Hello Forum, Hope someone may know of this problem, my xt600e 2002 is consistently cutting out/spluttering if you use it at full throttle at high speeds, for instance motorway it is useless i have to keep it at 70 to stop this happening. It has a predator exhaust and has just been dyno'ed and rejetted - it had the problem before this, since dyno it is quicker and runs better, but i am flummoxed and it is ruining a great bike for me. I have tried carb cleaner, before dyno, no joy, could it need an uprated fuel pump or new fuel tap, i was wondering if it could be a vacuum occuring, or is it ht lead? Please throw some ideas this way if you can, thanks Teeb. java script:emoticon('', 'smid_2')
