Some carb adjustments & now idling nicely. Itching to get the side stand finished so I can go for the first test ride.

Test fit of modified side stand — looking good. Should have the bike on the road soon.

Thanks. But, rats.

Petcock leaks around a drip every 10 ~ 15 seconds. It’s a reconditioned petcock that I bought from somebody a few years ago.
Plus float bowl gaskets weep a bit — perhaps because of the leaking petcock.

Wanted to have it ready for a local show next weekend. So I’m looking into doing a manual conversion of an old petcock.

Difficult to use an inline tap unless you use a later single pipe version and a 3 way 'T' piece to feed the 3 carbs.

I’m converting an old GT-series 3-outlet petcock to manual.
Pretty straight forward: block off the two passages to the vacuum value with set screws + JBWeld, and flip the lever mechanism around. This gives you off (lever down), on (lever forward) & reserve (lever up).

If you can, post pics of the 'mods' to the tap and I'll 'sticky' the thread for others to easily find.

Petcock mod worked great. Will post a separate topic detailing the mods.

First ride — started & ran perfectly. But mother nature noticed a spiffy new cafe build on its first ride & the results are:

Oh, soggy heck (or similar). But on the upside, that gold looks well when wet.
