I know some of the old heads out there will know this, so I'm inquiring about petcock screw spacing on the old ' 78-'79 GS1000E's. Need to know
because I'm looking for an aftermarket petcock and need the distance between screws. This is the old style petcock before the one without the lever.
Thanks in Advance!

Thanks, somehow, someway, I will overcome this leaky petcock issue of mine, in the meantime I'll continue to use the one with the wrong filter that otherwise works perfectly.
 
Sorry to necro-bump this thread, but does anyone know the bolt spacing for the 1978 GS750?

Cross checking the parts from the 1978 GS1000 answer here shows a different petcock part no. The O-ring, however, is the same. So I believe the spacing is also 44mm, but I forgot to measure that last night.

TIA

While you're bumping, I'll pile on.... I got one that is 46 mm spacing- alleged from late 70's suzuki- maybe someone will recall it-see pic
 
My 78 gs750 tank is 44mm, the 44mm adapter plate from Z1 fits perfectly.
 
Hi, I'm new here, I'm from England and have a 1980 gsx750 et and I've been having trouble sourcing the correct petcock for my tank, it is the type without a lever and the inlet and vacuum pipe facing the front of the bike, the spacing is 51mm, I don't know if that helps.

Try this Florida guy- BUT he claims mounting holes are 50 mm; he might measure wrong-so ask him nicely to measure again.
I bought a different petcock off him - exact copy of my original.

Welcome, if you are lucky, A guy named Basscliff will greet you with info!
