I am not sure why or where i read it, or if it is even accurate, but we try and keep it below 220,You run a different belt in your SxS than a sled obviously, but what temp do you feel is the limit for the belt? Is there some consensus in the SxS community about what is the maximum allowable belt temp?
Generally it is around 140-180 until we are running in snow or something of the sort.
