CT90 Engine Exposed!

I was finally able to get around to doing a project that I have been wanting to do for some time and that was to take a bunch of extra CT90 engine components and build an engine using cases that I had machined to end up with an engine that would enable you to see all of the internal components.

Here is a picture of how the final engine turned out.

Once I had the engine built up I decided to make a video and share it on YouTube.  In the video I show the engine running and also provide detail views showing the changing gears, operating the clutch, and how the piston and valves interact.  I also included some slow motion video that really provides insight on how the internals of a CT90 engine work.

Below is a link to the video on YouTube:

I hope you find the video interesting and informative as I enjoyed really enjoyed pulling together this project.
