In some cases it may be necessary to limit the maximum pre-ignition. These small stops are used on the centrifugal governor instead of the red bushings. This will reduce the maximum pre-ignition by about 5-6 °.
-necessary for high compression with original ignition system
-suitable for all 2V with contactless ignition system
-is placed in the impulse siphon box on the original centrifugal governor
-replaces the original red bushings
-static ignition timing remains the same
Note: We recommend the use of this ignition timing limitation when using a 1070cc kit without adjusting the combustion chambers
