Cold weather tuning

[suprex]

o.k.... it's below 20 degrees here in nashville ( yes, i know.... that is warm to some of you). i want to ride... but...

do i need to adjust my air screw? in or out? when it gets cold do i need more fuel or more air? i am kinda lost... i just don't want to screw up my blaster.

i hear people saying you need to jet properly for colder weather, or am i reatarded?

you need more fuel... because coold air is more pure

I was told to rejet during winter by my local yamaha dealer...

so I just waited and got my F7 pipe. then rejeted
