Yo. So I'm hoping some of my OR peeps might be able to help me out. Bike: 2007 ZX6R Full Leo Vince exhaust (actually Leo slip on with Pine Box header) Bazzaz Fi unit BMC race air filter Jumper Mod Custom Map I was racing Sunday at Nelson Ledges when my bike started having issues in practice. It would pull hard, like normal, in the lower rpm range up until about 12 grand. I noticed it coming out of a turn in 3rd gear and pinning the throttle. Once it got to about 12000 rpm, where normally the power really comes on hard, nothing would happen. The bike would just very slowly climb the revs and be extremely underpowered. It would also hesitate or stutter ever so slightly periodically all the way to redline. It would do this in every gear after about 12 grand or so. So needless to say my races were fucked as people would just blitz me on the straights. After my first race, we drained the gas and put in new gas from a different source. We also checked the connections on the Bazzaz unit, and unplugged it and plugged it back in. Went back out, no change. We switched the Bazzaz to a secondary map. Nothing. Then we completely removed the Bazzaz unit and wire harness and hooked everything back up stock. No change. We checked the fuses, they look fine. Fuel pump is coming on like it should. I don't know, any ideas? I have a race in a few weeks and would definitely rather not waste money taking it in somewhere. Let me know what you guys think. Thanks, it's much appreciated.
