Is the engine temp even relevant? AFAIK, there aren't any mechanical issues related to engine heat with the Rushmores or the M8's.

There's a guy (MilesOfTexas) on the Rushmore forum that just turned over 100,000 miles on his un-modded, un-tuned, non-de-catted 2014 Limited with no engine problems at all.

I'll never approach that kind of mileage on mine, but I'm goin' with his attitude regarding just keeping it stock & not worrying about it.

 

The engine temp for any engine is relevant. The cooler the engine runs, the better it runs and the longer it lasts.

 

I use my hand for temp check and can tell you the M8 runs cooler than my TC did.

 

Just ran my first Vtunes with TTS on my 2018 Roadglide 107.Air temps mid 50s...ran a datamaster histogram when I got back and engine temps stayed in the 345 degree range all the time.I noticed my lower vents were closed so I opened them and will go try again today.Seems awful hot. Bike is stock (cat removed) with stock mufflers.

 

Seems awful hot for "345 degree range all the time"! I'd be worried about sumping and have it checked out. when was the bike built? Before or after mid Oct when the changed the oil pump again?

 

mrg date 11/17.Bike runs perfect and no issues.

 

How many miles on the bike and whats the furthest you've ridden in a single run?

 

1200 miles First run with Vtunes was 100 miles.Gonna head out again now and check it further.Will post results when I get home.

 

Keep your lower vents open regardless of the temps.

 

Rode 96 miles and came back and read flight recorder.Ran another Vtune histogram...staying around 330-333 with lower vents open.Seems to run hotter than my 110.Kinda scary.
