Older bike with stumble

[Longfellow]

What about older bikes with stumble? I have a 2010 that stumbles also.

Try using a concentrated fuel injector cleaner first.

My 2004 has a slight stumble/miss that occurs under heavy acceleration and around 2500rpm. I haven't found a way to get rid of it. I have tried new plugs, air cleaner, Sea Foam and Techron. So I just said the heck with it. It has had it for years,

Does your FI light ever come on?

My 2008 had a bad stumble when I got it with 6800 miles on it, two years ago. Not sure if it was replacing the spark plugs or the whole bottle of Techron but it hasn't stumbled since.

If you have tried all the above, have you all checked your valve spec's?

longfello I too have a 2010 and it stumbles when cold. when the temp gauge reads between the first and second line on the gauge. I just let it warm up a little and the stumble is gone. When I first got the bike used in 2013 with 16000 miles on it I almost dropped it when it stumbled all of a sudden. took it back to the dealer and they said it was normal. I have owned plenty of carberated bikes and never experience it. I guess honda did not do a good job of programming the fuel injection. I started searching the stumble on another forum that existed before this one and I saw that what others did was just let it warm up a little before ridding off. It works for me. gives me time to wipe down the bike.
