Sputtering a slower speeds
We just picked up a 2008 1100 Custom for my wife with about 11,000 miles. Accelerates nicely, no issues at all. When maintaining 25-40ish MPH it sputters a lot. It starts smoothing again around 50+ MPH. Also, seems like idle RPM's are low and it turns off after idling for a couple of minutes.

So far all I've done is clean air filter, replace plugs and run 2 fresh tanks with 5 oz of Sea Foam each time.

Any help is greatly appreciated. Wife is a little bummed having to deal with this.

sounds like a dirty carb.i hear berrymans is better suited to clean carbs. keep the idle up between 950 and 1050. i would pull the carbs shoot carb cleaner thru all the passages. remove the pilot jets, the jets have small holes in there sides spray with cleaner and use the wire from a bread tie wrapper to clean through out, reassemble

Thanks! Do you know how much Berrymans to use? The tank is about to hit reserve and I was going to run it down as much as possible. Appreciate your help.

RE: Sputtering a slower speeds
i only use it a couple times a year as maintenance, in your case i would double the dose.i've had the carbs off a dozen times it gets easier. https://sites.google.com/site/vstar1100k...carburetor i've posted a link about the 1100 ton of information.
