my bike runs fine great pull through to redline in all gears.

but if i stop on an incline and try to take off the bike wants to die and cut out.

i have to keep nursing the clutch till i get a bit of speed up and its fine then.

my nsr 80 and 125 never had this problem.

i have cleaned the carbs and no difference compression is good.

powervalve is working 100%
