Hi All,
This is my first post, I'm new to the forum.
Desperate for advice please.
I have a 2007 FZ6 S2 Fazer, 23k miles, completely stock except for K&N.
Had the bike 2 years from 10k miles and it's been a dream until about a month ago.
As soon as it comes out the other side of the familiar mid range flat spot, right when you're expecting that lovely power from 10k onwards, at anything over half throttle it just lurches all over the place and cannot redline anymore.
Otherwise, idles as they do, low to mid rpm as they are, returns high 50's to low 60's mpg, starts on the button, no complaints.
But now it's no fun whatsoever and I'm gutted.
Today I had the plugs out and they were all in good condition and I just nipped the gaps down to spec. Except for cylinder 4 which was rusty around the seat and the washer. I assumed a water leak past the coil boot and the plug was also quite loose, so I cleaned up the sealing surfaces and put back in.
Started and ran smoother, but still this rubbish situation high up.
I had hoped it was that plug causing that cylinder to lose compression, but obviously not.
Really don't know where to go next.
Any ideas, at my temper's end with her at the moment.
Thanks,
Simon
