I've been working on learning to shift without the clutch on my 09 450. Well this past Sunday I was having some trouble shifting into 3rd at times. Sometimes I feel like I'm pulling up on the shifter hard and the bike just won't shift and other times it's smooth. Not sure if it's me or the bike yet. Anyway this past Sunday I was on the power and tried to shift and it sounded like it got caught between gears. There was a grinding sound and then it poped into gear. It didn't really act any different afterwards but I'm wondering if it might have caused some damage. Any opinions or similar cases?
