if your trying to put a '97 engine in another frame..they all are pretty much the same frame all the way back until about ' 89 i believe..only thing they changed as for how the motor changed..is the way the top motor mount's are above the rocker box. this is the only thing i know of. keep in mind..if you change frames..then you have to change out all the wiring..c.d.i box..all of the electronics..the switches throttle control..stuff like them..can be left on the old frames..your main thing is the wiring..and reg/rec..and c.d.i and the alarm units. everything else will swap out.Which models of 4x2 Fourtrax 300s will an engine from a 1997 4x2 Fourtrax 300 work in?
Thanks,
Kenny
