Sorry, dunno hokkien ... but let me clarify the 2'nd question
... when in normal gear and want to change gear to 1'st, I must
hook the power by accelerate the RPM until 3500-4000 then I release
the cluctch, if not ... then my motor sound like "tot tot tooot"
like that ... sound like pity like that ... I dunno ... sometime I
just hold the acceleration handle (not increase it), take about 3-5
seconds until sound "vroooom", but sometime not "vroooom" instead
of "tok tok tok" like don't have power, and then must really
accelerate until "vrooom" ... Is that something wrong with
adjustment of petrol and air chamber?
