[woodsracer144]

hey, i have a extra 250r chassie and i found a cheap crf250f and i wanna have a bike but do the bike also... any one do this? how does the 250 motor handle in the quad? any major problems? any pics of this i would really like or even a bid too.. thanks!

I'm right there with you. I'm also building a small bore bike this winter. I'm using the YZ250F motor though. I'd say it should be a lot of fun to ride, but nowhere near the torque of our big motor bikes.

yeah... i really liked my blaster but i love all teh power that sin my 400 yanda... but i really wanna try out this bike thing... what chassie are you gonna use?

I built one a few years back using a 250R geometrey CRF450 chassis. Pretty easy build for me.

I'll be building one of these bikes for my boy using a stock 87 trx frame. I'll post up some pic's as soon as I can. It will have a stock 04 crf250 engine.

416exmx, How did the stock crf250 pull the quad? Do you think It will be enough for a light weight kid to tear around on?

Check out kidsonquads.com. they have been doing them since 2004, they usually use the rmz 250, kfx250, or the yfz 250. the motors are shorter( dual cam) vs the taller honda, and they fit right in. I saw One of their riders in mi. and he was smoking the 450 A class on one.

The yamaha motor is short but it comes with the external oil tank that needs to be custom fit in the frame. On jbatvracing.com he built one awhile back for Thomas Brown. If it were me, I would use the Honda just based on teh cleaner install.

416exmx, that is one clean looking bike.
