I picked up a 84 250R a couple of days ago and the guy I got it from did a rebuild on it 10 years ago. He said that he maybe put 5 hours on it and it has been sitting for the most part unridin ever since. The day I went to look at it he said he hadn't even started it in 6-8 month's. Because of this web site I asked if it had been bored, new ring's, pistons, head work done all that. So here we go. Stock piston with nos Honda rings the cylinder was good so he honed it. The cylinder head was re-cut and shaped the chamber and because of this he said he had to put 2 cylinder head gaskets to get the piston to cylinder head clearance. The thing starts up no problem will pull the wheel off the ground without even going WOT but the problem is the cylinder head gasket is leaking after it gets warmed up. I have never heard of 2 head gaskets being used and will I even be able to get it to seal. Idles fine and I haven't drained the old fuel he had in it which is mixed 20:1. If you watch where the gasket is you can see what look's like oil boiling out. Any suggestions would be very helpful and appreciated.
