My bike started sputtering like I'm not getting fuel. Bike has 8900 miles. I cleaned the injectors, changed the plugs. Bike sputters while in operation at about 6k rpms in any gear once warm. It runs fine when it's cold (first 5 miles or so). I checked it today while in neutral and the sputter is there. I've used sea foam, ethanol free gas and premium also clean the air filter. Now using techron in the tank. I'm at a loss on what the issue might be. Any and all help would be appreciated in helping diagnose this issue.

 

Hi , what is the engine idle speed when warmed up, have you checked your MAP sensor

 

500-1k at warmup. Haven't checked map sensor yet. Will give that a try. Thank you.

 

Hi, it should idle at 1200rpm ,give or take 100rpm, have a look at page 6-66 of your workshop manual for IACV operation
