re jetting carb

[waterwolff]

I have a 94 polaris 300 2 stroke do you have to rejet the carb when going from warm weather to cold weather

[knoppers]

I was woundering the same thing, but I have a 4 stroker.

You should not have to.

Dave is right, about the only thing you may need to do is adjust the air idel setting so it will start easier.
If your into top preformance you may want to start adjusting the jets, but to just have a reliable every day ride I would just let them be.
Jetting can be a pain and can cause your machine to melt down if you don't stay on top of the settings as the weather warms back up.
A machine set up for warm weather preformance will run richer as the air temp gets colder and thins out.Causing the air fuel mixture to have more fuel than air flowing in.Warm air is dence so you have the reverse effect, more air less fuel so now the motor gets hot with less oil rich fuel to lubricate it.
All the oil does is lube the piston and crank bearings, a four stroker has oil in the crank case to lube the bearings and the fuel then cools the cylinder.

Thus a four stroker has no real need to adjust any thing.

Now a modern 94 year 2 stroke should be set up to run in most temps we see here.

Had a 1995 300 polaris 2 stroker, never rejetted it once or adjusted the mixture screw, never burnt it down.

ride safe, wear a helmut, stupid hurts

if you get it serviced, wash'em first.
