Fuel Shutoff Valve (petcock)
01/30/08 at 19:45:02

I have an '03 LS650, bought about 3 weeks ago. Anyhow, I am having a problem with the fuel shutoff valve; I turn it to the OFF position (to the right), but the fuel doesn't seem to shutoff (I can run the bike fine with it in the OFF position, have rode up to 20 miles before turning the bike off on my own). Just curious if this means I have a bad petcock, and what the risks are for having it on continuously. If it is a bad situation, how hard is it to replace that valve? I have looked in the Clymer manual, but it says very little about the subject. Any help is highly appreciated!

Ian

RES, ON and PRI ..... no OFF. There is a vacuum hose on the back that acts as the switch. Turn off bike, vacuum goes away, the spring pushes the valve close.

Yeah, there isn't an OFF sign on it... I just figured when you had it in the position that should be OFF, it wouldn't allow any fuel through at all. I am relating this to the Honda Rebel I had during last summer... when you switched the petcock to OFF, it really meant OFF! I know I had forgotten to turn it ON a couple of times before taking off, and let me tell you, it was a surprise after going about a half mile and the bike just cutting off on me! Shocked

Hey Ian, welcome to the club.

First, you should get a couple of manuals, the owners manual shows the basic operation of various features of the bike, such as the petcork aka fuel shutoff valve.

There isn't an off position because it is operated by vacuum. I.E. when the engine is on so is the valve. when it's off so is the valve. the normal position of the lever is straight down.

Mine leaks abit even when off, but it hasn't caused a problem yet but I'm keeping an eye on it.

The second manual (or third) is the clymer's or suzuki shop manual (SSM for short). There's a link somewhere on site posted just last week regarding a electronic copy at a library that can be acessed online.

Thanks verslagen and Mack! I didn't get an owners manual with the bike; I bought a Clymer 1986-2004 manual and couldn't find the info for it.

One question though... when I am not using the bike, should I have the fuel valve in the straight up and down position, or should I have it to the right (what I consider off, opposite from the Reserve)?

I am going to put it straight down. So, to prime it, you just switch it to the right (opposite of the reserve setting)? I will look for a owners manual on eBay. If you know of a site that has an online owner's manual, I would appreciate the link. Thanks! Ian

You've got to read the petc0ck. They are all different and besides, since when was there a rule that "to the right" is off?

Since I know the previous owner wasn't kind enough to give you the owners manual with the bike (they always keep them), go ahead and order a Clymer manual and one of my CDs. I have lots of petc0ck pictures for you to look at Tongue

Greetings from the great White North, man its cold here today, Minus 20C. Can't wait for summer, Anyway....

Came across this site while searching for info on my Tracker 4X4.
http://www.bedlib.org/ebsco.html
The site is the Bedford Library and has numerous online manuals including the savage
when you enter the site, click on "auto repair reference center"
it will ask you for a User ID: library
Password is: library
Go to the "small engine repair Reference Center"
and your in, you will see the "motorcycle icon" for the motorcycle repair manuals.

Hope this is of use to someone

Cheers

It is broken down into sections by a Librarian, so sometimes it refers to a picture or page not in that download, but with detective work the information is there. Wink
