Warm Right Boot

[SXRPILOT]

Last ride of the year on some fast trails in Northern Ontario and boot got very warm. Chain case was pretty warm and oil tank was hot enough you couldn’t keep your fingers on it. Engine temperature was good. Is all this heat transferred from the exhaust and turbo or should I be looking for something else?

engine oil helps keep engine cool as well as lubed. never measured on a sled but would see engine oil temps of over 100 c with dino oil in my 10 silverado when pulling hard. with synthetic i would worry if it hit that temp.

as the conditions where keeping the coolant cool, i would say the higher air temp helped bring it up that high with how the air is routed through there. if you where running it with the panel off, it would not have been noticed by you as it would have had more air flow. most likely have not hurt anything.

I have had my right boot get very warm when the fuel quality is poor, the engine detects misfire i believe and adds more fuel, and the muffler gets very hot. did you burn more fuel this trip out? is there maybe some soot around the muffler or by the cover vents? I have yet to see any negative effects yet. but i havent pulled my engine apart either.

On a hot day how fast were you riding? These motors do get hot, it’s a motor, they get hot especially on a warm day.
My truck gets hot when I open the hood on a warm day , these are motors, you could take hood off and it will still be hot. It’s the nature of the beast, I just had to say this!!!

Trust the temp gauge. If things are to warm you will know based on coolant temps.. My last ride I was running in upper 30's and low 40's and my coolant was running about 3-4 degrees warmer, but the minute you stopped or idled it would rise FAST.. In cold temps you don't see the big spikes in temps.. I always have the temp display up on mine.. Now if you had some HOT oil on your right boot that's another story? DAMN that rollover valve!

Imo it's Normal especially if you are running a stock muffler tune..
I know the trails in beautiful northern Ontario and they are big and fast. Looooong 100mph pulls does create heat
I added moflow vent to the front and one at my knees. Also plan on getting the header blanket to cover my header

It was hovering around freezing that day 0*C. 20-30 minutes of speeds constantly over 100kms. Sounds like heat transfer, it was the last ride of the season so I wrung it’s neck. Time to replace fluids, thanks for the feedback!

I'd say all normal. Engine oil temp returning to tank is approaching 200 degF, hotter than coolant which is around 170 F. Then, add heat from muffler right in front of both tanks. Most oils are synthetic these days and can easily handle 275+ degF with no degradation in performance at all.

I like how you added adhesive heat sheilding to your tank..(I seen a pic you posted somewhere here on ty)i plan on doing the same to mine

i get hot foot as well. Probably because I burned out muffler. I put heat shield tape on everywhere I could, which helped a lot but next year I will be covering turbo with tomcat and heat tapping the exhaust for sure.

I thought the factory heat shielding was minimal and flimsy looking considering how much heat tank is exposed to (even with the stock heat shield in place). It's plastic! And, it doesn't cover the whole front of the tank. I used way better adhesive-backed insultation and covered the whole front of the tank. I also put some on the inside (facing engine/exhaust) of the chain case, and covered that coolant line on left side. Also used same stuff to cover oil tank and chain case surfaces that face muffler. Also insulated the stator end of the engine that is right next to muffler. Anything to keep heat out or reflect it away.

Looks like this muffler has been pretty hot.
Had to stop before and put my right boot in the snow to cool it down.
Hp makes heat.

The TD Turbo force muffler does not get hot. How do I know. I put a hot dogger on it and it wouldn’t cook my food!!! No BS. I have vents up front maybe that’s why? Frog skin vent upper right in picture.

I just put vents on my summer project list.
