Are you running premium in the bike, have you tried a different brand of fuel? Is there an ignition advancer installed. FWIW, I've always ran premium in the bike. The few times I experienced pinging was when running mid or low grade fuel after installation of the ign advancer. I believe running too lean can cause pinging as well. In the 11 years I had the bike, the only fuel change was FACTORY brand needles. All the jets were original at 80K miles.
I don't think 3800 rpm is lugging the engine, it is a transitional rpm.
