Pretty sweet motor.. 58cc though? Are they sure?

Two stroke Tuners

I've got a 58cc cylinder/head/piston that I used to replace the 48cc I had.
Here's the port timing specs on it:
117*ATDC exhaust (29.9mm down), 134* transfers (34.1mm avg), 17* blowdown, 62* intake (58mm), .6mm deck, 45.6mm piston length

Thanks for the presentation of the old Gordon Jenning's Two Stroke Tuner's Handbook and the MicroCar Project info, Jaguar.

I had bought that book way back when I was off-roading with a DT-1.
Should probably get another copy for use on these china engines.

I'm looking for the best 20-30mph I can get from this project. More speed and noise would only draw unnecessary and unwanted attention.
Must learn to build a long, quiet pipe with a broad powerband.
First mod will be a longer intake tract, probably because it's easiest.
Has anyone compared them to boost bottles?

Suppose it might be better to start another thread or PM, than hopping on this thread???
Tnx
