86 the injector cleaner. don't bother, the only way to truly clean an injector is to pull them out and have them serviced. it's more likely something else anyway.

a little more info if you would please. has the bike just recently started doing this, or did you buy it that way. did you do something to the bike before it started. when did you first notice it. does it do it all the time or when it's just hot or just cold. have you checked for vaccum leaks? does it do it with the fuel lid open?

a little fyi the stock gearing is real tall so it is common for them to surge at low speeds and low rpm. unless of course you have a realy good map for YOUR setup.

first thing to check though is that the tank vent tube is not pinched somewhere.
