fuel injection problem.......

[Deleted]

hi all took the bike out for a blast today and got involved in a bit of a race with a bmw m3. this of course was on a private road (i think) anyway when i got to 130 the bike had had enough and started missing this hasn't happened before and when i slowed down to 80 put it in fourth and accelerated it was having none of it so i decided to pull in. the FI light came on and it was revvin freely standing still so i set of again and it was fine still with the FI light on then strangely the light went OFF and i lost power again. now it seems that when the light is ON the bike runs as normal but when the light is OFF it's fookin shite. it's an 05 model with 3800 miles so hasn't even had it's 4000 mile service yet.
any help is much appreciated!!!!
oh by the way the bike still runs all the time but wont accelerate hard if it doesn't want to.

First off is the bike standard mate?

no i've done the air-box mod, got campbell sidewinders and it has a power commander . but this has all been done for over a year now and it's never played up until now. i've also altered the gearing but i cant see that being a problem...

Hmm the fireblade guys talk about having the ECU reset but this is a subject of much debate, some argue it can go into safety mode if the bike hasn't been ridden hard or has been sitting for as little as 4 weeks

Other most common solutions include changing plugs and cleaning or replacing air filter

There is a similiar problem with the odd 08 GSXR600 between 4 - 5000 revs which dealers can't explain and expect a recall

Pain in the arse though

Hi Guys

sounds like a fuel pump problem to me

(or a blocked Fuel cap vent) custom fuel cap?
ie all the billet caps on Ebay have no vent so don't work properly on the Z as it needs a vented fuel cap (why it whistles)

have had similar with mine and it was a wire trapped under right side frame cover (rubbed through insulation).

Regards
