Urban Express Petcock

Smitty Werbenjegermanjensen /

So my 82 Urban Express has had some "Repairs" in the past that I'm having to repair for real, and one of the surprises I've found is that the Petcock was molested.

The stock petcock is made by Keihin, and in all there forward thinking they decided to rivet the face onto the body, making a gasket replacement impossible without minor destruction. And one of the previous owners did do the minor destruction, then forgot to replace the gaskets.

As a result of that minor destruction, they attempted to ghetto it back together. They drilled out and tapped the rivet holes, but incredibly poorly so 1 of the 2 holes only has about 2 full threads and the screw they put in fell out while I was working on it. However it doesn't really matter because the screw's head was rusty, which I thought was weird until I realized why, it started out in life as a bulb headed screw but they grinded it down to a flat head leaving a minuscule amount of driver purchase which explained why unscrewing it was such a pain in the ass.

Squabbles aside, I'm probably going to need a replacement.

But I'm also: A) Racist against Chinese aftermarket parts, and B) A discerning gentleman.

And one thing Keihin DID appear to do correctly was implement a filter into the petcock, in an easily unscrew-able cup. And that's a bit of engineering I appreciate and desire. So I'm searching for a well made petcock with that same implement.

Or a well made petcock and then I'll begrudgingly do the fucking inline filter thing.

If you don't want Chinese (and I've blown through a bunch of crappy ones), maybe go with the one that treats sells

https://www.treatland.tv/OMG-honda-motorcycle-petcock-16mm-x-1-5mm-p/omg-16mm-01z3264267.htm

be careful with that screw area putting the petcock on. they're not always in the best shape. I cracked one on a tank and ended up having to have it rewelded.

If you do go Chinese, get one going in the right flow direction. A 16 x 1.5 mm. and use screws not rivets (but I think you know this)

this one may do it (the one I had work well isn't sold now)

Good luck

I went for the one from treats, cause there is one guy selling one unused OEM petcock for over a hundred bucks. Inline fuel filter it is *sigh*

An paper inline fuel filter is always a good idea .

Why do you think every brand new 4 wheeled vehicle has an inline filter installed before it leaves the factory ?

Cause they're 10 bucks for a 4 pack from amazon while a petcock with the filter built in is around $100 bucks from someone chuckle on Ebay
