Got a 1991 TY250r pinky and i am having trouble selecting gears, 1st to 2nd is the worst, 2nd to 3rd isn't quite as bad then it gets better as you go up the gears 5th to 6th is brilliant. I rang Birkitt and he says it will be behind the clutch. I have had that to bits and all looks perfect. Anyone got any ideas what it could be?
