2018 KTM 450 Per subject. Installed the C3 Thermostat, temp gauge, and Heated bar kit along with a PST wrap. The first ride on this setup was today and we had REALLY deep snow (Pushing over the fender in places, or kicking over the bars) About 2" fresh on average. On the trail, the bike will run 170 - 180 with heated bars on full and it's perfect. As soon as I jump off into deep snow, temps plummet. 100 - 120 TOPS, and sometimes I even saw 90. YIKES. I had to run with the bars off to keep some heat in the motor.
My riding buddy on the same bike but with Carls Cycles in-house setup installed never saw below 150 all day in the same conditions.
Observations:
The Left and Right Rad get warm/hot LONG before the thermostat should open up. I have a tusk radiator cap installed and it matches temps with the TSS installed in the thermostat housing. They basically match all the way up to 180 when I let it idle in the garage. The routing of the plumbing is exactly the same as OEM, and matches the first pic more or less. The actual install pics are below. The rate of temp increase and the fact the rad cap and TSS match make me think this is not just convection.
The radiators were packed with ice. (PACKED). Is the rapid cooling is from shock cooling due to the snow load hitting the radiator or ice building up in it.?
It was recommended to me to use either a rad shut-off valve and/or radiator covers.
Thoughts? REALLY don't like the motor running this cold and I don't want to hurt it.
