I have a 2003 Busa. I have a set of yoshimura rs3 race baffle bolt ons on it with a power commander pcIII usb and a k and n air filter. Now the problem I have ran into lately is that my bike has begun backfiring rather violently at times. It only seems to do it when I am on hard acceleration and just let the throttle all the way back. When it is winding down and gets to around 5,000 rpms to 4,000 it will backfire really loud once most of the times but sometimes 2 or 3 pops on the way down. Now it only seemed to start doing this when it started getting really hot and humid around here. I am thinking that what is causing the problem is the hot thin air is not giving the engine as much as it needs which is causing the bike to run rich. I have a map that I downloaded off power commanders website for my particular mods. Now I am wondering if you guys have any suggestions on how to fix this cuz I have never really experienced this problem before. I am kinda worried that it may be harmfull to my bike and wanna get it fixed. Any and all help is appreciated. Specially from Johnny cheese cuz u seem to be the man with power commanders.
