Todd,

You have some great advice in all the input from the gurus. Let me see if I can organize it in a logical sequence to help.

First thing to do is determine what gauge you are going to use to make your decisions. Use the IR gun and shoot the radiator at inlet and outlet necks. If the surface you are shooting is not black, then spray it with flat black paint to get the most accurate reading. You could also measure the outlet of the water pump. Now that you have confidence in the dash instrument of choice. You can decide if you have a cooling problem or not. If you want another confirmation, open the radiator cap, and insert a digital thermometer. It's well established that most of us don't trust the analog gauges on the dash any longer. So, you need to affirm if the digipanel is giving you good info.

Second, cleaning the radiator is never a bad idea. As others have said, don't go crazy with a pressure washer or you'll bend the fins.

Third, use the shifter and keep the RPMs up on the climbs. The two stroke engines do not like to be lugged (low RPM and heavy load). Running them at higher RPM helps with cooling in two ways. The obvious is that it speeds up the fan. The less obvious is that higher RPM pulls more air through the intake and out the exhaust. That increase in air flow through the engine has more effect than you would guess.

Sorry, for just repeating what others have said.
