The  Power-Flo® petcock from Pingle - complete kit for Yamaha RoadStar (requires minor enlarging on the inlet hole with a round file).

If you are looking to get rid of you stock fuel pump this is your first must have!

Only using the Pingle Petcock, proper fuel line and the Pingle High Flo Fuel filter can you eliminate fuel starvation when pumpless even with our Maxair Racing 42 car. Cut corners and you'll starve for gas when you need it most.

 From Pingle:

Maximum engine performance depends on the fuel flow out of you fuel valve.  Research has proven that, at a flow rate of only 28 ounces per minute, stock petcocks can starve even stock engines.  If you modify your engine in any way, more fuel flow is required and must be supplied or you will suffer major tuning problems.  Just increasing the size of you jet will not make more fuel available to you carburetor at higher RPMs.  What is the solution?  That's easy...Pingel^® Fuel Delivery Systems.  The Power-Flo^™ single outlet model has a flow rate greater than any other stock or aftermarket fuel valve.
