Pretty simple, and install instruction might be included with the purchase..
Other than that, run the bike till its low on fuel, or disconnect the fuel line from the existing petcock, and drain the tank into a 5 gallon can, yank the tank, turn it on its side and set on a towel covered old tire... remove the petcock, follow the Murph instructions...
Not sure which you are doing, the Pingle swap, or the Bergmen parts re work, but both have instructions.

Now, I will correct myself, he states no instructions.. sorry... but upon disassembly, if you lay the parts out, it may be clear how the new ones replace the diaphragm... can't say as I don't have the kit in hand. Sorry..

The bad; {After you install a manual set up} If you ever forget to turn off the Petcock when your done, you have an increased probability of Hydrolock...

PS: Your existing petcock is already manual...
      Turn the valve to prime, and the fuel flows until you turn it back to a {properly operating} "run or reserve" position.

Ride safe, Ted

Well, that's not correct... its only manual in the respect of choosing Prime/on all the time, or Run/Reserve "Vacuume actuated"... c'mon Ted, you know there is no positive "OFF" position.... :-[ :-[ :-[
total / partial failure of the diaphragm/spring/poppet can still result in one that leaks past the seat, and in combo with a questionable float needle or two, may result in the hydro..

Geez, we have a Sea Lawyer.   :truce:

I wuz referring to; he could turn it "manually" to "ON" now.....
  {I sed this because many new folks don't realize that the "Prime Position" bypasses the diaphragm/valve}

While I'm splainin';   It is "manual" bekuz; Ya turn it "manually" with your fingers (or in your case, ya turn it "manually" with your "other".)......    :-\

PS: Even on a Manual or converted petcock, you can never absolutely know the fuel flow is stopped.
      A leak can still result in one if fuel leaks past the valve.
        That, in combo with a questionable float needle or two, may result in the hydro..
      ie: S__t happens...  :nananana:

The best petcock on the market is the Pingel. I used Pingel valves on my Dragbikes for 20 years and had one on my C-10 for 8 years and it still serves the new owner today.

I purchased Murph's manual kit, and love it. Course I been motorcyclin' for a few years so I started out with the manual fuel valve and had the habit that I had to 're-learn' For the first few months I had a small label on my tach face "FUEL VLV STUPID!!!"  or something like that :) If I remember Murph also included a label with FUEL on it, or something like that.

Install is pretty straight forward, you will need to remove the valve from the tank. Carefully disassemble in a clean area with out interruption, the diaphragm cover gets replaced with Murphs part, and there is a set screw you CAREFULLY turn in to close the diaphragm, then lock it with the nut. Replace the stock lever with the Murph one, you are re assembling the valve with these new parts and, it's dun. Of course Murph does have the disclaimer in the description "THIS KIT IS DESIGNED FOR INSTALLATION BY EXPERIENCED MOTORCYCLE MECHANICS WITH NO LESS THAN TWENTY YEARS EXPERIENCE AND HOLD AT LEAST A B.S. IN “ALL THINGS MECHANICAL”.  ;)

Like I said, I like it.  I also have had the the Sefsick carb spa/overflow tubes installed so for those moments I do forget to turn off, there is a little backup should there be the carb bowl system malfunction.  My biggest forgetful piece is actually forgetting the start up procedure and turn the fuel back on,,,,,,yeah, happens, on a warm engine, you get abooooooout 2/10ths of a mile......... :))
