I remember the petcock on my 2003 Savage being incredibly stiff also. I'm sorry to hear you bought an expensive replacement stock petcock, because the design is inferior. I'm sure the new one will last you a good long time, but consider a Yamaha Raptor petcock that's mentioned extensively on this forum. It's manual, cheap, and ultra reliable. It fits with no modification. Sure, it's not vaccum, but it will never give you problems. In fact, I suggest you return the stock Suzuki petcock and purchase a Raptor petcock for far less money

Last week, I was fortunate to find a 2014 S40 with 1,700 miles. It sat for the last 8 years and needed some TLC. Upon first start, it ran smoothly for about 8 seconds but subsequently died. I drained the tank (varnished fuel) and cleaned the carburetor. I love the simplicity of this bike! However, upon reassembly, it still did not run. When I disconnected the fuel line, I saw it was bone dry. I’m unsure how the petcock let me drain the tank but then prevented any fuel from flowing, even on prime, but it did. (The petcock’s lever was also so stiff it required plyers to move.) Regardless, I ordered new petcock from my local Suzuki shop that should arrive tomorrow. With a little luck that should fix it and I can start enjoying the bike. Looking to forward to being part of your group.
I appreciate your advice about the Yamaha Raptor petcock. I’ve not yet purchased my OEM petcock. I see the Raptor petcock is about $50 less.
If I may ask a few quick questions about the Raptor petcock:
1. If it remains in the ON position when the engine is not running, will gravity still cause fuel to flow into the carburetor?
2. To put this into very simple terms, each time I turn off my bike, I must turn the petcock to the off position, right? Otherwise fuel will continue to flow, fill the carburetor, flow out of the carburetor into the cylinder and ultimately leak past the piston rings into the oil, right? Not a problem, I just want to fully understand. Of course, each time I start my bike, I must manually turn the petcock from the off position to the on position to allow fuel to flow out of the petcock into the carb, right?
3. With the OEM petcock, once the bike is running and the vacuum opens the OEM’s petcock’s internal valve, it permits the same “gravity” flow as the Raptor’s petcock, right? Any difference in flow rate?
4. The only benefit to the OEM petcock seems to be convenience. I can permanently leave the petcock set to the ON position and know that it “closes” when I turn off the engine.
5. Am I getting this straight? I think I like the idea of the Raptor’s petcock for its simplicity.
