BSA & Triumph Trials PVL system (complete kit with machined rotor and ready to fit 3/4" crank) In our opinion the PVL Electronic ignition system is the best modification you could do to most 4 stroke TRIALS BSA & Triumph single models . This top quality German product is an Analogue system which gives a strong reliable spark for easy starting. It comes complete with everything you need for installation including instructions. It fits easily where the original Lucas system would mount and eliminates the need for a battery,distributor or points as it is self generating. Please note, Ignition Only, does not run Lights, switches or any other electrics. Please note this system is not suitable for the Tiger Cub (we can also supply Cub systems but to fit some crankcase machining is necessary) We can also supply twin cylinder versions of this system for trials and also single and twin systems for motocross.
