Brand new petcock experience?

[BigD_83]

I would like to put some feelers out there for people's experiences with brand new, Suzuki Genuine Parts petcocks. Skip to the end if you just want to see the question.

The background:

My petcock seized in the fall and I ordered and received a brand new SGP petcock in December. I got around to installing it a couple of weeks ago and managed to get the 650G out for a few short rides to see how things were going. So far so good on the mechanical side of things.

Last night, after a short ride (~15 miles) out to work and back home to warm up the bike, I started getting set up to do a highest idle adjustment and carb synch since it needed it with the new BUB header. As I worked my way around to the right side carbs I happened to glance down at the oil sight glass, and it was overfull. I had purposely left it just a hair below full when I changed the oil last time to be able to monitor the situation. The oil is not convincingly gassy smelling, but definitely higher in volume than before I rode.

Summary: bike on centre stand, engine still hot, sight glass says oil overfull, no huge smell of gas, All 4 plugs show lean, exhaust smells rich, a little white smoke from the muffler

I pulled the vacuum line first, and a little bit of gasoline dripped out from the nipple and the end of the hose. Not a lot, but more than I would expect from a BRAND NEW petcock.

As it turns out, because I waited more than 90 days to install it, and it was not installed by a Suzuki mechanic, the warranty is void. Live and learn on that one. I guess planning for the future is not in the service manual.

I don't need to go over the routine of failed petcock as there are plenty of threads on the problem, and I've "been there, done that", but

How many people have ordered a SGP petcock to have it fail?

That stinks- I got one from a FLorida guy ( I hope georgefix sends me disneyworld passes for all this hype ) for $45 delivered. Exact copy of my original, but RES kicks in at lower level. Did this new one look exactly like old one- maybe suzuki dealers are rebuilding them to generate business!

I've never ordered a new one, my 1100 cock works fine, but I went into the rebuilding mode for my '79 GS1000E petcock, since a new one of those goes for $263 and change at Boulevard Suzuki . I would think if I spent that much for a failed new petcock, I'd be rather irate!

$263 at Boulevard? Are the 1100 petcocks made of gold?

I'm happy to say that it didn't cost me that much, as I took advantage of some deep discounting from Boulevard during the December sale, but factor in the oil change, new filter, time, and worry...and it becomes more of a headache than I'd like to deal with when I'm supposed to be doing a long ride with a bunch of GSers this Saturday.

That bike has issues. That is a whole lot of gas being dumped into the #2 cylinder.

I don't think mine is that bad, but I'll know more when I get the clear line on it tonight.

I got mine for the 850 about two years ago from Z1. Not sure who makes it but it's working just like it's supposed to.
Trying to avoid buying one for the 78 1k.

No, I didn't have a problem with my 1100 petcock, that price is for the
'78, '79 GS1000E petcock, and thats a steep discount over retail which I believe is around $311.

I have a brand new OEM one in a box.. for my 850 For some day when I need it.. ON SALE BikeBandit

[TheCafeKid]

Couple things:
One, not to suggest you're jumping to conclusions or anything, but you're sure that the petcock dribbled and not just had some gas up in the spout that dribbled out? When you remove the fuel line they'll dribble a tad sometimes.

Two, for the later style petcocks, the product Z1 carries as replacement IS exact OEM. Not OEM replacement, but genuine OEM same petcocks different box than Suzuki put it in. Made in the same factory etc etc. So I wouldn't spend any extra on a "SUZUKI" or "SGP" labeled box. The same cannot be said for the earlier models with the big lever however, and I've yet to find a suitable replacement for those. However, if you shop a little, you will find a couple of things. Kawasaki used the same petcocks on a few models.. If you go to Babbitts or bike Bandit or whatever, and look at the Kaw version, it's often times more expensive than the GS version..although there is nothing different. I know that some of the early 80s XS twins used the same petcock with the same bolt spacing as well (for instance the 81 XS400) and can be cheaper still than the Zook version. Off the same online supply house no less..!

Anyway, if indeed your petcock has failed already, I'm sorry. That truly sucks a big one.

Looks like I am better off buying it from Z1 for my 80 850G. sorry for your bad luck!

[Dogma]

I've replaced the petcock on both my GSs (one from PartShark, another from Z1, I think). Neither box marked SGP. Both have been flawless.

Josh is right that the fuel nipple will dribble a bit when you take the hose off. I've never seen that on the vacuum line.

I think if I was in your shoes I'd leave the vacuum line off for a while and see if any drips form, just to confirm the diagnosis. Dissasembly and inspection would follow any further drips. If you have a simple defective diaphragm, then a rebuild kit seems to be in order.

BigD_83, tnx
I belive i have to check this petcock again(with a vacuum pump) like tkent02 adviced some years ago. The bike have not run very much since then ..

That stinks- I got one from a FLorida guy ( I hope georgefix sends me disneyworld passes for all this hype ) for $45 delivered. Exact copy of my original, but RES kicks in at lower level. Did this new one look exactly like old one- maybe suzuki dealers are rebuilding them to generate business!

Same here. And fast shipping.

Tom,

The new petcock is an exact OEM replacement petcock direct from Suzuki, AFAIK.

Frankly, I didn't pay attention to where the intake was for the reserve.
