you mentioned it being down on power? If you weren't able to get into upper rev range to clean it out there could be residual 2 stroke oil residue left on crank- maybe that is what you are seeing after it sat for a while? Didn't mention if you are premixing or not and what 2T oil running, but if lower end was really heating up it could certainly discolor your oil residue like that.

The bike would rev clean all the way to 9000. New it was 64hp on the dyno. Felt more like 50. Ran ok. Just not what it was. Plugs perfect color.
Chuck moved the timing jets changed pipes. I thought maybe it's me. 5 seconds on Chuck's bike nope. Bike is down on power. It was originally very close to his in power.
Yes premix only. This ring seems to make sense causing some blow by.
I'll find out next weekend.
