Can you post the sizes for the other taps you have for the frame and exhaust threads.

Hi Joe,
When I put the POR-15 in my tank to seal it, I let the excess run out the petcock holes. Needless to say, all of my threads were clogged. I thought about trying to get ahold of the right sized tap, but they are hard to find. Instead, I used a 6mm x 1mm tap and just turned it around the circumfrance of the hole until the threads were cleaned out. Took a bit of time, but I didn't have to wait a week for an expensive tap to arrive. I grabbed ahold of the tap with the vice grip to give me something to hold onto.
As for the size, they are 12mm x 1mm.
I do have a couple of hard to find taps that I would be willing to lend to anyone in need (just remember to send them back!):
1. swing arm thread tap...for the theads in the frame. 2. exhaust thread chaser...for the the threads in the exhaust port of the head. This one will clean up the threads, but is not intended for cutting new ones.
If you need something, just let me know.

Would anyone know what the thread diameter & pitch is for the spigot that the petcock threads into? I think I read here a while back that it is 10mm x 1mm - sound right? I have to do a repair to the paint on my tank - it bubbled up around ther filler neck. While I was at it, I wanted to purchase a tap & chase out the threads in my tank - one side was buggered up & damaged a petcock, and dollars to a donut, it's going to bite me in the ass when I start to mess with it. Any help appreciated!

The ones I made for my Eldo have been leak/weep-free for over 3 years. They are made from a sheet Viton. I use hole punches (got metric ones now) and an old gasket as a template. They go for $.50 each since the Viton is pretty expensive stuff. I've found two versions of Ambo/Eldo petcocks, Orlandi ('sugar cube' style) and 'other'. Tell me which one you have, and I can make them up.
And yes, I'm making millions!!!

Be advised....
There are two versoins of the Guzzi petcock.. The V700 are different than Ambo/Eldo ones.. as I understand.
I got some rubber ones from a lister. Haven't put them in yet....

Hi Alan:
I've got a shop making me a bunch of teflon ones. They won't break down like the rubber ones and are self lubricating. You won't have to strong
arm the petcock open.
I should have them in a week. The price will be $4.00 including postage.
