2002 Works Honda CR250 Build RAW - Motocross Action Magazine

#dirtbike #twostroke #motocross #motorcycle #outdoors Motocross Action goes on the quest to build a works Honda CR250 Two Stroke build. You’ve seen the full test video. Now we come back with a completely raw form for our viewers to enjoy. As for the engine, VForce intake mods were added to enhance throttle response and overall performance. For the carb, Chad went up from the stock 380 main jet to a 420 main jet, a 40 pilot jet and a needle jet that is no longer available. The bike had enough mid-to-top end power for me in stock trim, so the cylinder was just cleaned up with mild porting, the head was polished, and a new piston and rings were installed. After talking with Chad about what pipe to run, he said the Pro Circuit Works pipe and 304 silencer were the best fit to help the bottom end out. From there, I built my own 5mm-longer aluminum exhaust spigot to increase low-end torque. I also ran a Loudmouth air intake system and PC carb vent canister that was routed and mounted per Chad’s specs. MARK CHILS
