OK, long story short, Suzuki LT500 engine was rebuilt. A long time passed before it was put in the bike and now the shop won't touch it to help fix it. It runs and will go into First gear and Neutral but will not shift into any of the other gears. Have it apart now and have tried moving the fork like thingy (sorry for the non technical terms) that is moved by the shift lever to different spots on the other part but has not seemed to help (saw some old posts about that on another bike). I have done plenty of car motor work but never worked on a two stroke motor so I am at a loss for this problem. Any suggestions or help will be tried. Thanks.
