I don’t know if any of you have experienced this or not, but I figure maybe one of you can come up with an answer to my FI dilemma.
I purchased my 09 FZ1 on Halloween night of 09. I picked it up the next morning. The bike ran okay on the way home. Since I had no experience of the Gen II FZ1 so everything seemed normal. I rode it back and forth to work for about a month and noticed that it had a slight hesitation down low and a rather obnoxious flat spot anytime you closed the throttle and then reopened it. This was really noticeable around town and even scary when rounding a corner. If you dropped the throttle heading into a corner it would hesitate abruptly exiting. This would cause such a jerk I though the tire would break loose mid corner.
I purchased a PCIII, Akrapovic slip on, and K&N filter. I downloaded the PCIII calibration from their website for an FZ1 with slip on & filter upgrade. I installed all three on the same day with the help of my buddy. The bike ran pretty much the same as above and I learned to drive around the flat spot & hesitation the best I could.
One day I was riding home thinking about what I could do to the calibration to fix these issues. Aside from a full on dyno session, I figured maybe I would download the acceleration pump software from Dyno Jet, maybe a different calibration, just thinking, just wondering.
Three weeks ago, my usual ride to work started off as normal as ever. Gear up, roll the bike out, start, and warm it up a little while putting on earplugs and helmet. Hop on and start the commute. The bike is running totally different. Smooth as silk, no hesitation, no flat spot, absolutely perfect. A caged animal with the door left unlocked. It was awesome!
I talked to some of my buddies at work, the computer guys, and they seemed to think it was a sensor issue or connector issue. Since firmware and software can’t really change on it’s own they felt it must be mechanical.
With the bike still running perfect all week, I pulled it apart on the weekend and disconnected the PCIII and slathered some dielectric grease on both connectors. The bike is still running like a raped ape so I don’t want to mess with anything else. On of the guy said the TPS, because of the flat spot when the throttle was closed and then reopened, could be the culprit.
I don’t want to take it to the stealer, I mean dealer, because I’m not confident in their ability to diagnose the problem. I don’t know if they can even test for sensor failure or not. I know you can do diagnostics on cars through the OBD port but I don’t think bikes have these yet. Or do they?
Any thoughts guys? I’m at a loss here.
