Pump Gas VS Race Gas

When To Use Pump Gas VS. Race Gas

The term “high performance” gets thrown around a lot when talking about engines and the vehicles they power, but real high performance requires high performance fuels.

Both natural and synthetic rubbers have their pros and cons, but that is a very in depth topic that I won't get into here. This article will focus on the benefits of using a natural rubber inner tube for dirt bikes. Natural rubber is made from the sap of the rubber tree.

Introduction To The 2-Stroke Power Valve

An Introduction To The Two Stroke Power Valve – What It Is & How...

Back in the day, two stroke engines were very limited on what their power bands could do. One power band might be able to produce a rush of power in the low-to-mid rev ranges. Another power band may have produced a power rush in the mid-to-upper-high rev ranges. Still another might produce a lot of power only at the top-most range. There were no in-between, and there were no...
