If you hit the rev limiter far too often, this modification is for you. We electronically re-programme the rev limiter on your twin's igniter to trigger at 8,500rpm. This has been proven to work well for engines with improved breathing on the induction and exhaust.

All carburettor models are covered, Bonneville, T100, and Thruxton. Just send us your igniter unit and we make the changes and minimize your down time by having your igniter back in the post within 48 business hours of receiving it. This is a worldwide service and your igniter is insured for the return journey.
