2006 street bob with the 88” twin cam, around 3000-3300 rpm’s I get a sputtering or almost like a clogged fuel filter? It’s only if I hold it at those rpm’s trying to just cruise. 1st through 4th it seems like it happens in those gears. It accelerates up no problem, only happens when staying at those rpm’s. Replaced the tps already, no luck

 

Needs more fuel at 3500. What's it do there? Plugs good? Maintenance up to date? First sign of a fuel filter on a STOCK FI is idle. A modified engine may be different if the tuner adds fuel to idle mix.

And codes?

 

at 3500 it runs fine. Plugs were done a couple years ago. Could be worth changing. All fluids have been changed. Forgot to mention bike has an Andrew’s cam with a dynojet power vision tune. Just scanned it and I’m getting a p0118 code

 

How is the bike at idle and low RPMs?

 

That looks like a coolant temp code. Wanna try again?

 

idles fine, rpns up until 3000 are good

 

 

Odd. Quite odd.

Those are historic codes. Clear them, change your plugs, see what happens.

 

Is it sputtering or chuggung? possible primary chain ajustment? what i had with mine but mine is carbed.

 

it’s definitely more of an engine sputtering than a chugging from a chain
