Pretty darn cool!
Personally, I think off-the-shelf engines are easiest and simplest. Someone else has already done engineering and hard work ahead of time. Someone's put a Honda CR250 engine in Ninjette. Also RZ350 engine too I think. With turbo! Only saw this being built-up, don't know if it was ever completed. Also there's 4-part series on YouTube about turbo EX500. Guy supposedly had done numerous ZX10Rs and Hayabusas previously. So EX should be simple. |

Oh yeah, he's on the Kaw triples board. We've been talking about it a little. It seems to be a really good design and apparently runs well so far.

Slipper piston design is cool. Wonder how much rocking there is and how long rings last.
Want to see his MSQ maps. Maybe I'll sign up on Kawi2strokes. |

Wow. There's unique design elements in that motor that I'm having a hard time understanding but the whole thing is very intriguing.

There is a lot going on and the don't show all of their CAD designs because of the patent, obviously they want to sell it to you and not have you replicate it. It's leaves a lot of questions unanswered to those not in the know, and those who do know are more curious about the fine details of operation, stresses, porting, timing, cooling, etc. |

Once the patent is issued, get yourself a copy and build your own 2-stroke 500! |

Oh you are totally right, I completely forgot about that. The end of the video says patent pending so I misspoke.
