Default Lowers and oil temperature

Has anyone seen a significant oil temp reduction by removing the lower fairings? Coming back from Florida yesterday, I was right at 225* doing 75-80 up the interstate. Never would get any hotter, but that was about my limit for comfort. I told myself that I would pull over at 230*.

I live in Florida and ride in temps well into the 90's with my lowers on. I do open them up though. The hottest I have seen my oil temp is about what you had. It looks to me like the lowers actually funnel air to the engine rather than block it. JMHO

I wouldn't consider 225 too hot at all.
Were your vent open?

I consider 300F hot, 250F normal, and 230F as OK but cool. The thermostats on my air cooled BMWs don't even open until 220F and normal is around 250-260F.

I'm out here in the AZ desert where during summer we wish for the 90's. I've ridden with my lowers on when the temp. was 118 and the bike never got above 230. I do have an oil cooler, I don't know how much it really helps though.

I pulled mine from my 07 UC and it did lower the temp. You better get use to the heat: as previously stated: 250-275 is normal summer temp. If 230 is your "popping smoke" limit, your bike will sit idle this summer.

Normal operating temp. don't worry until you start approaching 300.

If 230 is your "popping smoke" limit,
Popping smoke, I haven't heard that phrase over 10 years(when I got out of the service).

I live in AZ and commute to the Phoenix area year round on my Ultra. I leave my lowers on, and as a matter of fact, I don't even open them, as they seem to channel the air to the motor better in the closed position. As others have said, I wouldn't worry until oil temp goes quite a bit higher than 230. My guage reads around 250 cruising uphill at 80mph in the heat, I consider that normal.

Teu

P.S. I likely would not be comfortable with a fossil oil at those temps for an extended period. I use a syn, and change at 5000.
