do u have any ideas of a air cooled 2 or 4 stroke simple non complecated engine that i could replace my almost new mojave engine with?fast?lots of power?reliable?somthing that will fit good in the mojave and align with the axle sprocket

 

yea a mid 70 s yamaha it 400 motor there 2 stroke and they rip i measured up the engine size and chain alighnment and its very close

 

thanks what do i get this motor out of what is it called?

 

it comes from a mid 70 s yamaha it 400 dirtbike

 

are you thinking of the yz490? that would be pretty scary in the mojave frame! i know a guy who has a tecate 3 motor in his mojave (its scary but awesome) and right now hes puttin a ninja 500 motor in another one.

 

no im not thinking of a yz i said IT
