| A close view of the exhaust opening. Imagine how close the exhaust is to the O-ring. |
 |
| Intake port opening. Just grinding small amounts can change the port timing quite a bit. The rotary is like a two stroke where port location is like cam duration and centerline on a four stroke. |
 |
| You can see how the bridge supports the side seal even with a huge intake port. |
 |
| With side ports there is no overlap as you can see here. This makes for a much cleaner engine. |
 |
| After the side exhaust ports close, you can see how the rotor exhaust port really increases duration by keeping the exhaust going longer in the cycle. |
 |
| The difference is more obvious here. |
