a little farther so you push less heat into the tubing. or you can do it in half inch blasts, weld, let it cool completly, weld, let it cool completly. just be very carefullwhen you pick up where you left off its easy to poke holes when starting off at the end of a weld....

[1fst400]

I hear ya on the whole welding thing. I took a welding class actually, it was 2 time per week for a month or so. It was at a colege, full of adults. Me and my dad took it.


I had the welder set fairly high for the tubing on the frame. That way I could move along at a diecent speed. Transfering less heat throu out the frame. When the tubing looked like it was getting to hot like it was about to put a hole, I aimed the tip more twards the gussit piece because it was thicker steel it soaked up the heat.


Problem when you pull the tip back it doesent get to good of penetration and the metal cracks off from the weld.

[ohsobad_chevy]

Dude, I'm not trying to be a dick, but why didn't you just buy a 450r. Did you want something different from everyone else or what?

[1fst400]

im emotionaly attached. Parts for a 400 are cheeper also. axle, a-arms, ext.

lol...any updates man?

[1fst400]

today I put it on the back burner, waiting on my motor....

I took the blown transfer case out of my jeep today.

[1fst400]

should have my motor by end of day thursday. Then its hammar doun.

Only things that I think I need to get are exhaust. throttle cable. clutch cable mabie.

Hopefully by tuesday next week I will be driving it around.

[CTmxyfz]

are you interested in my axis shocks still?


Is that thing going to be ready for southwick on the 18th?



I also plan on swapping a trx or crf into my 416 chassis soon i hope. It does well and proved itself last year in the B class. I still ride it better than my yammi:eek:

[ingleful]

its gonna rip when its done...when ur finished with it email me the pics or jus post em cuz i wanna seee em:D

kb_boy_jiffylube@homtail.com <----- email

[250x_kyle]

not bad...Im thinking of doing the same thing. ill will probably get the motor next summer and during the winter i will tare it down and gusset it send it out for pc. o and how hard it it to extend the kicker? i think im going to have all the mounts done by jbracing though.. im going to take a fabrication/welding class for the next couple of years 5 days a week for like 3 years. so realy once i get the motor i can do the fabrication like its nothing plus the instructer is friends with my dads side of the family and my mom works with a woman whos husband owns a big wleding company.

[1fst400]

I am useing the 450r quad motor. No kick start extendor needed. It has a foward kick. only reason that im realy useing this motor is availibility and cost. It was there and at a good price.

[rustee]

hello 1fst400

i did that conversion a few weeks ago. it was much easyer than i first thought. kick starter will work but it is a pain in the @*#@. it wont really tuck in right. if i can help you out let me know. my pics are here http://www.exriders.com/vbb/showthread.php?s=&threadid=227736. once i was done with the mounts the bike was finished in 3 days if you see the dates on my pics from eng in frame to track. good luck !! rustee..........

[rustee]

hello ohsobad_chevy

for my self we wanted to have something diffrent. for the price that it cost me to do this i cant buy a 450r in race ready condition. the 400 was already there untill we blew the motor.the machine is lighter than a 450r /shorter and not as tall and has, i feel a better steering geometry. the bike flys and handels extremly well for tt and flat track. that is what we built it for. and we are giving fellow 450r guys as well as yfz guys fits out there. they cant stay low on the track under extreem power like we can. but we do own a 04 450r also and we love that bike. but it is no match for this little spark plug. just my 2 cents. rustee.........

ps we have even been told we are cheating!! i love it.

[1fst400]

thanks rustee. Where are you from in NE? Mabie I could stop by and see the bike in 1st person.

[rustee]

hi 1fst400
i sent you a pm i am in ny state!! good luck on the project!
rustee.......

[1fst400]

I sent u a pm.

[1fst400]

woot

[1fst400]

fits in there mint

[1fst400]

I had to flip the rear shock around, It hits on the back of the engine. Only dounfall is that it now hits on the air boot.... Eventually a remote ressie shock will have to be bought.

[1fst400]

making an exhaust header is going to be a wooter. Im going to try to come up with 2-3 stock headpipes, and try to get it to work with a series of cuts, welds, bends.

[WhiteYFZ]

looks nice.. now get to work . :devil:

also, u gonna do the blue clutch cover ..red?

[1fst400]

hack job to get the kick lever to fit.

[1fst400]

hack

[eganracing]

very nice job! keep up the good work.

[rollie]

lookin awsome man, PC that clutch cover red:cool:

[yokeracer]

Nice, now how's the power?

[1fst400]

Originally posted by yokeracer

not running yet,

need,
exhaust pipe
hot start cable
throttle cable.
clutch linkage part? part that holds the cable on the motor..
cdi box


Need to
weld motor mounts, raidator mounts, oil cooler mounts. Put on all eclectrical

[yokeracer]

Looks like fun, all I need is a donar bike now!

[Live2Ride300]

Looks awesome man! Got any pictures of the motor mount brackets?

[theTman]

you gonna be done bfore this weekend man? got southwick in 3 days!

[1fst400]

I could have been, But pappy hasent got around to giving me my cdi. So far this guy has seem to be a little bit of a slacker.

and I dont want to pay the extra 80$ to race at southwick, we only have a cupple races there.
Im not going to the make up race in NY either.

But you will see me at capeway.

[bh2285]

how much work was it to get the motor to mount up?

[1fst400]

so far I have spent about

5$ on cut off wheels.
I used scrap steel. but probly 30$ worth of steel.:confused:
10$ on misc hose clamps and hose for intake.

Tonight I got all the motor mounts made. I just need to sand the Powder coat off the frame and weld them on.


how much work was it... well if you know how to weld, its real easy.

the rear shock resivor does hit the engine. the air box does need to be cut and moved back. Adaptor from carb to air boot must be made, real easy. Just a peace of 2-1/2 in pipe with hose clamps and hose.
The radiator doesent fit as good as I would like, To tall... I guess a 250R one works better, I just angled it forward some.

Oil cooler lines had to be bent to get it to fit somewhere.

Hole had to be cut in plastic for kick starter.

[1fst400]

I sold my motor for 1,100$.

I bought this 450r engine for 2k. Little steep. but its a low hrs engine.


So far I have spent mabie 100$ on misc bolts, pieces, parts. But not much.


Is it running. WELLL. its SO close. Waiting on my hmf. and Need to just finish up some loose ends

[1fst400]

brap

[1fst400]

:D

[1fst400]

:p

[eganracing]

looks good! nice work if i do say so myself.

[1fst400]

Hack job intake

[†2005 400ex†]

hows it run?

[1fst400]

DROVE IT TODAY.

woot woot, thing goes prety good. Love the way it handles. Started 1st and 2nd kick no problems. I dont event have the hot start buton hooked up yet.


I did several drag races vs a 06 R on payvment. In a parking lot, so there was only enough room to get mabie hight 4th gear. We Swaped riders. whole 9 yards. We came up with that, well first off I'm the best at drag racing out of my budies... and that my quad is behind about 1/2 quad length by 4th gear.

I have some vids of me riding it/ drag racing. CRAPY vid. But youll get the point.

[figair]

Your quad turned out nice...Are you happy w/the 450r motor or do you think you wish you wouldve went w/the yz or crf motor?

[1fst400]

Only reason I would have wanted the crf motor was power. This motor has plenty of that, I wont need much more for quite a while.


VID.

Keep in mind in the vid, I was on the red quad ( mine) my budie was on his 06 450r. Keep in mind that he weighs 120 lbs... I weigh 170. thats why he beets me by more like 1 length, when it was 1/2 lenths with equal weight riders.


http://media.putfile.com/Fast-hybrid-1st-ride

[AR15 guy]

I like it.

Guy at the local track had a 400ex/yamaha 426 hybrid. He was killing everyone on it.

[figair]

looks good...

[LT250RMan]

Looks like it runs good, nice build man.

[1fst400]

prety good for a 16 year old kid hua?

[Tri-valleyracin]

I race in 4 stroke B normally. Thinking of entering in Open B also. I did pretty good with my 400 motor, this coming weekend at capeway ought to be FUN. See ya there!


Hit me up on IM if you have it, my screen name is mittimj

[wolffie]

that thing is AWESOME man! you should be really proud of that. i wish i had the time to master the skills of welding and fabricating! keep up the good work, and lets see some action shots:devil:

[1fst400]

crapy shots taken from the vid.


I would ride it tomorow. But I lost the shifter... :o . It fell off in the sand pit because I dident tighten the bolt that holds it on good enough I guess.

[1fst400]

brap

[1fst400]

ye haw

[ss440ex]

We need a HYBRID section!

[rustee]

ss440ex i am all for that~
nice job1fst looks great i see you got the kick starter to work for you! i was thinking about shortning it on mine this way i wont have to beat up the plastic. we are using the goki electric start kit on ours. but would like to also have a kick start in case the battery goes dead. whitch the goki kit dose seem to do for some reason it dosent charge the battery up that quick.
great job i know what you were up against. rustee...

[trict_out]

lil faster than the ol 400 huh? lol nice build congrats youll turn a lot of heads with a 450 motor in a 400 frame:D

[250x_kyle]

i have a hybrid message board its in my profile. anyways i just thought id let yall know

[1fst400]

yea

[eganracing]

very nice! let us know when u win a race.

[400exMO]

Looks good. how's the power compared to the 400?

[1fst400]

the power is about the same. Smoother tho, more controlible.

[Tri-valleyracin]

thats got to be one of the best hybrid i have scene. i like the fact its still has quad motor.

[LT250RMan]

Originally posted by 1fst400

I think the 450 would have way more power than the 400ex engine.

[rmz250]

That thing looks good man! Nice job.

Still I dont think a 400ex with a big bore kit, high compression piston, race cam and a full port and polish still wont have has much power as a 450R motor.

i dont know whats all in the 450 motor. if its just a pipe then i can see how it would be the same cause my 440 can beat a piped 450, that was when i had the stock carb on it now i have the 39 fcr that i bought from 1fst400, but havent raced anything since i put that on.

[LT250RMan]

Why did you go with a 450 quad engine and not the YZ450F dirt bike engine??

[1fst400]

I wanted to stay away from anythign that wasnent honda. I just havent had as good of luck with anything eltse.

[cbr]

hybridbuilder.proboards99.com

[440challenger]

Look good man. You can use the stock trx headpipe and slip on with no cutting. I dont know why you needed to do that to your intake either. I used my stock 400 air box in stock locatin and just
hoged out the air boot a bit so it stays on the 450 carb.

The oil cooler you can unbolt and flip the lines to give you more length to mount the cooler in front of the rad. Also mounted the coolant puke tank on top if the rad ,fits right in there and to check the level all you need to do is pop the hood.:p

The top motor mount your missing , i used stock trx450r lower engine mounts fliped upside down. I also used a rear 450 shock fliped around. Nice build!!!! Only if there was a way to fix that dammn kickstarter,i hate the way it looks on my quad!

Heres a lil vid of a jump i made up last week testing out my setup..
