Hay guys and gals,
my blaster has been working real well so far but i wanted to know if I should change the jetting when the temp drops from 90* to like 50* down here in florida????Also do you need to re-jet with a new rad valve???

 

I would not worry about it. Just put a new plug in it before you ride in the "extreme" cold and look at it after you ride. Yes you will need to re-jet with the raad valve.
