Over time, fuel leaves varnish deposits, float valves stick, and jets clog up. Symptoms like bike won’t idle, bike won’t start, or carbs flooding are all classic signs that your carburettors need attention. For some riders, this means pulling the carbs off the bike and stripping them down — a messy and time-consuming job.

A DIY carb clean often involves removing float bowls, spraying carb cleaner, and brushing away visible deposits. But this doesn’t reach the internal passages where blockages cause poor fueling. That’s where ultrasonic carb cleaning becomes invaluable. By immersing your carbs in an ultrasonic tank, microscopic bubbles scrub the internal fuel circuits — something impossible to achieve by hand.

Another consideration is whether to rebuild carbs or buy new. Replacement carburettors can be expensive, often running into hundreds of pounds, whereas a carb rebuild service with new gaskets, float valves, and O-rings restores performance at a fraction of the cost.

If you’re weighing up the options, ask yourself:

• Do I want to learn how to strip carbs myself, with the risk of damaging small brass jets?
• Or do I want the peace of mind that comes from a professional carb cleaning service that guarantees results?
