My 89 yz250wr got stolen about 2 months ago, I bought a 94 yz 250 to replace it and miss the WR. I got parts of my 89 back this weekend, including toe motor, but the piston was stolen and it lookes like the motor was sitting a while with the head off. I was wondering if I could put the top end from the 94 on the bottom end of the 89 (I would have to do a long rod kit) and put the motor into the 94 frame. Essentially I would have a wr 2t
