Motocross Action is about the real world of motorcycle racing. Where stuff happens. Where parts break. Where bad products get foisted on unwitting buyers. Where good technical information is hard to find. We will show you the tricks that your local dealer won’t. You’ll learn how to keep from seizing the idler gear on your CRF450, how to master your Keihin’s fuel screw, how to minimize the dangers of bad gas, how to fix your suspension for under a dollar and whether you can run a 2005 CRF250 cylinder on your crack-prone 2004 model.
