Maximum engine performance depends on the fuel flow out of your 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.
