      What is the temp range that I should be comfortable running? I am new to karting and yesterday was running about 125 F. Also does the Rotax class restrict moving the radiator to the left side of the kart away from the engine?  It seems it would be easier to change the main jet without it in the way. And can the radiator be upgraded to larger if want cooler temps without violating Rotax class rules?

      You were a little light on temp. 145 to 165 should be good.

      The answer to you other questions, no. Check with the association that you race under to see if they allow it. Rmax rules state the engine and all of its ancillaries may not be modified.
