Sxr500 problem

I'm getting gas into the oil injection resevoir on my 2001 Yamaha.
About a week ago I was running for home when the sled quit on me, it refired after a minute or two but I shut it down and we towed it.
So far what I've been able to establish is the left jug is slightly less from a compression standpoint. The cylinder walls don't appear scored but I wonder if I could have burnt the rings, and why the gas in the oil to begin?
Also, I had the top end done about a hundred and fifty miles ago.
