Suck Squeeze Bang Blow

Suck Squeeze Bang Blow is an easy way to describe the four cycles of a combustion engine. The engine sucks in a fuel & air mixture, then squeezes and compresses until it explodes with a bang, and then finally blows out the exhaust.

We were working on this little vintage Honda CB350 twin engine and I couldn’t help but see two faces in the exhaust ports. These Siamese twins seem to have been debating for decades now.
