well its allrite now mate. bit slowish. could do transmission setting up proper. its runnning a speedcontrol plus 6.5g rollers. think maybe too heavy but dunno.
sounds heavy, but depends what your running, just check that airbox is clean, carb is clean, air mixture screw is set correctly aswell, usually 1-2 turns out, (roughly 1.5) and while your at it, take fuel lines off and make sure there clear and working properly... make sure fuel tap is working properly, and what ive done, put an inline fuel filter in the fuel line someware as it helps reduce Shit that gets in with petrol,
