well you make this sound like an AA meating
hi my name is Nick i'm 16 and i like hair in my food ugly chicks and pearced anuses.

lol

well anywasy welcome i think some people have done some of the conversions in here but i'm not sure but the bigest prob is the kickstarter

[plkmonster2]

welcome to 3ww! :-D :-D :-D :-D :-D prolly the biggest prob, like nos said, would be where to place the kickstarter, and i dont know if the engine is a direct fit, or not.

Welcome to the board. Always good to see new people around here, and since you're failry young, hopefully you can stay a while.

The kick starter is a problem. I am sure HondaATC might have a few things to add to this as well. He is amid a confusing ATC500 build.

[Joel85350X]

One more thing, document the entire build with pictures and maybe even a list of what you did. Pictures say a thousand words, and the guys around here love a good set of mid-build pics to drool over.

Its harder than you probably want. But sense you have the motor, just chop away. Buy a custom exaust from www.trinityracing.com or something like that. Or you can build a custom exaust, but custom wont be near tuned, and will hurt your performances. They now can have premade ones from trinity for that conversion.

I HAVE A 500R,, the kicker is the only problem i have , the pipe i had biult looks like the stock 250r pipe so there is no room for a full lenght folding kicker , the kicker shaft is 1.5 inches deeper in the frame than the 250 kicker too, so i built a slide on spacer thats removable cause with it on and wide enough to clear the brake pedal its to wide to leave on to ride... it goes under the seat ,, its ok for the dunes,, cause you get use to keepin it running ,,, i haven't seen one yet that looks good and works good too,,,,

but i am still looking tooo

Bentwrench, I didn't mean to step on the "more mature" fellas feet, just glad to see a newbie. :)

Nice to see another Purdue Graduate.

Actually I'm doing the other 500 conversion (4 stroke). I really didn't have much of a problem with the kicker on mine. I did have the problem of it not getting enough throw, but I got the brain storm to just take it off, and take the slack out of the shaft (You know how when you fold out a kicker, it goes about 2-3 inches before it catches and starts actually turning the motor) And after I did that, no more problems with kicking it. Now I've just got to get it to run :rolleyes:

still havent gotten that 500 to run billy? shock roll

[sobe962002]

mine is coming along fine i have the motor in and mounted all i have to do is put on a chin im whait for my +8'' swingarm then i will be done but it a 2002 Cr500R motor on a 86 ATC frame. its defenitly posable i have seen pic and now i have dpne it. but yes the kick start is a problem so i think antell i figure it out im going to popstart it. lol

[jtr]

what about the motor mounts will i have to weld or are they the same . i have a 86' 500 and an 86' 250r?

[200x Basket]

you have to weld them. i used a cr500 fmf pipe and i did not have to change the lenght so it did not affect the tuning. dont worry if you lose a hp or two because you will have a bout 20hp to spare!!!!

[plkmonster2]

yeah, like basket said, use the header off the stock 500 pipe, and the rest off a 250r.

[KASEY]

BUMP START???? LOL RIGHT,,,,,,, i thought the same thing when i first started,,, there is no way to bump start my 500 in the dirt ,,, 40 mph on asphalt 5th gear was the only way i ever got it to start,,,, but i don't ride on asphalt thoooooooo,,,,,,,, build a kicker you will need it

[plkmonster2]

i have to push start my 110 and it is always a pain. what happens if your off somwhere by yourself, and it dies? and the grade is flat? now a 500 would be HARD to push start on gravel :shock: probably couldn't even get it to turn over... :rolleyes:

[NOS_350X]

lol bump start i cant even get my 350 to do that it just drags the tiers

[sobe962002]

i know but i dont know how im going to build a kickstart of it. if anyone knows how please let me know.

[4cylinders]

how far does it have to stick out? the kicker of course. have you checked a cb 750 kicker? did you see the atc500 in atv action a couple months back? really cool seat!!! I'd like that on the monster!
