My tachometer has two settings: 5 and 6. It is my impression the tach should be set on 6. It's my understanding this is determined by the number of poles on the stator. How do you find out how many poles [the stator of a Suzuki DF70] has.

6 it is. Trust us.

To determine the number of poles in the stator winding you can visually inspect the stator and count them. Normally the stator is under the flywheel, so you will have to remove the flywheel to reveal the stator. I do not recommend you remove the flywheel just to count the poles in the stator, as it is a lot of work.
Alternatively, you could inspect a replacement part for the stator and count the poles on it. Perhaps your dealer has a replacement stator on his parts shelf, and you could inspect it.
You could also deduce the number of poles in the stator by measuring the frequency of the pulses coming from the stator while the engine is rotating at a known speed. You'd have to determine the engine speed using some other device.
However, I think Bob's reply has eliminated the need for all that.

Thanks, I had it set for 6, I just wanted to double check!
