Thanks for all your Quick replys( I have never had one from SAPL yet )
I have replaced both fuel lines with oem new ones, done the cush drive rubbers and even replaced a perfectly good set of sprockets and chain for new( on advice from suzuki)
no I never saw any flow charts for the injectors although suzuki told me they took them out?
I have cleaned all 7 of the screens and bought a new "golden' internal filter.
This problem did not creep into the bike it just suddenly happened shortly after 48k, it used to take at least 28km of riding before it would start and it would be in for say50% of a ride( you could ride 30 or 40km fine and then get on a highway stretch at100 kph and it would arc up and then stop again after maybe 5km and run fine for another stretch)
Now its getting to the stage where its hunting all the time at light throttle, all the mapping changes have been done on a dyno in fact the same one which set the pc3 up initially and it ran fin for a couple of years ( dyno is Serco's Dynojet Dyno so it can upload straight to the pc) although I think a problem in diagnosing light throttle problems on a dyno is that the dyno puts too much rolling resistance on the bike and masks the issue, I have been an A grade auto mechanic since 74 and have often found limitations on dyno results i.e. my bike has gon from 156 to 160rwhp in the course of trying to solve this issue but it still runs like a pig.
thanks again for your imput
