All -
I've got a 400F with ~24k miles, probably original. I've owned it for the last 2-3k miles, and its always run and shifted great. In fact, this bike definitely had better shifting than my previous SOHCs, a 500K and a 350F. A couple of weeks ago I went on a ride with some friends, and I loaned this bike to a friend (who rides) so I could ride my GT550. Just before the ride, I adjusted the level of the shifter, it had been too high and I didn't want my friend getting false neutrals (as I had been getting) because your toe had to go over horizontal to shigt up.
Anyway, I rode the bike yesterday and its not engaging first gear very well. Basically to get first I have to be moving. Either downshift while decelerating (my usual) or if from park, I have to engage first while walking out of a parking spot. FYI I always shift this bike with the clutch (up and down), but I can't comment on previous owners or on my friend.
What could be causing this problem? I believe that the clutch is properly adjusted. I'm worried that he could have somehow bent a shift fork or some other expensive and time consuming part to replace. Anyone have any thoughts? I just restored every other aspect of this bike, but the engine ran so well I left it alone.
Thanks - Matt
