If you need a petcock that is made without compromises, you'll want a Pingel. Pingel petcocks are world famous for their gas guzzling capabilities and if you think you don't need a high flow petcock... think again. With a regular petcock, when traveling at high speed, even with a stock engine, it can happen that your bike uses more fuel than a regular petcock can deliver. The engine sucks the float bowl dry, literally starving the engine. With High Performance Big Inch motors the problem increases. Pingel petcocks can supply the amount of fuel your engine needs to perform.
