I recently bought an 02 Warrior. Bub Chambermaids, Churchkeys V Bak, and I think that's it. I backfires every so often, but on take off it kind of misses like it's not getting enough fuel down in low RPM's. I also think it's running really hot. It makes the crackling sound really bad after running for an hour or so when turned off. What does this mean? I have a PCIII for it, I just haven't had it installed yet. Will this solve all my problems and make the bike run like the beast it is? Also how much do dealers typically charge to install a PCIII. Thanks for anyonese help.
