    1200 boxer throttle balance question

    I am in a state of confusion. I have been told that the 1200 engines are not owner adjustable in term of balancing the throttle bodies. How about idle adjustments? Is this all done by computer at the dealer now? I appreciate any information on this question. Thanks.

    They have a stepper motor that adjusts each side at idle, but you still need to adjust them at higher revs.

    Some bikes. Some with motors, some without.

    Thank you Dave. So it sounds like it is basically the same drill with the twinmax or other type manometer. Balance at 4,000 rpm or so?

    Never let the truth get in the way of a good story.

    Thank you for the reminder. I tell you, that Mr. VonBaden is no slow leak. We are lucky to have him in the club. Thanks Mr. VonBaden.
