    R1100RT Throttle Body Knock

    When I found this, while looking for another problem, I was blown away. Originally I had thought I was looking at the expensive and time consuming complaints of cam chain tensioners or guides when I first noticed the knocking sound from my bike. I was absolutely certain that I was going into an engine rebuild along with my imminent tranny tear down.

    What I found was this (video quality isn't great, but listen):

    Something so simple, easy to repair and best of all, not a lot of money, $230.00 for both throttle bodies, full kits, OE Bing.

    And it proves my point, keep it simple. When I start taking my own advice, I will quit drinking beer.

    Yeah, that's not going to happen.

    So what was making the noise? Did one of your butterfly shafts come loose in the bearing?

    the shaft & bushing wear out.

    MUCH less expensive from Dan Cata, over at advrider. I purchased 2 kits from Dan, for less than one Bing kit. Just sayin'.
