Well, one would think to go back to the last change. Perhaps something amiss on the change out. Anyone can goof, so don't be testy with your mechanic. LOL
First, make sure the clutch is adjusted right, and done so when overnight cool. Then as VJ suggested look over the linkage, and adjust to your liking. I like mine just off my toe when it is under the lever, and it helped with the funky Vic shifting when I did this.
There was another thread recently about shift problems. I think the guy actually bent the shift link adjusting rod. Said he wasn't being rough with it, FWIW. He was advised by several members to check the linkage, be sure it was correct, adjusted and not binding, and did so after he bent something, problem solved. Live and learn.
Your problem seems different than the one I was talking about, but do the easy stuff first and pay attention to detail. If you aren't willing to, do you think someone else is?
