hi guys thanks for all your advices...really nice of you all. i
realise it might be becoz it's when i just started the bike, the
engine is still somehow 'cool'. coz when i leave the engine on
idling for a while before i clutch in first gear, or ride it for a
stretch of road without stopping, this problem is no longer
there.
This is normal rite?
haha, guess it must take quite a while for me to get used to this
bike. 
yup, i just start riding for a week +
