I've read up on this on the web at it seems this was probably cauesd by the PO (riding too hard). I'll be riding along and I go from first gear to second gear (at a fast rate of speed). The gear will engage but then at about 6000 rpm or above it will pop back into neutral. I find that if I take my time and really push the selecter hard, it will engage and stay in gear with no problem. Also shifting down from third has no ill effect. It is notabbly harder to change from 1-2 then any other gear (probably because of the neutral?). My plan is to take it easy for the season, and open the transimission and replace the possible 'dogged' 2nd gear this fall. Are there any things I can adjust in the mean time to mend this issue? Has anyone done this procedure? any tips? Thanks, Colin
