180 deg....360 deg....hmmmmmmm Are you thinking that one full cycle of one piston is 720 degrees?? Yea, that would be 360. I was thinking like an electronic tech and one cycle is 360 deg and I just split it in half

gawg,...I must be getting old.....getting harder to switch in between disciplines anymore. Elect Tech to Mechanic to Expediter......

Now, I'm getting confused...

A 360 crank is both up (or down) at the same time but one is compression and the other is exhaust.

A 180 crank is one up and one down with one on compression (or exhaust) and one on intake (or power).

That Yam 650 I just finished was a 360 degree floor shaking vertical twin...sure was smooth on power though.

Yep. Not hard to sort out a 2 stroke...up, down, up, down... Here's an S3 that I repaired a couple months ago.
