Hey folks, haven't even had a chance to do a proper intro before asking for advice. Kinda bummed so I'll just jump right into it. I bought this bike a week ago today and have put about 400 miles on it, mostly highway travelling to work. Haven't noticed any major oil usage, haven't seen smoke or oil seeping around the cylinder head.
Today on the way home, shortly after stopping for gas the bike died on the highway. Coasted off the road and started checking it out. When I checked the oil there was no oil on the stick. So I pushed it to the station(died just a few feet from exit ramp) and topped of the oil and let the bike cool down for a while. Saw some oil around the left side of cylinder head in several areas.
After a while the bike started right up and I rode the rest of the way home, about 10 miles. Once I got off the highway I started seeing smoke and by the time I got into the carport it was like a freaking smoke machine.
So I'm sure a top end rebuild is going to be in order. I can handle the work, just not real knowledgeable about specifics on this particular bike. Does anyone here have any advice, things I should be looking for? I'm figuring it's either a blown head gasket or shot piston ring. I won' be able to tear it down until Friday to see just how bad the damage is. I know I probably made it worse riding the bike home, but I didn't have much other choice. I just hope I haven't screwed the cylinder up to bad.
Thanks for any help.
Oh, almost forgot, here is what the PO has done to the bike. May or may not be useful.

all new gaskets and seals
