hi all

Not so long ago i installed a 2 speed in my buggy with out to many problems. i have only taken it for a few runs and im impressed with the extra top end and its quicker off the mark, but yesterday i took it out and it wasn't changing gear staying in first, then after a few runs it decided to start changing, took it for another run this morning an again it wasn't changing any ideas on what to check, i have tried to adjust the clutch but didn't help.

regards Mark
