Way back in October at a local sand pit i somehow managed to completly F...k my rear end. The swingarm bent kinking the back chain and blew the axle bearings right out of it. Then it really made my day come to find out my axle housing was bent as well. Wasn't that a fun week. Here we are now, 4 months later and she's back. After getting a new axle housing/bearings and my swingarm fixed im ready to role. I had my swingarm straightned until my new +3 gets here from Blasterzone.
I took it out last night on the ice and the snow and it sure does feel good to be doing that again. The ping of a 2-stroke is like music to my ears.

Anyways, back to my question, Sence it is the middle of the winter and its about 20 degrees colder here then the last time i re-jetted it, what should i do?

Go up atleast two or three jets. Check your plug. It should be a gray color. What jet are you running right now? I have the same mods as you, and I run a 290 main, and its around 20 degrees at 800ft above sea level.

290. But it is about -15 right now and the last time i re-jetted it was about +30, so there is quite a difference. Going up on the jets, what dose that increase, the air or gas?

what sea level are you at? if its that cold out, i would still only go up no more that 4, but i doubt that you will even go that high. What jet are you using right now. Just look at the plug, and go from there. When you go up jets, you run richer, which means you are getting more gas for how much air you have. When its cold out, the air gets thinner, so you get more in. Therefore, you need more gas to keep your mixture the same. When its warm out, the air gets thicker, and you get less air in. So, you go down jets, so that you get less fuel. Hope that helps.

Man the sea levle around hear dont change much, I have heard you guys on hear befor tell me that you would have to re-jet, if you went from your house to a ridding spot, We usually set our jets and they are good for like all of NS haha

I was asking what sea level at to see the diff. between where i am and where he is. If he is around 800ft. he could use my jetting a 290, as an example of where to start.

I don't mean to correct you, but you mean what elevation not what sea level. Except for the tide which is not factored into elevation, sea level is constant and considered zero elevation. From there you have above sea level and below sea level. Again, sorry for the correction, I know what you meant.
