Here at Moore Speed Racing, we have a large ultrasonic cleaner big enough to fit a 4 bank set of carbs. Gummed up carbs can create very bad running issues and makes bikes un-rideable. With fuel being mixed with lots of additives nowadays, it can turn stale very fast leading to blocked jets, needles and creating a film of gum throughout the whole of the carbs.
Ultrasonic cleaning is the best way of cleaning carbs and all the fittings as it heats the solvent up then agitates the dirt in places impossible to clean any other way.
Prices starting from only £35 for a carb strip, inspection, ultrasonic clean and rebuild.
