Jets
Need to tune your carburettor for a new exhaust, a freer-flowing air filter or a different altitude? Under Jets you’ll find jets and related carburettor parts so you can fine-tune the air and fuel mixture. They are small parts, but they make a big difference to how the engine pulls, idles and responds to the throttle.
Small parts with a big effect on the engine
A carburettor meters fuel through a series of calibrated jets. The main jet mainly controls the mixture at wide throttle openings, while the pilot jet matters at low throttle and idle. When you modify the engine, for example with a new exhaust, a different air filter or more power, the airflow changes too. The jets often need to follow suit if the engine is to run cleanly and smoothly. Many riders also change jets when riding in different climates or at higher altitude.
Jets’ key products
The range mainly covers main jets and pilot jets in different sizes, as well as kits with several sizes so you can experiment without ordering again and again. Depending on the product, you’ll also find parts such as needles, needle jets and carburettor gaskets. Jets are available for different carburettor types, so it is important to choose the right thread type and size. See each product for carburettor fitment.

Frequently asked questions
How do I know whether I need a bigger or smaller jet?
If the engine runs heavy, smokes and starts poorly, the mixture is often too rich and a smaller jet can help. If the engine runs hot, stutters or lacks pull at wide throttle, it may be too lean and a bigger jet may be the answer. Always change in small steps.
Can I use a jet kit instead of single jets?
Yes, a kit with several sizes is practical when you are tuning the carburettor from scratch. You can try several sizes one after another and pick the one that gives the best result.
How do I know if a part fits my car?
Contact us with your car’s make, model, year and preferably engine code, and we’ll help you find the right part.
