96 Vulcan 800 classic gas mixed with oil blue smoke coming from exhaust oil running out of exhaust manifolds

Gas mixed with oil? Not on purpose I hope as the Vulcan's ran on straight gas.
If you're getting oil from the bottom end into the cylinders it will probablt be from either the piston rings or the valve stems. Either way, it's fairly major maintenance that most people rely on a shop to take care of. Personally, I would. I had a '95 Vulcan 750. Excellent bike but a bit small for me.

I have 750 Vulcan that will not start when warms up

Does the check engine light come on? That behaviour is normally caused by the camshaft sensor.

Pilot lights but won't stay on in my older style vulcan space heater. thermo couple was replaced last year.any ideas that i could try thanks

Most common cause of pilot light problems is air movement. If your space heater exhausts gas through the roof, ensure the cap is on and level. If not, outside air movement will blow out the pilot. If you do not have an exhaust gas duct, check that the unit is positioned so that it does not blow air back onto itself from walls, furniture, etc, and ensure no other devices that move air are aimed towards the unit. The unit also needs to be placed away from central ducting, including return vents.

Hope this helps!

I have a 94 kawasaki vulcan 750 that ran out of gas. after i filled it, it started running rough and would die when idleing. i added sea foam to the gas because i thought it would clean whatever was in the...

sometimes if you run out of fuel it can **** all the **** into the fuel filter causing slight fuel starvation making the engine run hotter as believe it or not fuel also has some cooling and lubing effects on your engine thus giving you sone smoke out of your exhaust as it's trying to burn off the carbon in your tailpipe.
Know it's a long shot but it may just be this.

Hope this helps

Smells like gas and when i press on the gas it putters. white smoke coming out of exhaust

White smoke is usually a sign of head gasket problems.Gas smell could be the unburnt fuel from the cylinder head which is the source of the problem.

Wow , its been a while since I have seen one of those.
The carbs have to be calibrated on those. To insure same airflow and so on. But as I remember the rear cylinder does run a little hotter on those, seems it doesn't get the air that the front one gets. And over time it runs a little hotter. The v45 and the 700 Vulcan had the same trouble in those years.
