Just curious since I have these mains in my 700.It does'nt seem that yammi has a jetting chart.I have been checking my plugs after some hard runs and there certainly safe so far, kinda dark brown and slightly black.This weekend its supposed to get really cold, possibly below zero for high here in michigan.I'll be checking my plugs, but am wondering what some you guys experiences have been and how cold you have ran a sx 700 with these main jets, by the way my sled is stock just Turks clutching and the needles are lowered a half position also.Any help would be greatly appreciated.

i ran mine down to -35 celsius with no issues, but it was pretty crisp sounding so i would say it was on the edge or a bit lean, but i ran it like that for 3 or 4 years with no trouble

Cool, any idea what that is in fahrenheight?I can't remember what the conversion is.
142.5's is what i have in my 700SX for the last 5000 miles. Ride out of Gaylord area and Muni.

Thanks fellas, I agree -31 is very cold, that says that factory jets are safe to silly cold temps!Tod, I live in grayling and ride to gaylord often and have been to munising many times also so I know were riding in the same type elevation.
I run 147.5's in my sx ,but it is triple piped.Its safe to 0* . I ride gaylord all the time. Am goin to UP this weekend....probably should put my shelf back in! You should have no problems if your stock.
Stock? I went down to 141.3's and a 143.8 for alot of miles, coldest I'd guess -5. I'm also running 147.5's w/ pipes now and I did see sub zero temps last year.
