Cb750 K2 Petcock blockage

<< < (2/2)

Jonesy:
Good deal! Another victory for our side!!!! :D

Bob Wessner:
After reading these posts re: the petcock, I'm now wondering if I assembled mine correctly last year. I get the overall idea of the flow and change between on and reserve, but now that I think back, I'm not sure I paid any particular attention to the orientation of the rubber gasket with the holes. The petcock works now, but now I'm a little concerned I may not really have a reserve. Can the rubber gasket with the holes be installed incorrectly so fuel flows, but maybe no reserve??

Jonesy:
If you used the rubber seal with 4 holes, you can't install it wrong. Of course, now I'm wondering... did the K0 use a slightly different petcock? I think the unused hole in the seal goes over a small projection in the petcock body to keep it from spinning when you move the selection lever. I don't think there is a way to put the lever on wrong, either... Of course, you can quickly ckeck buy pulling off a fuel line and moving the lever to the ON and RES positions. If you get fuel flow out of both, you're OK.

Bob Wessner:
Thanks Dan. I wasn't sure the flow test would be valid unless the fuel level was actually below the tube top in the tank, but I guess it makes sense that it would be.

Jonesy:
With the reserve inlet at the bottom of the tank, you can run through the whole tank on reserve... and then walk the bike to the nearest gas station. This happened to my buddy on his GoldWing after he forgot to move the lever back to ON after a fill-up. It concked out in a rough part of town, too!
