That's not why I need the info Jim, and I hope that's not where this thread ends up. We will probably never know if it was the cause or not. I have met Hammer and consider all BFMC friends. I don't care why he died, I just care that he is no longer in the wind.

It does seem that there may be a problem with the FBW system though. For safety sake, everyone with it should have it checked out...... as long as HD knows what to check for I guess.

TBW can be electronically 'reprogrammed' to the OEM default settings by performing the reprogramming sequence as outlined in the '08 Touring Service Manual on page 4-17 under "Installation of a new Twist Grip Sensor". H-D Customer Service is now recommending that instead of the published '3 second' interval instead use a 10 second interval.

My '08 Road Glide was increasing the idle from a normal 950/1000 rpm to about 2000 rpm over a few on/off cycles. The above 'reprogramming' cured the problem each time it occurred. Now with about 3k miles on the bike, it does not seem to be reoccurring.

I have found no information anywhere that the 08 throttle sticks.

Did you change the factory grip?

uweldit: No. I noticed that my basic idle speed was increasing by about 100 rpm almost everytime I went thru a on/off cycle with my '08 Road Glide. I never experienced any racing or surging while riding. I complained to my Dealer and they referred me to H-D Customer Service. The Rep told me that they were working on a computer 'flash' to reset the on-board computer to stop this situation. While waiting for this new computer 'flash' to be prepared, I was to follow the reprograming technique in the manual (page 4-17) except the four second interval was to be changed to a ten second interval. Since, each and every time my '08 started the fast idle situation, the reprograming worked. To my knowledge, the H-D new programing fix is not out to the Dealers.

I now am approaching 3k miles and the problem seems to be resolved. I went thru about 10 or 11 on/off cycles today and the idle remained exactly where it should all day. .............. BC

Thumbs up 08 Throttle

Very sorry to hear of the loss of your friend and will keep him and his wife in our prayers. We have a 08 FLHT 6500 miles no problems so far will keep an eye on it though.
