when the tach is showing RPM's, is that the actuail number of times that the crank turns 360 degrees, or is it it the number of times/minute that the #1 cylinder is fireing?
sorry for the newbie question, but my brain isn't working at the moment. :wall:

Crank revolutions per minute

so in that case, if the tach is reading, lets say, 5000RPM, the #1 cylinder is fireing 2500 times per minute?

Wouldn't it be 1250 times per minute?

5000 rpms's
4 strokes
=
1250 times per minute

Edit: Nevermind. 2 strokes = 1 revolution. Carry on.
