Surging Idle
Hi folks,
I have a 3 week old '08 Ultra that started to surge during idle today. I rode to work and back, parked in the drive for about an hour, got back on it go to supper with some other folks and noticed when I came to the first stop sign that with the clutch engaged, at idle, the bike would surge from 1k to about 1.5k. It would sort of go up and then down, up and then down. Not really fast, but say 3 seconds at 1k rpm, then slowly increase to 1.5k rpm... then slowly drop back to 1k rpm.
We rode on to supper at Logans (not bad ribs), got back on her, cranked her up.... no surging, no problems. Rode to service station, filled up and made a ride through town, stopped a few more times and no surge, no problems.
Any ideas???
Thanks and God bless !

RE: Surging Idle
There is a chapter in the 2008 Touring Model factory service manual that addresses this issue. There is a procedure where you can correct a high idle by turning the ignition switch from off to run I think 4 or 8 times with a few second pause in the off position each time. It must be done with the kill switch in the run position as well. Thing is though......this is for correcting a high idle....not the surging you describe. As MACK said though.....I have have heard of the DL to remedy the surging problem works well though.

RE: Surging Idle
cool beans guys, thanks. I thought it a little weird that it did it, then didn't do it... but all is possible in electronics and motorcycles...[8D]
I think I will make the ride to Horn Lake tomorrow. I was trying to old out for the 1000 mile service, just have nearly 800 miles on it in 3 weeks. But alas, it's 100 mile ride to my dealer.... might take the long way and take care of the 1000 mile service and this problem at one time.
thanks again for your help.

Hi rshwetz,
Thanks, I'll check it out in the manual. I also took a trip to the dealer today, got my 1000 mile service and they updated the computer system, no problems now. But I will check out what you refered to in the manual also. Thanks a bunch.

RE: Surging Idle
Hey Hotshot,
I got your PM and could not figure how to PM you back. I was the Zapp's distributor in Central Louisiana for about 10 years. I gave it up to go back to college and now I teach 3rd grade. That is my connection to Zapp's which is a great chip! Nice bike! Nice color! Looks just like mine.

RE: Surging Idle
I was close to Tupelo this weekwnd. The wife and I road from Louisiana to Tuscalousa, Alabama Friday and came home Saturday. We stopped at Chunky Harley-Davidson in Meridian, MS on the way. The bike did great! We road interstate all the way.

RE: Surging Idle
Glad you had a great ride. I haven't been down to Chunky River yet, but scheduled to ride in the Dixe Thunder Run at the end of this month. Ride from Tupelo to Meridian, spend night, then ride to Biloxi the next morning. It benefits our local 155th National Guard families. Great cause and fun ride.

Have a great week, hope we can run across each other some time.
