Evening all, i have a problem with second gear, a few days ago whilst in second and accelerating, it jumped out of gear and back in again, and all was well, today it did it again in the morning, by the afternoon it would not go into second, instead it made a horrible grinding noise. going down through the box it engages intermitantly then starts grinding again. the gear indicator does not show 2, it shows 3.. all other gears are perfect just 2any ideas would be appriciated. the bike is a 1995 11** with a post 1997 box. i put the box in about 2 years ago. no problemes up till now. Thanks in advance
