Great video. I eventually found the same problem after fighting drivabilty, hard starting, and getting stranded twice. The plug would come out super fouled. I rebuilt the carb, even bought another one. When I saw the fuel leaking from the actual petcock I replaced it with the raptor petcock and all these problems went away. It is reliable in starting and riding now over the last 3 years.

Everybody please listen to this Guitar Guy. I'm on my 2nd Savage/S40. My first one was a 2003 with only about 1700 miles that I got in 2007. I remember having what I thought were all sorts of disappointing carburetor problems on a bike with such low miles. I had wide open stalls, bad behavior in the rain, flooding, etc. I tried everything. I even had a guy from the aforementioned forum suggest stiffening the spring on top of the diaphragm (dumb idea). I stumbled on the thread about converting the petcock into a manual one, and I successfully did it. I'm not sure it's the same fix SGG highlights here, but I think it may have been. I'm a stubborn guy, and I resisted the Raptor conversion for some reason. Maybe I wanted to keep everything "stock". The Suzuki petcock was hateful for another reason. The lever was stubby and extremely hard to turn. I remember taking the stock petcock off to do the conversion and finding that the 4 screws on the back weren't even very tight at all. That may have been most of my problem. I think I only kept that bike for 3 years or so, because a beautiful 2003 Sportster caught my eye. All the bugs were worked out when I sold it. Fast forward to 2022: I decided to pick up a 2012 S40 with only ~900 miles on it. It was somewhat of a mess from mostly sitting, and one of the first things I did was swap out the factory petcock for the Raptor one. It was the right decision, because my first oil change included a gushing torrent of gassy thin oil that overflowed the drain pan. This is a symptom of a misbehaving petcock. The bike is now in good working order, and I turn off the petcock every time I stop the engine. *Some* of these bikes are prone to flooding with stock carburetors, especially in hot climates where I live. I think I have a glitchy float valve (over $76, strangely, from OEM suppliers) but a manual petcock eliminates any variables created by a hot pressurized gas tank. I cringe thinking of somebody leaving the bike on PRI all the time, because that wouldn't have worked for me on either bike, I'm afraid. Thanks Some Guitar Guy for the interesting and thorough video. I'm with you on the pure gas too. It's readily available where I live due to the boater culture, but I find myself forgetting to put it in my bikes every time.

Just replace it with the Raptor part, like he said. This is the one thing that is an absolute necessity on this bike, you won't regret it!

I have been having the hard starting and not running problem for some time, today the engine would not run unless petcock is on PR1. After seeing your video I have ordered a raptor petcock for Yamaha 660 and I will let you know if it cures my problem, thanks for the video.

Thanks man I had all these problems and just cleaned all the jets in the carb only to find it did nothing to solve the problem. The gas would dump down that vacuum line causing my bike to flood out and when it shut down a massive backfire.. I ordered the petcock from the raptor, only cost me 20 bucks. I hope this does the trick.

Just bought a savage. First bike. Noticed the hard start. Had to choke it and set to prime. I would try and ride with it on the on position and it would putter out after a minute or two. It seems to ride fine in prime position. I also notice a gas smell when it’s been sitting. I got a raptor petcock I have need to put it on already.

Good video sounds like this may be my problem. I don't know if I missed it in the video or what, so what do you do with the vacuum line on the motor

We’re on the Carburetor do you plug the hose to from the Petcock also what do you do with the vacuum port?

Thank you

I recently removed my carb for a cleaning. Unfortunately my fuel outlet (brass tube) came out with the hose due to corrosion. Does that need to be pressed back in? I did my best to tap it in without flaring anything. I’m definitely leaking fuel from it now. Not sure if I just need to get it further in or did I fry the piece completely.

I havea question. What do you do with the vacumm line?

So I just bought a 2009 s40 and I can only ride with it in the reserve position. Will not work in the on position. I also get backfire. Could this be a system of a bad fuel cock? Should I replace with the raptor? And can you reply with the link for the part that will fit my Suzuki s40? Thanks for any help!

Would this explain mine frequent backfire? 2013 s40

My fuel cock for my s40 seems to starve for fuel if the fuel is on and seems to run fine on prime. No leaking yet on either. Is it ok to ride it on “pri”?

Do you have to take the tank off for the install? Or can you just take it off like that

runs fine until i off throttle , after fire... ive adjusted the brass engine side to 1.5 wish me luck

There is more vacuum at idle than higher rpms
