hi all
i purchased the tach in the above thread. to my amazement it is inductive....4 wraps around the spark plug wire. well static test just changing rpm's and comparing the analog tach with this digital one, they read just about the same. the digital tach isn't as fast as the analog one. so i can assume that the tach is not off by 500 rpm... i checked the sprocket and its a 15 tooth sprocket. i didn't check the rear socket.... so now the 500 rpm difference between me and the rest of the world is still a mystery. any idea"s ??? anybody..
