Anyone know what could be the cause of this sputter when I accelerate. I thought it was water in the gas I cleaned out the gas tank and it is still happening. Could it be the timing? Any thoughts.

Thanks Lenny.

hey Len,
I had some problems once with my bike sounds like the same thing........
I switched out the plugs and it helped but when I up graded the plugs to the split tail screamin eagle ones it went away for good.
I also like the mobil gas premium seems to make it run better.
Hope it helps

If your bike is fuel injected, I have been advised that there have been several instances where the fuel line inside the tank will get a pin hole in it from where it rubs the inside of the tank. This usually happens when the fuel level get a lower and if you top it off it will run fine. Just a thought.

hey lenny82

your post seems outdated or old.....to old to not have left an update as to the cause or source or cure of the problem and i am sure i am not the only one who is outta breath waiting for this knowledge and hoping we get it before we encounter the same problem and have no solution. hey lenny82, hope you are still out there... busy..or riding and have fixed the problem and are just waiting for the time to get online......thanks in advance. please inform us if the bike is fuel injected.

Check the ignition module? It monitors the spark w/out the movment of P/C. Also more and more gas stations are using 10% ethanol. Might need to start adding a fuel stabilzer?

Thanks all!

It turned out to be a clogged injector. I finally ran some injector cleaner through it and it was back to normal.

Thanks again for the helpful thoughts.
