Ok, I've searched and read about the 125's having issues....but can't exactly pin down what has just happened to my 250 this morning. Bike has WR 3rd through 5th gears, pretty much everything else is stock. Riding at the track today, bike was working flawless, as usual...then, went back out after a good solid session and a few corners through the first lap I roll out of a corner and find myself in neutral...I upshift, neutral still...I concentrate to ensure a positive shift and still neutral...I shift down and find a gear. Up shift again, neutral. I pull off the track and shift up and down, finding false neutrals and sporadic gears. I ride back to the truck and investigate. Once the bike is in gear, it doesn't pop out or do anything weird, but I can upshift until I'm tired, and keep hitting gears and neutrals....every once in awhile the gear shift lever would kind of "stick" after down shifting, too... Through the search function on here, I've come to believe that splitting the cases is probably in order, to be on the safe side. But, it also seems like it could be the shift stopper mechanism, as well?? Any clarity would be appreciated. I've done top end rebuilds before, but never have split the cases....advice? Thanks!!
