929 started pinging, any ideas why?
2000 929, full Erion exhaust and a power commander. The bike has about 25k miles on it. Changed the plugs and checked the valves about 3 months ago. Recently the bike has started pinging if you roll on the throttle in the lower rpm's. I'm not sure if it does its still happening in the higher rpm's because i wouldnt be able to hear it. The fuel economy has gone up just a little bit recently too for no apparent reason. I've also gone through about 4 tanks of gas from different stations with no change. Always ran premium. Anything i could check?
