hey all i have a problem which seems to be getting worse and louder............when i am mainly at mid to high speeds and i twist the throttle (hard) my bike pings and cracks...it has done this for a while. when i first got the bike it had a stage 2 down load and it did this mildly..installed a pc3 and it became louder........now as time goes by she is getting worse...i am thinking it might not be related to the pc3 which has been dynoed.........i also noticed last night around third gear(mid range) she has lost some pep......i am in savannah ga and i really dont want tp bring my ride to those shoe makers so my next option is to bring my bike down to a harley in fla..........please help if any ideas

 

Sounds like a timing or pinging issue.

 

It sounds like it running too lean now With the timing and the fuel delivery changes. Also, have you switched fuel brands, stations?
