Yes sir, just home from the swim meet. Son did great. I'll take your advice and not pull the head unless I can't see inside or if I see something alarming. But it seems to run fine. I know my compression is about 125-126 on both cylinders which makes me confident no real damage has been done, unless I am wrong here. Maybe I'll borrow a boroscope from work for a better look for scratches, dings, or scraped areas inside the head. The piece was laying in the step area where the plastic tube meets the carburetor. When I saw it, I felt it asking me to take the bike out and introduce alot of airflow so it could wreek havoc on my engine. Glad I found it first. In hindsight, I wish I would have spent more time yanking the bike apart when I first got it. The PO admitted that he wasn't very mechanically inclined, but had receipts from service done by BMW Detroit.....Hmmm. Since I have no idea of the part's origin, I'll go ahead and do the rebuild and inspect the heck out of it. This will get me back again to the point where I will also seal better where my metal boots attach to the airbox w/RTV (previous post, which you replied). Probably should have taken it all apart back then too, but that was a half off thing I did on the intake to clean the exterior a bit. I really tried not to disturb the carbs. Thanks for your replies, everyone! I love good advice.
