2007 zx14, muzzy full system, stock air cleaner, pc3 with muzzy map, ran like a bat out of hell, but had the crappy low end performanc, so after much consideration decided to remove the flies...i aslso removed perferrated steel plate from the air cleaner and loaded in muzzys no fly map. Took it for a ride and it totally sucked!! way lean. Even the speedo and tach seemed out of whack! I didn't think that the map file was corrupted or the air cleaner mesh plate could make it this lean. Now the nightmare gets even worse, i put the flies back in and loaded the original map, now i get the error code (F I) and i can hear the gears grinding on the secondary shaft! I disconnected my pc3, and went back to stock, same problem ! ican't find no info on codes the code is 62!!!! I am super pissed and disgusted!1 has anyone encountered this problem, i have been building bikes for 15 years, i refuse to take this to the dealslership.
