It is not normal and don't let them sell you anything you don't want.

 

Need Stage I and a tune it will run properly.

 

Update: had almost empty tank with 87 in it, running slow on a warm day sitting in traffic. Stopped for dinner, filled tank with 91, opened lowers vents, temp outside cooled a lot with evening, road the open highway home. No pinging at all. Guess ill have to spring for a new exhaust system... wasn't going to do that. Oh well...

 

What does that mean?? It pinged with 87 octane....it stopped when you fill it with 91 octane and now you have to buy a new exhaust system because why?? If you "wasn't going to do that" then why do you feel you need to now? I'm not following the logic with that.

 

87?? read your owners manual..........

 

Beechnut, I am just south of you here in the Land Of Entrapment. Same issue with my stock 2010 StreetGlide. Best gas I can get here is 91 octane but still have the pinging. Its not there ALL the time but its there and bugs the crap out of me. I just installed a set of FL-eXIEDs from Nightrider hoping that will help. So far with about 150 miles with them it seems like LESS pinging but its still there. Many here suggest it all has to do with what gear you are in, I wont argue that but dont think that is MY problem. Becoming more and more convinced the only real solution is aftermarket exhausts; a/c; and a new tuner of one brand or another. Another $2K just to get this engine to run right and rid of the EPA mandated crap that the MoCo must use.

 

Oh yeah, that's good advice right there...

Seriously. I know FM is a good company and all, but let the dealer try to solve the issue first.

And, if they sell him a PCV, I'm not certain the spark-retard system will still be active. Running good fuel helps.

 

If it pings on 91 octane with the stock cal at altitude Harley really needs to fix the base calibration.

An A/C and exhaust is just going to make the situation worse, not better (until some form of fuel management is added). The problem is in the calibration, not the parts on the bike.

 

Yup, your dealer and MoCo should have some kind of documentation of your pre-detonation issues if any other issues ever come up. Let them try to resolve it first. A FM fix would work great but it won't help you with any other future claims/issues...

 

Yeah, had 87 in it and was the best I could get at the time in Northern Colorado when I needed it. Miss spoke on exhaust.
