Bike running very rich.

Bike running very rich.
Hey folks below is a pic of my bike on the Dyno at about 8000rpm and as you can see its running very rich and I'm buggered why.
Has after market pipe and K&N both are free flowing and not clogged.
Is running standard jets, which if anything should make it lean with the above.
Float height is correct.
At least the good news is that it still ran 110hp at the rear wheel which is not bad considering its done 107k and has lowish compression.
Any ideas?

RE: Bike running very rich.
Mine has a Dynojet kit, K&N and pipes too, and has always run rich at UNDER 8000, after that it leans out. What has been changed on your bike to make you worry ?
Rather too rich than too lean..........
Is that not also a little oil smoke ? You say the compression's a bit down, and at 107K it may be losing a little past the rings at higher revs, or even build up inside the pipe........which wouldn't show on the dyno........

A bit surpricing if the Dyno faclitiy didn't measured the A/F ratio, or perhaps they did and you know for sure it runs fat at 8K?
If it is not oil smoke, and it looks as to much fuel, you may try removing the needle shim if you are using this. My horse memory tells me you used a shim a couple of years ago. The problem could also depend in worn needles or emulsion tube, this is probably the caseon a bikewith this mileage.
