    '11 RT RPM fluctuation

    probably just a bit of paranoia on my part. Any one else experience RPM fluctuation a few hundred RPM when the bike is in neutral and you hold the throttle in the 2-3.5kish range?

    I haven't experienced any fluctuation, but then I can't say that I recall trying to hold the throttle in the 2,000 to 3,500 rpm range while in neutral. I guess I'll have to try this. To date though, I haven't experienced any throttle instability during normal use.

    Why would we want to hold the throttle at 3,500 while in neutral?

    TB sync for one.

    There isn't any fluctuation under normal load.

    Off idle TB sync should be done slightly off idle. 1400-1800 RPM is specified for the earlier hexheads. I assume it is the same for the camheads.

    I think its normal. Its the computer chasing the o2 sensor with no load. Does it really matter?

    Matching the cables just off idle is where it works the best. The further open the throttle is, the less it matters.

    David and my two cents.
