11' 250 race-wa. jetting?

[adv rider]

New to forum, picking up an 11' 250 race this week. I am wondering about what jetting people are using here in Washington? I have been on a 4 stroke for last 7 yrs, happy to be back with a 2 stroke. But I am worried about the jetting, as I plan to go to desert 100 with the new bike. I am hoping to get the jetting close and usable- I don't want to foul plugs or burn up the engine. I will probably get to ride once at Walker valley before the Desert 100
I did a search, but did not find what I was hoping to find
Thanks for the info

temps can range from 30-60 degrees, and elev from 300-1800'
