Low Temp Jetting

[88 Turbo Coupe]

For winter riding will I need to change the size of my jets on a 2 stroke?

yes, the cool air is much more dense, so you need to fatten up the jetting. I've read that for every 15 degrees of temp change, it is roughly one jet size.

It probably wouldn't hurt to richen it up a bit. You could no doubt get all of the adjustment that you will need out of the needle and the air/fuel screw. Most people tend to run a little fat on the mains and they aren't a real big factor unless you are riding at 3/4 to wot most of the time.:naughty:
