yes some more info from me proably would have help sorry guys the bike has stage 1 k&n air filter with power commander and a set of aftermarket pipe that look like stock one idk the brand all of this was on the bike when i bought it before i ever put one mile on it i took the bike to my local harley dealer and they went threw the hole bike and said all was well they put it on the dyno too 71 hp's at the wheel and 80 something foot pounds torque and yes this is a new thing that just started happening so what is the min octane rating for this motor
krazy8s it sounds like we have/had similer problem maybe the motor is pinging but i don't think im hitting the rev limiter this all happens around 2000 to 3000ish rpm's

Octane should be as high as you can get in your area, I use 93.

that puts a whole new spin on things 
Seems a bit weird to me that you are only getting 71/80 out of a stage 1.... again, I am no expert, but these numbers seem only marginally better than stock. Might be an idea to contact Jamie at fuel moto to get his opinion on it. Still sounds like pinging to me, but if a stage one is done and this just came up then there could be a whole different set of issues going on here. It could be as simple as the PC needing to be better mapped, or something entirely different.
Over to those who have vastly more knowledge than i do.....

ok so i will start using better gas and not hammer on it in the upper gears with low rpm's maybe thats all it is then when the rpm's get up over 3k the noise gose away im a meat head this is simple riding 101 i thought the fact that these motors made peak hp's at like 3200 rpm's i just figured they liked running low

took the bike out for a ride last night and changed the way i rode the bike made sure the rpm's stayed around 3k and the lazer/pinging sound went away it only did it once when i was gettting on it in 5th gear around 4k rpm's so i think some better gas should take care of that
