A brighter spark
It doesn’t matter what make your bike is, without spark it’s an ornament. One of the problems facing owners of more modern twinshock and evo machinery now coming in to the classic scene is the ignitions contain components which are not owner serviceable in the way older ignitions were. Once you add in that often such ignition parts are probably obsolete now, then it starts to get interesting.
Luckily for owners of ‘B’ and ‘C’ models of Yamaha’s DT360/400, Rex’s Speedshop can help solve your ignition woes with their Pulserless Cdi/pick-up repair kit. These models have a black plastic pick-up that is no longer obtainable additionally, neither the pick-up or the CDI were a good design to start with, both are known to cause problems and it’s difficult to tell what is causing the problem.
Rex’s pulser-less CDI unit does away with this troublesome pick-up. No other changes to the charging or electrical system are needed, even the HT coils stays the same! Downside? The back plate of the generator needs the adjustment slots elongating which means setting the timing with a strobe lamp, but otherwise this is an extremely neat solution.
WHAT IS IT? It is a pulser-less CDI unit for DT360/400 Yamaha two-strokes. WHAT’S IT COST? The export kit is £99.95 but if you want them to do the machining there’ll be a £40 plus VAT charge as well. WHERE DO YOU GET IT? From Marcus Rex at Rex’s Speedshop rexs-speedshop.com Tel: 01580 880 768
