    Hi - I just bought a 2002 V11 Sport that has been converted to carburetors. During test ride, I noticed the bike has above normal :bow:vibration in the pegs and handlebar after about 3500 rpm.

    Is that typical?

    Can it be "tuned out"?

    Need to balance the engine?

    Thanks
    Pete

    Did the vibrations start when it was converted to carburetors? Perhaps they need syncing. Even so, you are unlikely to get the two sides to track as well as the injectors do.

    I agree w/Dave, sync the cables on the big end of rpm range. I usually do carbs at the rpm I ride normally. You might try doing the sync at 5K rpm or 6K, then see how it feels were you normally cruise in rpm.
    FI bodies had a solid arm across for sync, carbs are 2 cables that stretch at different rates each time you twist it up.

    They all tingle 4000-5000rpm. The weighted throttlemeister bar ends helped alot. balance your TB and that is good to do as well.
