Thanks everybody, but what I still don't understand is how the timing can be off by anything more than a degree or two on an engine like the DL where the threaded holes for the the hall sensor mounting screws are already drilled and tapped into the front crank case. The holes are slotted (a little) in the sensor, but that leaves little room of adjustment (mis adjustment). Only a degree or two. So, how far off can one really get the timing on the DL?

Thanks again.
