    Rear gearing !!

    I have done a few mods to my SX , One of the first things I should have done was to put a 43 tooth on , If you have not yet, IMO Do it now, If you can believe it , it makes your bike more enjoyable to ride.

    A 39 tooth sprocket is a blast as well! I barely get out of third gear on country roads, and it will still run a fairly quick 1/4 mile at the track too.

    Never really looked while racing. It does climb though. Check out www.gearingcommander.com

    Hey quick question... So does the ecm that is calibrated to rear sprocket tooth count, does the ecm now know the new speed and does it count miles correctly?

    There is a tone ring on the rear wheel that is used to read speed by the IC on the dash. The ECM uses RPM & speed to calculate the gear indicator on the dash, I believe.
