Fuel in Exhaust - left prime on

[mbradford99]

If one was to have left the tank on prime by accident, and then went to start the bike a few days later and there was fuel in exhaust pipe, is it safe to assume that the oil in engine has also been compromised ?

The oil level when checking does not look at all higher (or not significantly), but I'm sure it doesn't take much to foul the oil.

anyone know how to check ? or is the next best step to not start or ride bike until draining and changing filter ?

how different is a little fuel in oil as opposed to seafoam or star-tron ?

thanks ...

change the oil

Also pull the spark plugs and make sure the cylinders are dry before cranking. If the fuel got to the exhaust it had to have filled a cylinder. If you try cranking it with a cylinder than it full you risk bending a rod.

I'm not sure that 'compromised' is the proper word.

I would look for something more like 'contaminated', 'fouled', 'ruined', 'destroyed' or something similar.


One possible good point, though, if your float valves are in good condition, they might have held back the gas. After all, that's their job.
The vacuum petcock is just there so the float valves don't have to work full-time, just when the bike is running.
