my answer might not be 100% accurate,
but my advise (from experience) is that
once u see the red light there, it means ur 2T is low
level...
dangerous to rev up, so its advisable to ride at a low speed/rpm,
say 1-3 km, PLS LOOK FOR A PETROL KIOSK N BUY 2T !!
i suggest dun ride more than 3km, god knows whether ur 2T might
have finished liao
that time i got kena b4, luckily i got a bottle of 2T in my box,
continued about 1-2 km slowly to a petrol station n topped up
there...
