Well, here's my 2 cents.
Of course, I will accept change back.
4 strokes (Motocross wise) have dominated the scene.
So, with that in mind, it can be done and has been done for some time.
Also, Just because the video looked like it was hard to disassemble 4 stroke
doesn't mean by this evening, a true R/Cer would not know how to have that
thing taken apart and put back together blind folded. I know, If it were mine
I would by tonight..

Also, RPM is a problem now, but, after some time, someone would work to
resolve this by gearing or a better built engine.
And as for Rotary engines, I'm all for that as well. They like RPM. (Althought
I don't think they have much on the bottom for power)
20 minutes of run time is definitely something I would be interested in.
I would also wonder if it would last longer between rebuilds.
Give me the plans, I'll mill it up..



RotaryNut Maico 490 or 500. What a real mans bike.
Image that engine updated in a new frame bike.
Wooo Mama...
