Hi all! New savage rider/ new rider in general. I got the raptor petcock to put on my 2001 savage with around 8000 miles. (Ordered of of newegg for 7 bucks) came in real fast but didnt have the o-ring gasket. I stuck the oem petcock oring on it and just used some liquid gasket to fill in the spaces that the o ring didnt. It sealed just fine with no leaks. And i also stuck a lawn mower fuel filter from tractor supply on it. I was just wondering about yalls opinion on this liquid gasket stuff. Good to use? Bad? Okay for some things?

watch closely for leaks..
1. the cheap chinese petcock may leak after a spell
2. not all gasket material is fuel-proof, silicone is not

good luck,
gary

When the Real McCoy costs just under 30 bucks, and can be had with no shipping, BTW,
You gotta know that a seven dollar answer is a fraud.
We have all been told
You get what you pay for
But thats a lie.. WE pay good money for bad products & services all the time,

However, what IS true is
You will pay for what you get.. & if you need a quality part,, youll pay a quality price, 7 bucks aint it,,BUt you sure arent the first to buy one,

& Yea,, unless you gut a Fat honkin filter, its likely to cause problems at higher throttle settings,,

You are headed for trouble.

The petcock is 100% brand new....but not from Yamaha.
Silicone gasket sealer is not fuel proof.....it will leak very soon.  You don't want to be dripping fuel on the hot engine.  Not long ago I was curious about this and put a small hole in the side of a soda can, applied silocone gasket material and let it cure.  I put gasoline in the can, and within a few hours the gasoline was leaking from between the can and the silicone.

Just write of the $ 7.00 petcock as a cheap lesson, go buy the proper Yamaha petcock.....and get on with your life.

Here is the data sheet for the Silicone product you used.  Notice the comment about not using it for contact with gasoline.


PRODUCT DESCRIPTION: Mega Black Silicone is a single component, moisture curing RTV (room temperature
vulcanicizing) silicone gasketing material that cures into a strong silicone rubber that maintains long term durability and
flexibility to make formed-in-place gaskets. Mega Black Silicone is a non-slumping, paste-like consistency which cures
when exposed to moisture in the air. Forms a tough, flexible silicone rubber gasket that resists aging, weathering; will not
harden, shrink or crack. Remains more flexible than conventional gaskets. Mega Black Silicone is non-corrosive to steel,
iron and aluminum.
WORKS BEST ON: Use to replace silicone, cork, felt and rubber gaskets. Use on valve covers, oil pans, intake
manifold end seals, water pumps, transmission pans, cam covers and thermostat housings.

I walked into the Yamaha dealership with my Zuki petcock, told them I needed a Raptor petcock, handed the guy mine,, walked out for under $30.00.. No hassles, no "Gee, I wonder if this will work,,", comes with an Oring, bolts right up, no fixing, no shimming, nothing,, poke it in & run the bolts down,,

Just out of curiosity, I checked with my local stealership the other day about one...$39.95 and they have to order it.

I have a cheap knock off with thge smaller outlket and it works fine.
