I've had a bit of hesitation when pinning the throttle open at high-ish (6k+) engine speeds, changed the air filter + fuel filter and after a quick run up the road it appears to have got rid of it.

I just used a standard £12 filter from Wemoto, ordered Tuesday, arrived today.

Fingers crossed the filter will sort your problem out, this thread seems to be never ending.  That said if you removed all the flirting from CRH and Ade it'd probably be about 2 pages

these are average figures as i did the test four times,should be about 160/170 psi ,with 40,000 miles on the clock i was not expecting top pressure, within 10% and i would of been happy,the low readings on cyl 2 + 3 has got me thinking  :eek


i then disconnected the plug caps in turn to see what these figures mead in real terms....


                                disconnect plug lead no 1...............little bit flat but idles
                                disconnect plug lead no 2...............flat but wont idle
                                disconnect plug lead no 3...............little bit flat but idles
                                disconnect plug lead no 4...............little bit flat but idles
                                disconnect plug leads 2 + 3............flat but just about idles

so iam now thinking HEAD GASKET blown between cylinders 2 and 3    the bike runs fine between 4/8000rpm so parhaps the pressure of the 2 cylinders is masking the damaged gasket at mid range but at higher rpm the pressure is too great and the stutter returns  ......sounds a bit mad...but could be
