The factory cylinder heads with variable combustion chamber are a must for every racer. The aluminum alloys and optimized combustion chamber shapes employed ensure the best possible heat dissipation. This has a positive effect on power delivery and reduces material wear in the combustion chamber and on the piston. Replacement of the whole head is now no longer necessary - simply put in a new combustion chamber insert and off you go again. To increase the performance of your bike even further, Husqvarna recommends combining factory cylinder heads with the following parts (sold separately):
- Factory / SXS spark plug.
- Factory / SXS CDI.
- Factory / SXS Pipe and silencer.
Note: The carburetor jets must be matched with the selected combustion chamber insert and the model year of your vehicle. Detailed information about carburetor jetting is available from your dealer.
