And quite likely an MoT failure next time (if you are not "historic" have still one done).
My friend Andy has just had his Focus ST fail it's MoT - one of the failure points was that it had Led pilot lamps fitted (the other was a broken front spring). New spring & refit the incandescent lamps to get it though.
Seems daft TBH, as Leds on an older bike should improve safety, but I guess the clamp-down is as a result of the inconsiderate puuting stupidly bright, unsuitable Leds into headlamps on cars.
Have you changed the gearbox oil to something more suitable than EP90 yet ?
