'81 GS 650 fuel shut off

[ticker650]

Just wondering if there is a way to shut the fuel off to the carbs? There is on, prime and reserve. So what do you do when you put the bike away for the winter, aside from draining the tank?
Thanks

Leave it on, put some stabil in the fuel and cover the bike.

Welcome to the site...Basscliff will be along later with the official welcome.

Yea, it was topped up with fuel. No stabil as I figured I would fire it up every couple weeks, but didn't. Bike is indoors, its not hot, but not cold either.

Hi Mr. ticker650,

See the link on my page entitled "Where Do These Hoses Go?" (<<or just click) for an explanation of how the stock vacuum petcock works on these GS bikes. Vacuum actuated petcocks allow fuel to flow only when the engine is running. If the engine is not running, even 'ON' is "off". (The 'PRI' position should be the only position that will allow fuel to flow with the engine off.)

Now let me share some GS lovin'.

I just stopped by to welcome you to the forum in my own, special way.

awesome tip. I had no Idea, I did not find it in the manual thats for sure. I thought I'd be doing some work on it to get it running but no, that solved everything. So with that being said, what does the choke do then?? Might be an ignorant question, sorry

The "choke" on these bikes is actually an enrichment circuit that allows more air into the engine. It helps the engine warm up when cold starting.

ummmmmm... not so much.

It actually adds FUEL, not air. Hence the "enrichment" portion of the equation.

I thought it was both? (maybe I should have said that) You sure its just fuel?

EDIT: My understanding is that it opens a completely separate air passage. Attached to this air passage is a distinct, un-serviceable venturi. The reason I said it allows more air into the engine is because the added fuel is only a side-effect of the added air.

Hi,

From the manual:


To me it sounds like extra fuel being mixed with the normal amount of air.

Thank you for your indulgence,

I guess that will be the thing I learn today. Is it the same with the VM carbs?

Hi,

There's a VM manual on my website too.
