temp light came on after 9000 miles ....so i checked coolant resevoir...it was low.....i decided to do a replace the coolant completly. now ever since .....the light comes on. i took a hundred mile ride and had to add 1 cup to the radiator and one cup to the empty resevoir.....i checked cylinder temp with a laser temp gun. it says 250 TO 260 will this temp damage my engine? the bike is like new ......i dont know what is going on? it hasn't leaked or perged out a drop? i dont think the fan has came on either. this bike is a 2011 c 50 boulevard. is there any other systems connected to the temp gauge? it seems to ping at times and loose power.....then the light goes out and regains power?
