Two of them I turned the screws about three full revolutions before achieving an acceptable tightness! I rode the bike about 100 miles after tightening the clamps and it ran perfectly! Most of the miles were on the freeway, but I came to a full stop and put the bike in neutral no less than twenty times today, and each and every time it immediately returned to a perfect 1050 RPM idle! Before I can declare my idle issue is completely cured I must put more miles on the bike, and do some in town, slow speed, stop and go riding, and for a thorough test, I need to perform the in town riding in elevated temperatures. I will perform addition tests ASAP (hopefully next weekend), and report back. I urge any of you guys who are experiencing the idle problem to check your throttle body hose clamps, as SportsterDoc has been recommending.

If this indeed proves to be the case, I might just have to pull an admin power move and change his user name to "CB1100Doc". Big Grin

If this proves to be the case, you can pull another admin power move and change my user name to "CB1100sUkr" (having sold mine!). Haha...oh well.
