Out of my 96 Cr 250 I build 2 years ago. 12.0 hrs on top end. gearbox locked up, cracked left side case... Finally getting around to tearing into it. This is the piston....any thoughts? Cylinder has original plating, just stating to show some wear on the upper exhaust port, nothing showing on the piston exhaust side. Some funny carbon buildup on top of piston, looks like some of the head gasket material, gasket shows signs of coating coming off around the closest edge of top of cylinder. Bike was running great before the trans locked up...
Cylinder may need replating.

Also, (believe it or not), JAF actually has a good TIG welder that they subcontract some work out to. He did a subframe for me last year that got gouged out from airbox and number plate rubbing. Came out terrific for not a lot of money. On par with Rich's work. Definitely a pleasant surprise.
The grayish color on your piston crown with chunk type deposits looks like leaded fuel deposits. I get the same thing with Sunoco Supreme leaded fuel. You're probably using C12
Can't blame you for wanting to wind down the amount of time spent working on bikes. Projects like these take a lot more time and effort than many people realize.
Your last sentence is important. I talked to the guy running ADK on the phone a few weeks ago. He says the Town of Ft Ann is continuing to give him a hard time. I would not be shocked to see him throw in the towel since he's already spent a lot of money on legal fights (sound familiar?). I didn't bother to ask him what his net profit was, but I would not be surprised if it's very low- if he even made money at all. After the devastating losses we've recently endured, this would be yet another big blow.
