Crf motor

[brewster426]

Wondering if a 05 crf motor will drop right in a 07 Trx. Got a dirtbike and a fourwheeler in the garage. Wondering how easy it would be to do. And I understand this isn't the hybrid forum. Just figured more people would see it over here.

you will have to make new motor mounts, the cases are alot different between the crf and trx motors. the kicker will also have to be modified because the crf kicks back not forward like the trx and the cases dont accept the trx idler to change the direction
