Rough Idle

[tudvmjt]

My 2008 busa is idling very rough... It also hestitates and sputters at low RPMs... I didn't ride it much last year so I don't know if that has anything to do with it... But the problem started about a month ago... I thought I may have put the wrong grade of gas in it so I added some octane boost and rode it hard... The problem appeared to be fixed but when I took it out today its running like crap again any ideas? FYI 17K miles

Drain the fuel, add fresh fuel and add some Chevron Techron injector cleaner. May need a filter too depending. Easiest most likely attempt to solve.

Did you get this figured out?

AFS. Air (filter), fuel, spark (plugs). Replace all with fresh and your problem should be fixed.

If not, the next step is a clogged fuel line/filter, clogged injectors, etc., but I doubt this is the case.

Valve adjustment may be needed
