hmmm.. both batches (FP; the others) have the [b]same
power specified on the tech sheet right, which
theoretically means that they should attain the
same top speed...
this is not aimed at anyone in particular, but does anyone think
that the SP is electronically limited? via the speedometer input to
CDI? which means even if i:
1. use a tuned exhaust pipe (unobstructed, tuned expansion chamber,
straight-through stinger),
2. "racing" carburettor (can be large or small depending on whether
you're talking about maximum airflow or air velocity in the
venturi), + a proper rejet,
3. high-flow air filter (or none at all),
4. sprockets optimized for top-speed (something super big in front
and super small at the back, e.g. 16 front, 39 rear, even if it
takes me forever to reach top-speed),
the later SPs will still max out at 170-180?
there're many ways to tune for power, but just listing a
few...
hmmm.. my humble opinion is that 2B bikes won't be electronically
limited, given the low accuracy of the front-wheel driven
speedometer... the "slower" SPs could result from LTA imposed
restrictions on the bike, like restricted exhausts, smaller
carburettors etc...
interested to hear your comments... eh sorry for side-tracking...

actually, we dunno oso. that time we heard it's something in the
filter that causes the restriction, he later got some power
filters, not sure KNN or ah boy, and changed the muffler. made his
bike sound unique, till this day haven't heard that many SPs that
sound like his. it increased his pick up but his top still remained
at 180~5
