Same problem here. I was in a parade yesterday and the only way that I could find neutral was to shut her down. After awhile, my clutch hand got a little cramped. I'm waiting until I do my 1000 mile service, then I'll change to Amsoil Severe Gear 75W-90 and do a very careful clutch adjustment. I'm hoping that will work.
The Amsoil gear oil will make the neutral problem better.
