Two days ago I took my 99 cbr f4 for a ride. It had previously been kicking out of second gear. When I got to the turn around part at the end of the road, I kinda got on it a little hard. I shifted into second from first and it popped out and did the grinding deal for a second then caught and made a loud pop. On the way home it made a grinding and popping noise like maybe I may have broken a shifting fork......Even does it in neutral. Any Ideas?
