winter jetting

[stogy3]

I have a stock 2002 and winter is coming here in NH quickly and I want to stud the tires and ride her on the ice. I was told to make sure I jet the carbs and someone else told me not to worry about it because I havn't touched the jets that came in it so it is probably running really fat anyway (I think he is saying rich). She starts 1 or 2 kicks every time cold with the chock hot w/o. Smokes like crazy at first then as it warms up smokes less. I do not know what size jets are in there know and I havn't done a plug check yet. Do you think I could leave it alone?

There's no "written in stone" jetting for winter riding. You need to learn how to read your plugs and how to do the jetting. Only you can be responable for your machine so that it doesn't blow. Chances are, that you will need to do some changes to run in the winter. I know on mine, that changing the needle position is not enough. I have to run at least one size bigger on the mains. Read up on how to jet and how to read your plugs, do a search. Go buy a couple sets of new plugs. 30-40 degree temp change can really change things, if your still stock and it ran fine at 80-90 degrees, you will need to rejet to run at anything below 30.
