hello
my rt125 was not running well early this summer
had to always carry a screw driver and drain the float bowl every time i fueled up
found a station selling 90 OCTANE REAL GASOLINE...
i still carry the screw driver
BUT HAVE NOT USED IT IN 5 MONTHS
and the bike runs like it did when new
not very fast but GOOD
it gets better mileage on the real stuff also
and it starts after sitting for a week or more without a big fuss and or priming it
