Ah cheers guys, yep your right, ive just been and tested the coil. Bugger, looks like ive wasted my money on that rev counter then, Any one want to buy it for there air cooled one that has a dizzy?
I do have this hour meter/rev counter that ive just tired and that works.
I bought it for a 2 stroke bike i had that never had one and i wanted to know the revs it was using. You can change the settings for how many cylinders.
As the coil fires twice and (ones a wasted spark) i set it to a single cylinder engine and it seams to work.
Says its ticking over at 750rpm
