Hi guy's
had a good weekend on my bike and have come to a decision that
it must be electrical, as changed carb with another,run with needle at top with clip at bottom
no change,checked crank seals nothing,must be electrical,will let you know how we get on this weekend oh and
yes the power valve ...

Hi
the power valve is working , as when cover is off it will move, also when it had the air leek
it went really well but would bog a little after about 2k on full throttle and really low down, mid range was good also run on a bit ?`.
if the crank seals are ok could it just be running two rich ...

hi
have tried this and no info available.
thanks Steve

when i took out the main jet Saturday it had no numbers on i think but to be
honest i didn't check properly as i was just cleaning the carb ,but will check
this weekend.
some one said it may be an air leek as it runs on when you shut the throttle
and sounds like it's pinking like a four stroke ...

Hi and thanks for reply,
looks like running standard jets no numbers i think
power valve is working fine, got a fmf fatty on with fmf back box,when cold she works better,

thanks steve.
