Tune help- TTS,13 FLTRU w naked intake
Hi all. I'm getting pinging at steady cruise anywhere from 55mph to 80mph with the slightest uphill or head wind. I pulled a flight recording, and the front cyl pulls about 1.5* when MAP starts climbing above 55kph. The rear cyl pulls up to 10* (average 4.5*) when the MAP gets up to 65-70kph at 3000rpm. I was just going to pull a couple degrees starting at 2500rpm above 55kph, but I'm nervous about doing it without checking first.
PS: IT DID THIS RIGHT FROM THE FACTORY, IT IS NOT THE TUNER.
Doc is always willing to help, but I feel bad asking. Even though I've purchased two tuners from him; he makes a living tuning bikes in his shop, not over the phone.
Does anyone have a map for a stock 13 FLTRU with a V&H naked intake that doesn't ping.
