That white powder means its way to lean correct??? I just installed the Dynojet kit last night after previously trying to go up 2 sizes each on the mains but after a run my plugs ground strap had a white powder and the rest of the plug looked brand new. I installed the 146/148 mains from the dynojet kit and have a GYT-R Slip-on and Pro Design filter setup. I'm hopeing this will be a tad rich and I will add airbox vents to fine tune the jetting.

It sounds lean to me too. But it could be the fuel. Try some different fuel after cleaning the plug off. Dynojet kits are not always going to be just right for all bikes. Different stages of modifications and altitude make a huge diffenece in carb tuning. My 2 cents

 

I havent checked the plug after installing the dynojet kit. I went up 2 sizes with factory jets. I'm going out in an hour or so to see how she's running.
