Missfire.
Hi guys, hoping someone will be able to help here. Have a B7 14 in standard trim and it's developed a missfire! Seems rough as f*** below 4K and feels like it's dropping a plug, seems to run fine above about 5k. It also occassionaly back-fires, again down low in the revs. It's only done 1500 miles from new and as I said is all but standard. I also noticed the other day that the fuel-bars seemed not to move from 3/4 full, to empty and flashing at me in the blink of an eye. Faulty ECU I am wondering?
Anyone had a similar problem or can you guys shed any light on this.
Any suggestions would be most welcome.
Cheers all.
Blaggie.

Flashing water bars or flashing fuel bars mean code. So, did the fuel bar literally flash at you? Will it do it now you turn the key on engine off?

Hi, thanks for the reply. No, as soon as I filled the tank all the bars showed as tank full. Just as normal!

2007 @ 3 yrs. ~ 36 mo.
1,500 Total Miles.
= 41.666 miles a month.
Run Chevron or Shell for awhile. They use injector type detergents to clean the jet holes. Maybe the gas you just filled with might clean up the stale gas misfire is my guess. Your answer back without flashing bars says no codes.
The drop from 3/4 to empty says you should be smelling gas but you did not mention a gas smell. Did you ever smell gas while riding? This meter cannot drop from 3/4 to empty unless you are moving up there in speed, then you will. Depends on how you mean that one ride from 3/4 to empty can quickly happen. Are you saying you see the 3/4 mark and within the next few seconds she is flashing on a low fuel level like last time? Or does it take 15-25 minutes of hard running seems like a flash? Mine will empty fast from 3/4 to a low bar in that amount of time.
See if that float was hanging as you rode just now, getting stuck and flashed low with that low fuel light on. I doubt that arm was stuck caused by gummy stale gas forming on the fuel pump. Monitor the dash to see if she can duplicate it again, or it could be nothing more than familiarizing yourself with the bike.

Need more info. What mods do the bike have? Pc? Pipe/s?
What happened just before the ill running? Did you just wash it?
Or was it an all of a sudden failure?

Thanks for these replies guys.
Bike has been running rough the last two times out for a ride.
Thought it was the damp and cold weather the first time, around 2-3C and very damp conditions. Second time out was around 6-7C and not at all damp and that's when the fuel-bar incident took place. It literally went from 3/4 full to empty and flashing in the blink of an eye. Have booked bike in at local Kwaka dealer for a diagnostic check so I'm hoping they will be able to figure the problem. As to "had I just washed it"? I'm always washing the bike at this time of year and always do it the same way so I don't think it's water ingress or anything like that? Will post results as soon as she's back from the dealer. Thanks again guys for the help and suggestions.
Blaggie.

P.S. Yes it's only done 1500 odd miles in three years.
Previous owner had 11 ZZR 1400's, (fanatic), and he only put 500 miles on it in 12-months.
Maybe it needs a trip to the South of France and back to clear it's throat!

I would have to agree about the washing. The connectors are weather-pac so the elements say out. If the dealer finds a saved code and that fuel bar incident correlates with the phantom, 'blink of an eye' thing you describe, maybe that might show a way to your drive-ability problem. Could be electrical and not a clogged injector. You never know till you touch a cold pipe or hook up a timing light and see who shuts down first.

bikes are not ducks
I am a 100 percent non-water clean up guy when it comes to my bikes. Just my 02 cents worth. Try taking your air hose an blowing air on all of your controls and connectors,and see if the misfire begins to clear up. I know they are suppose to be water tight,but a little water between connections can cause havoc. Let us know what you find out.

Hi guys, the bikes back from the shop and the missfire was down to fouled plugs. New plugs in and running sweet now. The fuel-bar issue and lack of immobilser warning light was down to a faulty instrument gauge so am waiting for a replacement for that as I write. Looking for PCIII now so I can remove the flies and re-map. Cheers for the help guys.

A sitter. Low miles, short rides, not real hot to blow out the carbon say is more burn the plugs hot enough to keep them clean from fouling. Is this how basically the bike was ridden, blaggie?

Very cool! It's pretty amazing what plugs can do to make a bike run like a POS. I hate it when you install new plugs and the bike runs the same way, then you tear apart and trouble shoot the whole bike only to find nothing! The problem then comes back a faulty new plugs! Another set of new plugs and the bike runs perfect lol! Had that happen at my shop too many times.
