I bought my wife a CRF150RB. The jetting was way off. I cleaned the carb and installed the JD Kit. After getting it installed and warming up the bike it ran like a champ. Throttle response was smooth and started first kick every time. Takes the guess work out of jetting.Read All Reviews

Got carb cleaner on rubber gasket and float valve, swelled both now can't use, called shindy and they didn't speak English and couldnt help me. I called rocky mountain and they said there was nothing they could do. Neither company would stand behind their product so they lost me as a customer. TECH NOTE: Keep carb cleaner away from rubber components. The carb cleaner will ruin them.Read All Reviews
