Developed by Kibblewhite, these decompression valves are a robust and precise solution to facilitate starting phases and limit starter strain. Designed for road and vintage use, they also fit demanding trails and roadsters.
The custom-moulded spikes provide a secure grip and controlled contact temperature for comfortable handling on a daily basis. These valves are designed to engage during starting — particularly to reduce difficulties associated with hot starts — while limiting the load on the starter and battery when properly installed.
