Hi after help, relatively new to trials not a lot of knowledge, had the bike a few years and always run well for its age, was riding a few weeks ago and it just stopped, no spark, done the usual tests plug, kill switch bad earth ect but with no results, I've been in contact with a few stator rewinders and they say that the 12 coil stator that is in my model are pretty much bullet proof so would more likely to be the pick up, the CDI box or the voltage regulator, the pickup has been tested by west country Windings and it's ok, so down to it most probably being the CDI box, these apparently are extremely hard to find now, I have also been told that Kokusan do a complete ignition system for this bike but I can't find it anywhere, does anyone have any fixes for this problem , cheers Rich
