best bang - yes, it has something to do with the 950's compatibility with the Chiro. The thump does NOT occur with the Odyssey. If this enlightens any of you engineers out there as to possible causes of this extremely annoying problem, please post them.

I did track down the email address to Fred Pham, the head engineer of Chiro before it went out of business, but he did not respond to several emails.

I found some solace in reading I was not alone with this problem, that it is not unique to my situation. I find it curious that no one from Outlaw has posted any comments on this topic. Any way to let them know?
