Last weekend I was returning from a trip to Milwaukee and I thought I would try to compare engine temperature with the lower fairing vents open and closed.

 

And???

 

I hate when aliens abduct folks when they're trying to tell a story........

 

I hit enter and it posted.

The long and short of it is I used the power vision to watch engine temperature with the vents open and closed and saw no significant difference. I would like to know if others have done that and found the same result.

I would also like to know if anyone has compared ET with lowers installed and without lowers. I know I'm going to have to do this, but it would be nice to see others that verify what I find.

 

My RG runs cooler with the vented lowers on.

 

I compared lowers on/off

105º ambient

loop: 1 mile at 30 MPH to fwy- 9 miles at 60 MPH...off, on to ramp...9 miles at 60 MPH, 1 mile at 30 mph.

first rode the bike to get to operating temperature.

removed fairing lowers

then did loop 1

put on the fairing lowers

then loop 2

measured at the oil dipstick, temps were 25º lower with fairing lowers in place

He must have fallen asleep.

 

Thanks, When I look at the lowers, it seems to me like they funnel air into the motor. But I've heard a lot of conflicting information on the subject. It looks like you went about it in a very systematic way.

 

part 2:

the increased air flow across the motor may result in more heat removed from the motor...but directed at the rider especially the right thigh- the "blow dryer effect"

that's ok, I'd rather my motor be happier, I wear thick jeans

using the fairing adjustable deflectors to direct air into the cockpit does help

True, but if my little experiment holds true, opening the vents has little affect on engine temp and definitely makes for more rider comfort.
