ok k6 gsxr 750

27k on clocks and i know the valve clearances need to be done (which im getting done asap)

would the cleanances if out enough cause symptons ...

at low speed escpecially around town the throttle response is shocking. jerky to say the least

if u back off the throttle slightly the whole bike lurches it doesnt reduce the power by a small amount nice and smooth it seem to nearly cut the power totally,,, and then back on.

so i have to click it up a gear but then it sounds like its running on 3 cyl......very strange sounding

27k and its had services every 5k.....gonna whip the plugs out and check them see if everythign is burning ok

all advice welcomed

many thanks

Dan
