I just broke down and bought me  a new stock petcock. I didn't have any issues  when riding, just a little inconsistent idle and having to switch to reserve after 1.8 gallons instead of 2 gallons like it used to. The screen on the old one was clean, so I suspect the diaphragm must have been a little stiff. I dunno. We'll see how it is with the new one. Besides that it was almost impossible anymore to turn the lever without pliers. The new one is all easy and smooth. We'll see for how long.

That's enough! I'm going with 1/2" delcotranslux reinforced hose with a stainless manual ball valve with a red lever that says "STOP" and "GO". And I'll use 93 octane which is harder to light in a wreck.

Well, we now have over twice as many folks reporting as last time I ran the numbers (and Babyhog forgot to click that she had a petcock failure although she reports one in the text and did list that she got a Raptor -- the numbers are off adding back up correctly by one now)

With Babyhog not reporting her petcock failure on the main 2 responses, we have 38.23% having had a petcock issue.   If she had clicked correctly, it would be 39.70%.

So we are still hanging close to 38-40% having had a petcock related failure and the total numbers reporting now are 68 (edging up on 100) and the petcock failure percentage has hung pretty good all along at close to 40%.

The vast majority are from bikes 10 years or younger (still surprises me, that)

Also, the sheer number of Raptor change-outs is racking up more than I thought it would be.   Thought -- with 19 Raptors out there if there was a big issue with folks having float bowl overflows as a repeated issue I think we would have heard about it out of 19 people that are reporting.

OF, I did not have a petcock failure on my bike!  I reported correctly.  The one that I offered to Routy was one that was on the bike that I got from Lancer that I am now parting out.  I do not have a Raptor at all, on either of my Savages, nor my S40.

Sorry,  Babyhog, I made those ASSumptions that caused my error based on interpreting what you said running it against what changes the poll information showed -- ASSumptions are not smart to do and I do apologize for my poll ASSumption error.

So it is 37.14% with 70 bikes reported  (and I am not going to assume that Babyhog punched in the rest of her bikes as assuming makes me an ass more often than not and I need to REMEMBER that ,,,,,,)

Its ok sweetheart, it was a logical ASSumption...   Wink

I did only vote on MY 2006 S40.  I don't think I can vote again, and I don't know the history of my son's bike, so I wouldn't vote it anyway.  The petcock from that parts bike, we pulled because the tank had a hole in it, so it wasn't gonna be used on that tank!  If I remember correctly, we did use that stock one on my son's bike because the seal on his was bad.  But both those bikes had been sitting for some time.

..... and it is amusing to me that the ones who still think the stock petcock is a good idea are busy collecting up a spare discarded stock petcock or two for when theirs fails on them ......


Are you gonna put a rebuild kit in it and then store it in a plastic baggie with a little oil in with it to preserve the rubber during storage?


And how old are those diaphragms in that rebuild kit anyway?


hee hee

My question is

What role does the corn juice in the gas play in the demise of these rubber parts.

The Accelerator Pump diaphragm went away on the Kawa W 650. The rubber compounds used in these diaphragms were decided on long before any ethanol was put in the gas. Maybe they should be Re-spec-ed with ethanol in the fuel taken into consideration..

But, hey, Im stupid, If you dont think so, ask Mick,

I think the corn juice (ethyl alcohol 10%) plays some role in the diaphragms giving up early and in the needle valve tips sticking in the brass seats -- exactly what that role might be chemically,  I dunno.  

Just a thought though since the big upsurge in "crapped out" petcocks and "stuck in place" needle valves seems to coincide with the roll out of 10% Ethanol gasoline nationwide.


============================


If the Savage stays extant through the next few years (in the E85 roll out years) I would expect to see some better alky proof parts come out of Suzuki that might jest fit into the older bikes as well as "upgrade pieces".

Not sure how my vote scewed (screwed) your data:

I had no problems....yet I replaced the petcock with a Raptor and my bike is less than 10 years old.

I replaced the stock petcock to prevent problems that may have been forthcoming.  I bought a 5 year old bike with 262 miles on it.....it did a lot of sitting around.  I just felt safer with a manual petcock.

OF. There is another reason to replace the stock petcock not mentioned in your poll. I did it so I could get the tank off easily when doing preventive maintenance. Also, based on all the discussion on the forum about the petcock, I became wary of the vacuum type and decided replacing it with the Raptor to be just another preventive maintenance task.

For what it is worth.
