Suggest if have the service manual to try the troubleshooting guide under the appendix section.

On the fault code find, worth a check under sect 3-38 fuel system (DFI) self-diagnosis. Mind mine the MK1 but MK2 should not be far off. Good luck... :028:



This is a bloody great Bike....!

 +1 to Seafoam or other fuel line de icer. I had a similar problem on my V 650 and a shot of methyl hydrate cleared it up immediately. Water in the fuel getting sucked up to the filter as demand increased with more throttle. The problem never recurred.

thank you sir, I've just been out and tried the diagnostic , but because there's no warning lights showing when the engine is running it thinks there's nothing wrong so wont go into diagnostic mode. still have a misfire when starting and ticking over. might have a ride out on it tomorrow while the new plugs arrive, then i'll lift the tank and check the connectors and fit the plugs. i'll also get some seafome or similar, all I've got is redex, might give that a try, It will at least clean the injectors.

Most welcome, sir  :002:

Very likely it is some water condensed in the tank. Water finding paste will have a change of color if water is present. (http://www.kolorkut.co.uk/). Water being denser will settle at the bottom of the tank.

Agree your action plan is worth a shot :028:

Just spent 2 hrs in my workshop from start to finish,
Fitted new sparkplugs, everything looked ok , all connectors were clean and dry,

Took 5 mins to get the tank into this position, no need to remove the fairing, just the side panel/fairing part on each side of the tank.





Gave the k & n filter a clean and oil


Stick coils were a pig to get out, just stuck on the rubbers, did them one at a time and blew the holes out before removing the plug, no dirt or water came out.
 Usual staining but nothing I've not seen before



Number 1 was a pig to get out because the wiring harness runs across the top of the coil. Out of interest, what's the spare connection in the harness for, just above my finger



All plugs looked ok





All back together, started it up and it ran instantly on 4 cylinders, before it fired on maybe 3 for a second or 2 then onto 4, this happened each time I started it.
Its like winter here at the moment so I'm not going out on it but it feels ok again. Hopefully it's a better day tomorrow and I can make sure it's running as good as it always has.
Happy days.

managed to get out on the bike today, done about 50 miles and the misfire has gone, all I can put it down to was a spark plug deciding to throw the towel in, Id have expected them to last more than 9,500 miles so maybe just a duff one. Anyhow its all back to its lovely smooth throttle etc etc. Happy days.

You're right of course.. 9,500 miles for a plug isn't realistic today.... but, every so often a duff plug will show up

Good to hear that your bike is now back to its best  :169:
