Thanks to all of the help from you here at TT, RM videos, a buddy who's a mechanic and of course, a service manual! Replaced my 3rd and 5th gear pinions along with a couple bearings, crank kit and bearing, and new top end. The bike started right up with no problems and is running strong. I must say that's a great feeling. One question though, every once in a while when I'm kicking I get this loud puff of air sound...like when you try and kick it with the wash plug in sometimes. Anyway, is this normal? I don't remember hearing this before. It's just every once in a while.
