Fairing lower increased temps.

I recently put a set of vented lower fairings on my 2012 Road Glide and now I feel like my legs are catching on fire. I also noticed that my air temp intake gauge is reading near the 100 degree mark on most rides where the temp here is in the high 80's. I have the vents wide open and added a set of mid frame air deflectors with no change. The service guys tell me the bike runs about 12-15 degrees hotter with the fairing lowers and its no worry. Anyone else notice this drastic change? Wondering if I should also go to a more open air cleaner? I have a Kuryakyn Hypercharger right now.

I would just remove the vents. BTW, I don't want to rain on any parades, but the hypercharger is more for show than go, if you want the engine to breathe better, there are many better A/Cs.

I thought about removing the vents also but didn't think it would give me that much more air. Will give that a try. Yeah looking for a more open air cleaner that works with lowers. Gonna get rid of the Hypercharger I think.

remove the vents

may be a bit hotter with the lowers installed , but my unscientific opinion is that you are probably getting more forced air flow to the motor with the lowers than without

I've ridden my RGU with and without the lowers on. Personally I like the wind protection with them on. Yes it's a little bit warmer but not enough to cause discomfort or damage to the motor.

2011 RGU with more money then sence in it.
Oh and its black because blacks faster.

Having lowers on your RG is not going to cause any heat concerns for the motor. Lowers have been on the EG Ultra for many, many years and came on the RG Ultra the three years it was produced. You may notice more heat on your legs from not getting as much airflow, but the temp difference to your engine is negligible. As others have said, you can completely remove the vents if you choose to. Depends on your riding style. For those of us who ride rain or shine and the lowers and vents provide good protection.

The fairing lowers won't cause the engine to run much hotter than normal but those mid frame heat deflectors are heat traps and removing them will improve air flow to the rear cylinder and let the rear cylinder run cooler.
The reason you feel the heat more is the lowers create a vacume and draw the engine heat forward before it can escape.
I usually run my hard lowers and pull the vents in the summer but this year here is AZ it was too hot (temps of 105 to 118) and I had to pull the lowers off.

Thanx for all the great feedback guys. Pulled my vents off today so we will see how it feels at Street Vibes in two weeks. Reno will be warm!

you won't notice much of a difference if you're stuck in stop and go traffic. for the vent removal to actually make a difference, you gotta be moving. (now this is all said with the caveat of never having been to street vibes, but assuming it's gonna be a crowded affair).

the lowers actually help your engine to run a little cooler by funneling air over the cylinders. unfortunately, that hot air has to go somewhere, and that is usually over your legs. i remove the vent doors every year, and put them back on for the winter. i find that the extra heat with the lowers is well worth the extra protection/wind management that you get.

I understand the concept of reality, but find it too confining for a way of life.
