Manufacturers Description

The Boyer Bransden range of Analogue MKIII ignition units are being progressively changed to improved MKIV versions. The changes are designed to improve the timing stability if engine starting with a very low or variable battery voltage. The design changes are internal and do not affect the external appearance of the unit. Identified by the 'MKIV' caption on the label the new units are fully interchangeable with previously produced MK3 and MK1a units, and offer improved performance for both electric and kick start machines. All Digital and Power designs will remain as before.

    Fitted Boyer Mk1V to my BSA B25 which was suffering from a number of running problems. It was not so difficult to fit as I believed, in fact it was quite easy. Bike started first kick and now starts and ticks over beautifully. My only criticism of this unit is the quality of the crimp-on terminals. Other than that it's brilliant.

    This is the second unit I have fitted. I fitted the first unit to my A75 BSA which improved performance and eased starting. It is so easy to fit to any bike that any one with very little or no mechanical knowledge could fit it. This unit has done the same for my B50 BSA. The appearance of the unit when fitted is not unsightly if fitted where it can be seen but, if like me you like to keep the appearance of the bike as near to standard as possible it is small enough to put out of sight.
