Engine stopped and puff of smoke from under gas tank

[Guest]

Was out on a long ride yesterday and stopped at a light a few blocks from my house and had the bike in neutral and the engine just died and then a puff of black smoke came out under the gas tank, on the left side.

I did not try to restart the bike, I just pushed it to the curb. There was a smell almost like really old burnt rubber. But she started right up and I rode home no problem. When I got home the exhaust had more white smoke than normal and the small from the engine area was still pretty strong. I was late for an appt and did not have time to look closely while it was hot but I figure I will pull the tank and look closely, externally for anything burnt. Maybe something in the cylinder blew, like a ring? Still seemed to have OK power. I need to do a compression check obviously.

Any ideas on what to try?

Thanks!

Pull the tank.. Sounds like an electrical shortage.

is that like a fuel shortage?
JK Octain I work on computers and a puff of smoke is a fact of life.
electricity is the work of the devil.

I had a burnt rubber smell once when a reg rectifier failed on me

Well, I had just replaced/fabricated and installed a new mounting for my regulator so I better start looking there!

Ha, well, I did just switch to reserve while on the highway. :-)
