Snorkeling & Jetting
I have a 2008 BF 650i, chipped, snorkels, hmf pipe, k&n air filter, clutch kit. It has a hard time starting when it's cold and farts through the carbs at idle and when riding. If it's idling.. its fart through the carb and kill the engine.
I looked at the needles and they're shimmed at the 4th...
