So the KX60 I just finished for my nephew is having a weird shifting issue. It downshifts perfectly. But once you shift from 1st to 2nd, from 2nd gear up the shifter sticks and you have to bump the shifter down 1/4" or so. Then it resets and shifts. I just replaced the return spring thinking it was weak and not returning the mechanism. The new spring didn't fix it. I took a quick video, my nephew is shifting on the other side and I was holding the assembly in (like the cover would do). You can see after second gear he has to bump the shift lever down to get the mechanism to to return to shift up again. Only on upshifts does it stick, downshifting is beautiful. I guess I might just order a new gear change mechanism because everything else is new including the shift lever on the other side. The shaft is not bent I have checked it three times now. My nephew is dying to ride and I am getting irritated. In all my years of wrenching I've never been stumped before, LOL.
Any ideas? Please tell me what I am doing wrong because I am about to just make the bike a two speed, LOL.
