Unsure if any of you are following the thread over at the FZ1OA site... But I started having this problem with mine... a 2009 with 600 miles on her now.
Things completed:
Two Bros slip-on (CAT still intact)
EXUP eliminated (See above)
AIS blockoff - Nothing removed, jusy blocked the tube and clamped back to the airbox
LARS airbox mod
De-screened stock air filter
Here's what I've not done anything with to date:
I don't have a PC III (or V), just the stock ECU.
As stated, still have the CAT.
AIS valve and tubes still in place just no more fresh air.
Flies have not been modified or tied.
The issue is when I am just cruising in traffic at a steady 3 - 5K RPM range, the bike will momentarily cut, sputter and surge. These are very slight. If I roll the throttle, the bike works perfectly. If I get below 3k RPMs (very slow in high gear), the bike doesn't "seem" to do anything wrong.
In the other forum, the suggestions were as follows:
1. Wrong map (Nope, I have the stock ECU)
2. O2 Sensor eliminator (Again, stock ECU and O2 Sensor still in use)
3. Fuel or vent lines kinked (I believe this would PREVENT me from rolling on the throttle and having excellent acceleration, correct?) I did check the tubes and was careful about this having come from the FZ6 which is also prone to hose issues after lifting the tank.
4. Electrical connections - loose, dirty, wet, etc. I've not checked and will as soon as I secure a hefty supply of dielectric grease, then I'll go through them all and seal them up.
5. Bad fuel - Again, she accelerates fine and I've tried three different stations, one gets theirs from Sprague, one from Irving and the last from Global so I know it is three different tank farms!
6. Fuel filter in pump clogging - Once more, accelerates fine
7. Dirty injectors - Yup, still accelerates fine!
:surrender: Any thoughts? Ideas? the only two major changes was the TBR can which removed the EXUP and the AIS blockoff. I find it difficult to believe that the LARS and screen removal, letting the bike breathe better, causes this. I did this on the FZ6.
Please start throwing out comments, suggestions etc... I'm about to return the bike to stock to see if the problem stays or goes.
Tonight, I've disconnected the battery and will reconnect it tomorrow. I know it's only 30 seconds to clear the ECU but I just don't feel like going back outside to the garage (raining.... AGAIN!)
Tomorrow, I'll be going to the store to get the grease among other items... I'll work on the connections Thursday.
She's a great bike but this is starting to annoy me on a brand new bike. It appears in the other forum that is is all GEN II bikes with a vast array of mods and even a couple very close to stock. This isn't a show stopper but I'm having doubts about modding this beast at this point.
