I bought my first Harley and had a Stage 2 upgrade (cams, high flow pipes and air filter), done at 1000 miles. Now I'm at 2800 miles. I have learned that once my motorcycle warms up I'm having preignition issues when I'm throttling up. Sometimes it sounds like small nuts in a metal cup, sometimes it sounds like one nut thrown into a metal cup. Sometimes the sound is really intense. Anyway, I took it to my purchase dealer and they were unable to resolve the problem, reason being that they do not have a dynotuner. So, now I am heading to another Harley dealer with a dynotuner who might be able to take care of it.
Preignition is happening pretty much when I accelerate through a RPM range as it is intense. It almost sounds like a very small amount of preignition is happening when I ride at any RPM.
I'm kind of nervous about this.
My questions are:
How much preignition is acceptable,
and,
At what point does a preignition issue damage the engine?
I use premium gas, 91- 93 octane, usually top tier.
