I rebuilt my quad and ever since it will not go into reverse, has all 5 gears forward but no reverse. I did not however rebuild the trans, but mostly top end of motor. I took the clutch side cover off and it seems like it shifts into reverse and even feels like it, but will not do it running never "grabs" the gear like it used to, is there maybe something I over looked on the flywheel side of the motor a linkage or something, I'm assuming that I put the reverse selector shaft in correctly, none of my books or pictures show it all that well, ANY help would be appreciated, need it before next Thursday! Thanks
