Other types of Petcock

[cboling]

A while back I was looking around at the racing sections and the wiki for race bikes and saw where a Pingel petcock and adapter plate can be made to fit the GS500. I was wondering if there are other solutions that would be as good? I have contemplated getting a standard bung and welding it and closing off the original holes. I thought I also had seen an electric petcock that I assume shuts off when electricity is removed from the solenoid?

Anyone have any insight or want to start a discussion on this?

I have already removed the diaphragm in mine and sealed up the small plastic piece so that it is full gravity feed but I am thinking more along the lines of removing all the unnecessary lines and simplifying it. Maybe making it a little bit fail safe against leaks.

Considered the same thing for a while. 

Went with a Veypor gauge, so I don't need the reserve function, either. 
Didn't weld a bung.  I just blocked off the higher outlet, and ran a single line from the reserve. 
That retains fuel shut-off at the tank.

I use surgical forceps to clamp off the hose, if I need to change jetting.  But, you could install one of these:

The o-rings fail fairly frequently, and won't stand race gas.  Change them every time you disconnect, or use vaseline. 
100-pack of o-rings is about $9, from here:

BMW guys say the plastic ones fail often, so you could use this, instead:

Or, use this and bypass both problems (no o-rings, better engineered fitting):

When I find the cash, that's what I'm switching to.

If you want a smaller manual shut-off (that you'll forget to actually use), this place has the smallest metal one I've found:

I DO still use an inline filter.  Haven't been able to find a small one that doesn't deform from ethanol, so I stick with a rebuildable one with glass sides.  I like the visibility.  Considered tucking it into my lunchbox..... but, no. 


These aren't bad, for the crankcase vent:

Pricey, though. 
Haven't really looked for anything else.  I just let mine drain. 






Another option, if you want to retain reserve function:
-Install a shut-off in the reserve line
-Tie both lines together, using a "T" fitting, AFTER the shut-off
-Run the single line to your filter or carb T
Same basic idea, really.
