Mods that would matter are 48/170 jets, FMF titanium pipe w/mid pipe, !grey wire and YZ426 tank).

The old plug was black - very black. It was a couple months of Sunday riding old so I wouldn't expect it to die so quickly. I noticed when twisting the throttle on the stand that a puff of black smoke would come out at the first hit of the throttle. I've never noticed this before and from the plug and this I know it's running rich now. Before the grey wire mod it was running just right. I wouldn't think the timing would affect my mixture like this - could there be something else I'm overlooking? Perhaps with the timing advanced it doesn't burn all the feul as quickly? Perhaps I got some bad fuel?

I used to have your problem from time to time and now I start the bike, count to 10 and shut off the choke, let it warm a bit and then circle the block. When I'm half way around, I shut off the fuel, roll into the garage and let it idle until the fuel runs out.
Never had the problem since.

Is there any chance that advancing the timing via the grey wire mod and not advancing my exhaust cam has created some situation where the mixture is unable to burn completely? And lastly, should I just put the grey wire back and call it quits or should I start fooling around with my jetting to lean it out?
