Can you provide a more detailed explanation of the occurrance? Exactly what happens or what is taking place when your issue occurs?

sure, ill try. you can ride it when its cold, and its fine, up shifts and downshifts, shifts kinda hard, but not too bad. as it heats up, it shifts harder like hard as in hard to switch gears, and then sometimes on a down shift more in higher gears 4,5,6 it wont shift, or hangs up between....
