i want to replace my stock mojave engine. i want something cheap but good. im looking in to racing but usally ill be riding in the woods and sand areas. so what do you guys think. and how hard will it be to put the motor in. what would i have to do to the frame? thanx

 

how about a KX motor???
i think it would be sweet if you could get it to work.

 

i had a 91'kx250 motor in a 87 mojave,it works well if you wire it right line up the sprokets and mount it right it will do around 80mph
