LOL - sounds like a parts bike - hope your primary and clutch are now adjusted to the loose side, if true then the shift shaft adjustment was done and your shifting should be great now. This is an easy bike to fix, but you have to get the wording right if you want folks to follow you and help. I been at this a long time so I can probably give a better educated guess than anyone through sheer experience, however, jet knows his stuff as good as the best out there, so be nice, he always trys to think outside the box to help folk, and right or wrong his guess will be better than most anyone elses except maybe me or the rare references from ErikO or TerryP. To get to the tranny you have to totally tear down and/or split the case depending on what your doing to the tranny - lol - so yeah I understand his side as well - relax - no one here is trying to hassle anybody - just trying to get to the truth - a touchy subject - lol
