I posted in the yamaha forum that I had a perfectly good 87 yamaha XT600 motor with all electronics. Its actually coming out of my XT that has experienced some front end bending. So my question is, what four wheeler could i fit this engine into. I have been told the warrior frame would work, but would like to know if I had any other options. I have access to a motor shop and custom welding any brackets i might need. So please let me know any frame that could hold this big thumper, I just finishd my old project and need something new. Thanks in advance for any help!
