Gas in the crankcase

[Anonymous]

My crankcase was so full of gasoline that it was weeping out the clutch pushrod hole!
I drained the crankcase and removed the oil filter and plan to let it sit for a day to make sure it all drains out.
The question is, how did all that gas get in there???
Have I got something hooked up all kerwackie?
Thanks in advance.

It seems your float jets are faulty. Also could be the rubber o-ring that holds the needle jets in. Make sure you take a look at the petcock also as it must not be shutting off correctly.

Re: Gas in the crankcase

Your petcock is faulty and must be replaced or rebuilt. Even if your float needles were leaking and allowing fuel to seep past, they could not do so if the petcock was shutting off fuel as there would be no flow to start with.
Its probable the fuel is getting into the crankcase through the vacuum line on the petcock and a leaking diaphram.

I'm not that familiar with your particular bike, but before you rip into your petcock, seems like a good idea to ask -- was the petcock left on prime?

change out your petcock or replace the diaphragm on it. If your petcock has no diaphragm make sure it is off when you aren't riding it.
