Need a K8 750 petcock... anyone bought one lately?..where to find....

The mounting nut is 22mm and the tank thread is 15mm, I think  :) Aftermarket type would be good... stock one is N.L.A.  :(

The one that is pointed out on Ebay would work, as the seller says, but the outlet spigot is aimed toward the rear of the bike so the hose would have to be longer and make a loop toward the carbs. The proper spigot for the 78K 750 has the outlet headed out the back of the valve, more or less aimed at the carbs. Like this one:

Thanks guys, ideally one with the spigot out the back would be best...... I'll try on 'Parts Wanted ' too , maybe someone has one off a bike  :)
