1995 Enfield Bullet 500 Part II

I was able to make some time to look at the Enfield today. I took off the head and cylinder and descovered what the problem is.
The pictures speak for themselves:

 

I must say I am happy that it isn't the connecting rod, 'cause those are pretty expensive (although I don't know the price for a new piston yet). The downside is that the lower piston ring is completely in small pieces, down into the crankcase, meaning that I have to open the whole thing up and clean it out.

More to come ...
