The owner say's it helps somewhat. I personally don't care for the looks. Besides that, I'm coming off a Road Glide with a 128 kit so heat doesn't bother me much.

 

I can't speak of the Pan America but my SV1000S is a 90° twin, water & oil cooled & it will read 225° in traffic at times. I don't notice alot of heat on my legs but seeing the temp get that high is unnerving.

 

The boiling point of the coolant is something like 265F. No need to worry unless it gets to that point.

It's meant to run hot. But I agree a cat delete would be good.

I just look at it that at least I wont be getting cold feet in the winter.

 

Maybe other factors involved, such as high humidity in FL, but I keep noticing the big difference in heat from the engine and pipe based on difference in ambient air temp. At low 80s and below engine heat isn't really noticeable. High 80s and above its roasting the crap out of my foot and right calf anytime the bike isn't moving over 20 mph. Engine temp on the display doesn't vary. Its the felt heat that changes. Am I crazy? Can such a small change in air temp make a big impact on heat coming from the bike?

 

Well yes if the fans are running more often.

Does anyone know if coolants like Engine Ice would make a noticeable difference on this bike? What about Water Wetter?

 

The coolant additives probably won't help with the heat. The thermostat will keep the engine at HDs desired temp.
Only if the bike is running hotter then design or overheating will the additives have any effect at lowering the temp. They are designed to aid the coolant in transferring heat to the radiator where it can be extracted.
