I see nothing in my HONDA factory Service Manual stating horse power of
a stock S B 50 Elite scooter(49 cc). If this mentioned muffler gave a
10% increase(being generous)equaling 8 HP,than Seems a stock (mine)would
be in the range of 70 to 80 HP as it is.WOW,can I get duals ? lol Please
give dyno figures if available.Seems we are looking at a 300+% increase
over stock.My speedodmeter reads 30+MPH ,up hill with my 220 lbs on it.I
am "leary" of that reading, a bit high,and Stock using 87 Oct fuel.
MAY YOU HAVE A BLESSED DAY,AND EVERY DAY.
