2 stroke engine temp

So was -28 today and deep snow my 250 sx has a avid carb heater lectron and 130 thermbob. My temp was 106-119 all day can a 2 stroke operate at these temp with no problems bike seem to run fine the same as when it running at 137-157 on -15 day and not as deep of snow. Should I start to cover radiators and would that help on cold days. What is max temp a person should run a 2 stroke 200. I have never had temperature gauge before and was not sure what bike was running but does seem to running good with modifications I have done.

Covering the rads definitely helps. Those temps aren't too bad though. Engine shield? I would be concerned at 200 and stop to cool off. What temp does your bike boil over at?

Not sure never has boiled over. Past rides have been spring conditions in heavy snow and bike runs 160-190 all day and ran great with no boiling over. As long as under 200 I think is fine and should not hurt motor from past few ride at +10 and heavy snow. Going wide open with the wind seems to cause the higher temp turn around and run into the wind temp drop 20.
