As Johan says the boys in the box say impossible !!

stay outa the box

PS Johan
50CC is the limit in most USA regions where a license is not required [or license plates and insurance]
to drive on Public streets [do to power limitations of such small displacement] .
they call them MoPeds ..pedals and a small motor.
I think this will change that ...Yikes
Now I have to ask a question [so I stay on topic here]
How fast will it go [or HP calcs??] ??..and does it resonate ? ..it has the most unusual exhaust pipe ??
it resonates with me

Its all about freq en timing, this in there specific cavity, then to harmonise those waves of the different working parts to a ............. stabile resonance and combining the working parts to a Massive-Standing wave, this at 15-16K rev./min!

Make a circuit line, fill in the working parts, so:

Outside - Inlet-Disk,
Inlet-Disk - Transfer-Ports,
Transfer-Ports - Outlet-Port,
Outlet-Port - Mean-Point Exhaust,
Mean-Point Exhaust - Outside.

Adjust the Diameters and Volume's, keep in mind the related media Working Temp of that part, and much of TIME en TIME!

Thats the OU, of a 2-Stroke, to get more out 50cc than Thermo-Dynamic possible, this against the Book-Religion promoted Math by some One-Paper beginners here, Tinman is a queer-Thinker and OK!

Exchanging part from a circuit, like piston or a lamp is not always ................ , feeling the true working.

Marie Curie, did start out of feeling, not out of the books, that was just a almost blanc-base!

Its going over 200km/h, with the right gear-set.

Replace: Look for Electric parts, to make current / flux compressible, like ............ above!

it is probably much better for the Glass breaker and resident resonance king to stay in his Box !

he should definitely not comment on that which he has no idea about!!

ICE]s in particular ,

But the true possibilities of outside the Box thinking when it comes to resonance !

I use the word resonance because I don't have the Kings permission [he slaps all who use his word!!

resonance

he is a Deity and Legend in his own Mind
Just ask him ??
He knows everything you will ever need to know about RESONANCE [Just ask him ...he will tell you in a couple months
[his lordship is very busy]]

nothing to see here "move along"

7 HP per cubic inch ..
normally aspirated !!

They also have to have an automatic transmission to be legal in most states...no shifting allowed.  Wow, my scooter has like 3.3 hp and that one has 24?  Mine will do 49 mph, I'll bet that one would go over 100 if geared right.

PS  You can hear it when it hits resonance with that tuned pipe.  Here, we called it being "on the pipe" back in the 2 stroke Kart racing days.

Check out this 2 stroke scoot in the above link.  It has trouble keeping the front wheel on the ground when hitting the tuned pipe.  This scoot has 28 hp.

Thanks, Great that you know the: OnThePipe feeling!!

That is when the whole Fluide-Circuit is in Harmony, Resonate and massive Standing-Wave!

Your YT of 28pk, is only not a 50cc, its a Bigger-Bore 70-80cc, this on a Small 50cc Case, with a Reed-Valve, but very good tuned, TIME, to produce Max-Torque over Centrifugal and Variator, so always the perfect Gear in charge.

40 years ago, 12 or 14 gears to manage the Torque of only 3-500 rev/min:

4-stroke is more easy for school programmed tuners, on -off, little induction but still Resonance.

Simple, they always ask, for what is there OWN weakest point!!!


So: Where is the PROOF from the balcony, .................... silence!
