Thanks for the responses gents, sorry to keep you waiting, was sending off my first attempt in Vermont for a different machine.
In, out and under and slightly smaller size, never used postimages b4, shiny stuff underneath more sticky than oily, not thick at all.
Thats not oil on the crown topside, just melted aluminium. Yes, likely 45 year old seals, and was actually tires until a few years ago, black and round:) I'll peep the crank phase when I work on it again, R head loose but not off so pretty easy. Unless it moved, It should be where the built it. Seals are always a concern but it exhibited no unusual behavior.
Was running totally well and good until I thought I heard a funny clank(likely the ring down the pipe) and lost a bit of power, was somewhat concerned but my attention was on keeping it between the trees. Generally cover the clutch anyway when going quickly.
There were definately things bashing around, namely the rings, did some nice work on the head as well:) Blame is squarely on me, probably done 4-6k on it.
Very suprised at the lack of damage and that it ran reasonably well for probably 20 miles after the clank. 1 kick bike that morning after sitting probably 7 months, had 50/50 aviation fuel and no ethanol in it with a spash of castor for storage. Tank has not been treated ever and has surface rust so it stays full or empty and fogged.
After the incident and with the piston as you see, was still just a 4 kick bike. Knew something was bad when I found the plug closed up.
Pin was about as tight as they are new, didnt even have to get behind it with a hammer, nice parts Yamaha:)
