Where can you road race that flying bomb on "public roads" in Japan? <grin>

Hi Ross,
I rebuilt my J2 engine (847cc) at the compression ratio of 7.48. Theoretical
CR after
8psi supercharging is about 8.6, and could win a couple of Vintage Car Races
recently,
using ordinary pump petrol. It has my own special lightweight pistons and
can rev
up till 7000rpm. It produces about 60bhp I hope - rather optimistic, but it
is actually enough
for 1060lb dry weight road/racing J2771 with ENV box on public road.
If you want I can send calculation chart of S/Ced compression ratio.
Good luck,
Hiro Nishio
Kobe, Japan
