It has been hot this week in Reno (mid to upper 90's) yesterday my oil temp 247 degrees.

 

I've been riding in 105*F and higher temps the past few weeks(and will for the next 3 months). No oil cooler, no oil temp gauge. Everything works as designed by the manufacturer with no loss of power, no loss of oil pressure, no noisy lifters, no unnecessary detonation, no sky falling, no earthquakes/tornadoes/volcanic eruptions or anything else that is apparently prevented by installing ultracool coolers.

 

Oil needs to get above 212 degrees to boil any water caused by condensation out of the oil.

It is best to keep you site on a range for oil temp as many variables come into play. 230 is center point on the oil gauge from HD.

Overall running well below 200 or over 290 should be a concern.

230 is a good target number and seems to be where the engine is designed to run most effectively.

 

=============================================

All you guys are totally missing the big picture here which is even at 230-240-250 deg oil temp hds are in fact already suffering significantly perf wise when oil temps running 40-50 deg hotter in the 230-240-250 deg range in summer heat vs my hd's motor with oil temp 50 deg f cooler.

That makes them much more liable to detonate,they in fact loose sig pwr/trq & throttle response,valves/lifters make more noise,oil pressure is approx 10-12 psi lower @ idle & cruise,hot starts like post fueling up are harder & slower all of which are a thing of past post reducing oil temp 50 deg in summer heat on my 09 hd.

heck,prior to cooling my bike oil pressure in summer heat was 7-8psi @ idle & 32-35max @ cruise with fresh oil change,get 3k miles on the oil and take another 1-2 psi away from that & oil pressure at idle was in the gutter like 4-5psi max.

Post installing the 2 cooling mods reducing oil temp 50 deg f in summer heat oil pressure is not much better being a min of 18psi @ idle & 45-47psi @ criuise in 90+deg f summer heat which is a huge improvement.
the 50 deg f oil temp reduction also puts the oil in a position to not be stressed 7 or sheered as much in summer heat too which will keep it protecting the motor better till its changed too.

That all made my bike feel ,ride & perform like a totally diff bike when riding in summer cond of approx 80deg f or higher (esp in 90-100deg f heat) making the bike & motor much more responsive when i hit the throttle in summer time cond along with also being more comfortable overall to ride too due to less engine heat hitting me & the wife while on the bike too.

And when in cooler riding cond /temp all i do to ensure oil temp warms up to where it should be in simply turn off the switch on wards fans and if i need more heat for oil & motor in real cool riding temp have a custom cover that takes approx 5 seconds to slip over the oil cooler.

I have never had ainy issues at all my bike or classic car (owned & driven since 1978/approx 38-39yrs) with oil & or coolant temp running in 180-200deg f range in late spring ,summer& early fall cond here in NY state with respect to condensation buildup in crankcase etc .

I have had the v-covers off the bike and classic car (69 396-BBC) many times over the yrs with no sign at all of issue like the milky white crap that builds up when you have moisture issues in oil/crankcase/motor in general that you will see on heads with v-covers off of in oil when you change it too.

Yes hd states 230 deg is norm oil temp to see on an hd but the oil temp quickly rises above that in summer temp above 80 deg f esp in traffic or at slower road speed esp on an hd like my 09 flhtcu with batwing faring & lowers etc.

In 85-90+ deg f summer heat with the 2 cooling mods oil temp on my bike is approx 190-195deg f @ cruise & go's to 215-220deg f in moderate traffic post sitting at 4-5 traffic lights in a row along with a little slow moving traffic too.

And the motor on my bike performs much better in 80-90+ deg summer heat when cruising @ 190-195 deg f oil temp with the 2 cooling mods i have vs when oil temp used to run 230deg f or higher,thats for sure which i have experienced 1st hand in both case with & without the 2 cooling mods so know for a fact its true.

But as long as you guys keep completely closed minded you will never get to see & experience for yourselves all the great improvements in engine perf
& riding comfort i now have on my bike all the time in summer cond post installing the 2 cooling mods at the same time on my bike that all you guys think your hd's wont benefit from at all or not much when you couldnt be any further off the mark or wrong about because you never tried it therefore have absolutely no 1st hand exp with it on your hd's till ya trying like i did.

I go by results and posted the actual true results i got on my bike mult times post installing the 2 cooling mods @ the same time ,but all you NEY Sayers are full of bologna & dont know what your talking about because once again,none have you done or tried what i did so you cant accurately comment on it till you in fact try installing the same 2 cooling mods i did & rec that reduces oil temp 50 deg in summer heat on your bikes .

Then & only then will you Neh Sayers actually see & experience for yourselves just how well your hd motor responds to the oil & motor running much cooler in warmer summer cond which most of you that are POOH POOHING the idea your hd could benefit a lot from cooling the oil & motor like i did have yet to try.

All my posting on this subject isnt opinion that can sometimes be on target thats just as often not on target which is the case here for the guys that are commenting on something they never did or tried which is simply BS at that point.

Enough said!/LOL!

And Happy motoring in 80 deg f or higher temps on your HD's w-roasting motors that lucky for me is now a thing of the past on my HD!/LOL!!

Don't get too hung up on temp numbers. Just avoid situations that causes excessive heat on the engine and enjoy your bike.

 

^^^ Bing Bing Bing ... We Have A Winner ^^^

 

Don't sweat it, ride.

 

Wow...

 

Huh? All Rushmore touring bikes have an oil cooler or in your case, radiators/liquid cooling. We all do things we like to our bikes, additional cooling makes just as much sense as a fuel processor or air intake as everything works as the MOCO designed.

 

Huh? Where did they hide the oil cooler on my bike? The twin-cooling does virtually nothing for oil temps.

My post has nothing to do with 'doing things we like to our bikes'. It was a sarcastic response to the ever present diatribe on how we're all riding performance reduced bikes due to our lack of ultracool oil coolers combined with engine cooling fans. That long-winded post is every oil or engine cooling thread on this forum.
