So took the bike out on Sunday it’s only running in the back cylinder. Seems like the front will hit here and there seems to run ok asking as I’m giving it gas will die when idling Any advice

put seafoam in the tank to clean injectors
check spark plugs
Check plug wires
take air cleaner off and use q-tip to clean IAC of carbon.

10-4 it had been doing that a few weeks ago and it ran ok when I but some octane booster. Did about 300 miles on it and about 4 miles from home started doing it again. I did remove fuel injectors cleaned them they were spraying fine. Gonna have to do the spark plugs and and wires. Seems like it catches air and sputters.

clean the IAC
May take several tries to get it really clean.

Will Seafoam mess with the liner in the tank?

With any EFI bike the first step should be to hook up Protune and check for faults

No -- I run it regularly.
Actually keep small bottles on the bike and use it every other tank or so and the bike runs great.
When I told Puppy about it he couldn't believe the improvement his Harley had.

Absolutely correct.

 

[Cruz Dog]

Thanks guys. I’ll do both. How much sea foam are you putting in a tank?

 

[Jersey Big Mike]

Well I read the can and do the math.
When its bad I'll run 1/2 or more of a can thru in one tank

Thanks. gonna try and hook it up to Pro tunes this weekend
