I recently bought a 2005 s2r. It's completely stock except for termi exhausts. I was told that the exhaust w/o a tuned ecu can cause the bike to run lean.
In my experience it seems bikes that run lean don't backfire, but rather too rich of a mixture will cause backfiring.
Could my valves be out of adjustment? Do I need to get a power commander or DP ecu? I've heard the fuel injection on these bikes can be "tuned" by changing the injector pulse timing (mathesis tune?). Would this help?
Thanks!
