This page lists speeds for US and UK versions, which is perhaps
a bit more of an upgrade than just the carbs:

It doesn't list RPM, but that should be an easy calculation.
Mine has reached about 5400 in fifth (108 mph est.) before I
chickened out. With a suitably crazy driver, it should do
almost 120 mph. Very far from stock though...
I would never encourage anyone to go that fast on a public road,
especially in a spit. It really feels like it is floating over
a hundred.
