Well I am getting occasions where the engine revs up, and the gear takes a second to "catch" if you will. I'm not good with clutches at all, so sorry if I'm being vague. It feels like it isn't fully in gear for a few seconds, even though I'm certain that I've shifted it into that gear firmly. But this is only some of the time and not all of the time.
However, I will definitely hop into the carbs again and see what happens. I was always told that I ride my bike so often that the carbs should be clean just from the constant use! Guess that that isn't 100% true lol.
The carb boots on the engine side are only 4-6 months old. I bought them both brand new. Though I've never replaced the ones on the airbox side, and can't recall checking them lately. I'll pay special attention to those when checking for leaks...never thought of leaks just because I have new boots.
