My 2011 Ultra Limited is pinging. It pinged when the bike was stock so I had a stage 1 carried out hoping it would cure this. I put on the SE air cleaner with Supertrapp 4" stout slip ons. Bought the SERT and had the dealer dyno it. Gained 8 hp and 9 ft lbs of torque. Bike still pings wether in 5th or 6th anywhere from 2600 rpm to over 3000. Any ideas to cure the pinging. New dyno by other shop?
My 103" Electra Glide with Stage 2 runs like a champ up here in BC on Chevron 94 octane. When I rode down to Arizona earlier this summer, it seemed the further south I went, the lousier the fuel got. In Arizona and souther Nevada, my engine sounded like a paint rattle can under load at times and the only cure was to back off the throttle substantially.Normally the ecm is pretty good at sensing spark knock and backing off the timing but it did not seem to help much down south. I dont think my bike liked burning corn fuel.....Maybe try different fuel or as previous poster suggested, some octane booster to see if that helps.
My 2012 bagger has pinged from day one, when accelerating , HD says it is normal, they all do it, and apparently they do from all the bagger owners I have talked with and from reading this thread.
For what it's worth I have a stock 2012 FLSTC, 103ci, with an improved tune ... using premium gas (All 10% blended here) I have not had any pinging since day one. There was no pinging with the stock tune, but it ran hot with the stock tune and is noticeably cooler with an improved (richer) tune.
