    *610, not 620. Cannot edit title it seems*


    I've had the bike for the last 10k kilometers. It's got a full TI system on from Leo Vince and should be jetted appropriately.

    It's always had a bit of a stutter at just above mid RPM at constant speed. No problem when accelerating.

    It's best described as if the throttle is every so slightly chopped and then turned back on in rapid succession.

    I've more or less ridden around it but it makes balance point wheelies in 1st near impossible.

    Someone mentioned that a possible fix was an aftermarket sparkplug. Anyone else with similar problem?

    Change the plug to a CR8EIX iridium plug, that should cure it.

    Will do. I am replacing the cam chain and doing the clutch cup replacement as well, so it might be a week or two before I get her running again.

    The CR8EIX took care of the stuttering problem :) Now it's my lack of skill that prevents me from doing decent 1st gear wheelies.

    Thanks!
