Fuel Petcock question...

[aosmith]

I took apart my fuel petcock tonight because i have no "off" setting so first off is that normal? secondly mine looked like this:

Fuel

Res PRI

ON

where PRI is bigger hole on reserve section of filter
FUEL is bigger hol on taller section of filter
RES is smaller hole on reserve section

Is that correct as well it can go together with the plastic valve one way but the whole assy can be installed in 2 directions:

NO

PRI RES

Fuel (upside now)

The second has a setting that would appear to be off

When the petcock is working properly, you leave it in the ON position. When the engine is OFF, there is no vacuum to open the petcock. When the engine is running, vacuum pulls on the diaphragm and opens the petcock to allow fuel flow. RES also depends on engine vacuum for proper operation. PRI is used to prime the float bowls if you think the fuel level has dropped for some reason. PRI does not need engine vacuum to allow fuel to flow, so it is recommended to not leave the petcock in this position when not riding. In fact, it should only be in this position for less than a minute any time you do use it.

Your petcock selector lever should be pointing down (toward ON) most of the time. When you run low on fuel, rotate it forward to the RES position and look for a gas station. Don't forget to move it back to ON or you will be in for a lot of exersize when you reach to move it to RES the next time. The amount of exersize is directly proportional to how far you are away from a gas station.

thanks for the response sounds like i'll be needing a new petcock (or diagram)

If it is leaking you can buy a new 0-ring for it.

Steve, is up hill both ways to the gas station, or down hill both ways?:-D
