i have a sbp shift kit and a 8 speed derailleur.
it has been running great (for about 8 months)up till about a week ago when it started grabing the chain when it was reved hard.
now it grabs hold of the chain and sort of jumps the derailleur .all the time.
i have changed the chain twice the wheel (gear cluster ).and had a good look at the deraileur .even gone to a complete 7 speed system no luck
has any body else had this trouble with there kit or maybe have an idea.
i have a grubee gt-5 with expansion chamber ,ported ,programable cdi and seprate coil,and delorto copy carby .
