When up shifting from 1st to 2nd every once in a while my bike will slip into neutral and if i try to up shift again it will go into 3rd, just seems like it skips second all together. Seems to only happen when the bike gets good and warm and only happens maybe once out of twenty shifts if that. All other shifting is normal. I want to change out the oil and see if that helps. any other ideas. I've heard the detente plate can come loose or break, but not a lot of info in the manual. same with adjusting the pawl, but not much in the manual. I dont think its worn dogs, as once its in gear it doesn't slip out. maybe a bent shifting fork, but wouldnt that give me more trouble shifting all the time? any thoughts
