Bought a 82 Yamaha IT250 last spring and have been struggling to get it going ever since. I'm in need of a Cylinder or Sleeve but I just can't find one. Is there anywhere I can go for these parts? I'd Prefer a Sleeve but Yamaha dealer said they stopped making them. Would one for a YZ250 fit maybe? Also When I took the cylinder off I found like 7 or 8 gaskets. When I put just one back the piston would come up and hit the head. Any Ideas? Thanks in advance for any help I'm REAAAAAAALY Desperate.
