Ignition igniters, defo. I had mine dyno'd last year 42 bhp but also running rich. I raced it like this untill I tried a new set of igniters. What a difference!! The old ones were not advancing. Also one had black potting and one had blue potting.

Some peeps are using the DP AL9000 units.

I thought it looked quite nice with all the blue and red lines and stuf, is it that bad? the bloke in the garage said it was o.k. (but he was a bit strange) not very helpfull.

The Clue is in the bottom Graph, Upper Air/fuel and lower A/f limit Idealy you need to carburate between these lines
Your fueling is spot on at 6000 rpm and 8000 RPM thats it, too rich and too lean everywhere else.

Very rich bottom end bradders..... 13 parts air to 1 part fuel should be about right for a racebike at one point its down to 10 parts air to 1 part fuel, so very rich

thanks, I did a track day at brands, and it rides beautifully, It felt quicker than I thought it would and it corners so fast you don't use the brakes much, but they feel pretty good too, so we'll see........

did i mention i'm new to all this nonsence?
