Help!! Smoking exhaust and dying Engine

I need some help before I spend a few hours trying to fix my bike. I have a '94 VN750 and recently my bike will spontaneously die out in the middle of riding it. It slowly loses power and feels like it's choking out, then dies. It will restart and ride fine for 10-15 minutes before doing it again.

The last time I rode it, I could feel one of the cylinders lagging for a few seconds, then it would pick up and my rpm's would shoot up and the bike would accelerate suddenly. After a couple minutes of this happening, the bike died out. I started the bike up a few more times to try to figure out what was going on, and white smoke came out of the exhaust each time. I've worked on cars before, but never bikes and am looking to any advice before I rip the bike apart. I'm thinking it might be the head gasket and/or piston rings are worn? Any advice would be much appreciated. Thanks guys.

Thanks a bunch. I just read a bunch of other articles about possible problems and fixes. Sounds like I'll have to find some time on Saturday and a case of beer and get to work!

Could be flooding, raw fuel out the pipes. It happens with these bikes, usually with a stuck float in the carb. A lot of the description reads that way, but you should start to see some black smoke when it bogs while running.

Need to get a whiff of the white smoke, antifreeze or gas?
