I just had a thought, one I'm sure thats been bounced around before but still.. can you put a YZ490WR engine into a warrior or maybe a banshee??

or maybe a YZ250 engine into a blaster??

Just wondering

I am sure with some modification you can put that engine into either chassis. The mods may be very slight or may need to cut the frame, I dont know

but why dont you just put the yz426 engine in a 250r chassis and have the best bike out tehre instead of worring about that motor in a frame thats not the best?

 

Dont forget about the counter balancer or you will get alot of vibration which will kill your arms
