compression lock?

[Guest]

Hey everyone i have a question that seems to have not been answered alot.
I have a 1980 gs 1000g that seemingly runs fine all but a slight tapping sound coming from the
Right side of the engine. Anyways i been having a problem with gas coming out of my airbox and its just a little bit. I only realize it the next morning after riding it. And while this is happening my bike seems to be flooding i would say. When i press the starter and hold it like you would NORMALLY sometimes it would just stop turning over and make a hissing sound like a leak coming from somewhere.(sound like from spark plugs). After i push the starter a couple of times(like 2 or 3) it would turn over fine.
Any suggestions and i apologize for the book.

Time to check your petcock- gas leaking out airbox means problems!

Yes...that could be a sign of HYDROLOCK. I would take the carbs off and visually verify the float needles rise and fall freely and reliably. Also while they are off, reverify the float heights..sure to measure without the bowl gasket there.

Yep, your cylinders are filling with gas due to your petcock and carbs leaking, which causes hydrolock. I'd be real careful, in extreme cases you can actually bend a connecting rod from this.

I would change the oil too before restarting the engine.

This. 750 had this problem when I bought it. I bought a new petcock.

i second this. my petcock was leaking and filled my crankcase 2 times before i got everything sorted out.

Gas in your oil is a Baaaaad thing.

Holly crap my engkne oil is super filled. Dammit. But i rebuilt the petcock as in new gaskets as soon as u fit the gaskets on tight and the dont move the lever nothing comes out of the petcock at all but even when the bike is on and running no gas at all. Even stalls because of no gas. But the minute u turn the lever all HELL breaks loose and it doesnt stop flowing no matter where u turn it

Hi,

It's a well-known issue around here that petcock rebuild kits don't work that well. Get a new petcock. Go through the maintenance lists in the "mega-welcome".


Thank you for your indulgence,
