Running 65-75M.P.H. I've been seeing reading's in the 220's,but then again it's still winter(6-4-09),by the way mine still has the cat.

Why do you care about the temperature ?
When it will get to hot then the pressure will go down and when the pressure will be low enough there will be the red light , and then you have to let the engine cool down while smoking a cigarette and drinking a beer , then start the scooter and fire it up again like a wild horse , that`s all you have to know .
Slow driving is not good for the air-cooled engine , muhuhuhahaha .

PC-V tunned, duell coolers , to up riding, ambient temps high 80s and humidity as high, 230* to 235* cruising 75 to 80mph. Doc

Highjagger · « **Reply #6 on:** June 05, 2009, 09:48:02 AM »

No red light - no worries .
There are other things to care about in this world , like
- who buys the steaks for the grill
- what beer is cool enough to join the evening
- where are the chicks
- vanilla or chocolate icecream
- get a coffee or a tea

Is that syn 3?

My stock cuse4 idles at around 260 in the pan, Mobil 1 Vtwin...metal temp around 360-380

I hope to drop the enrichement tables here shortly and add a 2-1 D&D and 20-60 redline..

My 07 serk idled at around 240 in the pan with about a 13.9 afr flat lined table 2-1 rinehart. Metal temps from 340-380

My 1935 flattie runs around 340-360 metal head temp..straight 60 wt. oil just gets pumped into the primary with that beast.

My 06 tc 88 fx runs about the same...Starting to see a trend..

Road this weekend with with three SERG's including a relatively new one, stock (broken in). Mine has undergone all the Jim Kerr mods. (Cat, fullsacs, heavy breather, SERT). We both had the HD digital oil level / temp gauge. HD #63004-09 Several times we stopped and checked temps. I even jumped off once while we were sitting in traffic to check both bikes. It was a cool day (high 60's) in S. CA.

The stock bike ran between 240 - 270* F. Mine was about 30 - 34* cooler at each check. Have to wonder about the long term effects....

Forgot to mention, I run Amsoil in crank, primary and tranny.

92* here yesterday and humid, 2 up riding interstate at 75 mph average 60 miles and the temps hit 249* at the tank, with twin coolers and a tune I still think this oil temp is still high. Non cat headers and 2.25" full sacs. Doc I have tried differant PCV maps after the tune and the oil temp still has not changed, so it is getting enought fuel and has differant timing in each map, bike runs perfect but cannot get my mind off the oil temps, have check the temps with 3 differant tools all with in 3 * of each other. I have run the coolers in series and in parralle all to be within a few * of each change, what next a third cooler? Doc

Might be time to accept the fact that the bike is going to run a little warmer then you'd like.

Use a good synthetic oil, change it regularly and enjoy your bike.

Just ride em. If you can't stand the heat then sell em. I got 7 years of warranty on mine. When it burns up I will put another one in. When that one burns up I will put something else in or buy something else. I will be going on a 2000 mile trip next week. If it gets too hot then down the road it goes when I get back.

Amen Big T, Sounds like a few runnin high temps (above 145). I ran around for a few hours last night at 70 degree's, Followed a 69 pro street Firebird runnin race gas, Pulled neck and neck to 120. Took a look and oil was 117. I'm stone stock except for Fullsac 2.25's. Still got the cat too! Don't think I have ever seen 140, but if I did I'd go faster and cool er down. Actually Water temp or engine temp is more critical than oil temp. you need a higher oil temp to be efficient enough to burn off the moisture and clearances to adjust. 220 -240 is perfect.

I was able to hook up the Jagg 10 row cooler useing the HD adaptor and some unqiue plumbing. Temps stayed the same as with the HD Premium cooler. so unless the Jagg filter adaptor allows more oil to go to the cooler, do not waste your money, side effect is it forces more hot air from the motor to your leg. This is with the Jagg 10 row vertical mount cooler. Unless I can find a way to make more oil flow thru the cooler, I guess I will have to live with the temps. as the majority of the oil on these 07 up bikes flows back to the tank without going thru the cooler. Lesson learned. Doc

I would consider the Jagg cooler to be a system and would want to use their adaptor before writing off the product. Harley's design is very limiting, and while I don't know if the Jagg is much better I am assuming it can't be any worse. You may also want to consider how you have your crash bar plumbed into the whole system. I believe you said earlier it was in parallel, and if that's the case it may be robbbing flow from the cooler due to tubing size and lower restriction. And yes, placing a radiator or oil cooler up in the actual air flow will cause hot air to flow onto the rider. When we all get to ride the new water cooled Harley's in the near future, all the current talk about heat will be part of the "good ol' days". I still remember way back to my first water cooled bike in 1982; when that fan kicked in while sitting at a light it could get downright toasty.

Jerry

PS. Doc, trust me I fully understand how some things can get under your skin until you feel you just have to do something. But I really think you're worrying and stressing too much over this oil temperature business. The design of the engine is such that 230°F is considered normal oil operating temperature by the MoCo. That is with the bike cruising down the road, not idling in traffic, and at standard ambient temperatures. When you throw in those 90° and up ambients you get where you are, I can see where 240°-250° oil temps would be common. Just keep using the best quality synthetic oil and try not to worry about it. Just think how many folks are out there right now without a gauge and just enjoying the ride (now you know why I don't have an oil temp gauge mounted, btw).

The best oil temps I have had so far is with the stock cooler and adaptor plummed in parralle with the engine gaurd cooler plus the fact that the engine gaurd holds an extra qt. of oil. I use Redline products and have a decent tune, with outside temps in the 95* range, temps were at 250s at cruise with to up riding. I may sound as I am obsessing on these temps but I still enjoy the bike, I am just trying to get oil temps down to get some longevity out of this bike.

Doc, is it possible the flow needs to be decreased threw the cooler not increased? I run across this often with pumps in chillers. Another words the flow rate is to high or fast to allow heat exchange to occur, because it does not stay in the H/X for the desired period of time.

Highwaystar · « **Reply #51 on:** June 21, 2009, 09:52:48 AM »

I agree. I do some drag racing and use restrictors to slow the flow of the cooling system. too fast and no heat transfer. Tight bearing clearances can raise oil temp....

grc · « **Reply #52 on:** June 21, 2009, 10:59:41 AM »

Doc, see what the Jagg folks have to say about flow with their adaptor versus the H-D version. The adaptor/thermostat would be the thing to dictate how much oil is routed through the cooler, and if as you say the '07 and later system isn't routing enough oil through the cooler then perhaps Jagg's adaptor would help. Since you've already gone this far, one more change with the adaptor might be worth a try. And I would still question how much oil is really going through the cooler versus how much is going through the less efficient crash bar "cooler". You might want to temporarily restrict the flow to the crash bar and see if you can detect any temp difference.

BTW, have you verified that the stock thermostat is actually opening fully at the correct temp? If H-D didn't change anything recently, the specs for the thermostat are:

Start to Open - 180°F
Fully Open - 210°F

It would interesting to know the design TD at GPM with ambient rating.

HDDOCFL · « **Reply #54 on:** June 21, 2009, 12:25:32 PM »

With parralle pluming the oil takes the route of least resitance, I know that the HD cooler was designed to slow the oil down thru the cooler with more restricted tubing, but what I see is that both the engine gaurd and cooler recieve about the same amount of oil and it is the coolest temps I have been able to get set up like this. I plan on calling Jagg Mon. to see if there adaptor routes more oil thru there coolers, but I see where its in the engine cases at the oil filter mount that the 07 up bikes have changed to send most of the oil back to the pan without cooling it thru the cooler. I also see it would be a challange to modifiy the HD adaptor to run without a T Stat. you can remove the TStat but it would send even more oil back to the pan without cooling it, the by pass is machined in it and would need to be remachined to remove the Tstat, yes the Tsat is working in my bike properly. Without the engine gaurd cooler the bike will run about 7* higher than in parralle with the stock cooler. Thanks Doc BTW the first thing I thought of was the TSat not opening up. Changed adaptors and it did same temps.

6 hours @ 80mph 95+ degrees, oil read 256, got caught in road const, stop and go, oil went to 266 before we could get off the I-80...... gotta get outta Illinois, the roads suck!

Don't bother coming to Indiana, the cheap bastards here haven't even filled the potholes from last winter yet. Or I should say, haven't filled them with anything other than the cold patch loose fill crap that comes back out after the first two vehicles drive over it, where it then gets deposited on your vehicle. Funny how that crap won't stick to the road, but it sticks like epoxy to the bike or car.

Doc, Thanks for the pixs. Your first of the parallel with the T's said a thousand words. I'm just baffled that a parallel setup is running cooler. The engine guard cooler, is it on the left side? Thank you.

The oil enters one side of the engine gaurd and returns from the other side, this set up allows both the oil cooler and the engine gaurd to cool oil, but the oil will flow mostly thru the part that has the least resitance. Both parts on my bike get hot so they are working. Doc

OK finally got the temp gauge installed, it was 97 here Sat. rode 160 miles most at 50-70 MPH, temp stayed about 190, got into some traffic temp went to 200, so under normal riding conditions I'd say the twin ten row Jaggs are doing their job (as they don't "open" until 185). Having said all that, I believe I have got the temp to stay under 200 during normal riding conditions & that was what I was after (Keep in mind I'm running a 10.5 to 1 compression, not the stock 9.1 to 1. So I'm a happy camper.

Thats very impressive oil temps, Are you also useing the stock HD adaptor to feed those coolers? Thanks Doc

jettjocky · « **Reply #65 on:** June 30, 2009, 09:27:42 AM »

NO, must use the Jagg adapter which runs the hot oil though the oil filter first then on to the coolers, doing that there is 3 & 1/2 less pressure drop than seen when using the HD which runs cool oil though the filter after leaving the cooler.

HDDOCFL · « **Reply #66 on:** June 30, 2009, 11:40:39 AM »

Could you take a pic of the filter, so I can get an idea of how you have it plumbed? Thanks Doc

Don't care for the oil cooler up by the Throttle body, and it also has to send a lot more heat back onto the rider. Bike has extended warranty, I don't, rather me be cool.
I borrowed HDDOC's dipstick gauge. Down intersate @ about 72 for 10 - 12 miles got 209 degrees. Thru traffic and on a longer ride got 235. I am good either temp.
Have a buddy with a 08 96" Ultra with dash gauge with sensor in pan, HD cooler like the ones on our SERG's that he installed. He says 190 - 200 on I-State at 70 and 235 - 240 in traffic (thru downtown Clearwater). So mine and his are about the same.

Good, DW6019 I am happy for you, & by the way, hot motors send heat up to the rider not warm coolers..... in any case I wanted to run a cooler engine with additional cooling & oil (each cooler holds approx. 6 oz. so that's 12 additional ozs. of oil) so that's what we are talking about. Doc, there is no "right" or "wrong" way to install the lines to Jagg coolers, which ever line you select for "in" the oil comes out the other, so to reduce "runs" I just ran from the output on the adapter over to the right cooler then out from it to the left cooler & out from it back to the remaining inlet to the adapter. waaa laaaa. Also please keep in mind you do have to fabricate the right side cooler bracket, as as yet Jagg does not offer, but from their comments to me they may soon make it available. Just take off the one that is installed and reverse and lenghten the arms. If you decide to this advise & I'll provide additional tips by phone. Regards

Jet, I see no benefit to the expense you incurred. Unless your pic is decieving you are blowing hot air back on the throttle body/fins. This is not good, the cooler the intake the better. You have spent several dollars on an unnecessary add-on. Now this in itself is not bad, we all do that every time we buy a bike, you just overkilled a situation, that really is not a situation, in my opinion. You can not tell 10 Degrees of diff in engine temp blowing back on you, but you can feel hot air from the oil cooler, just ask Doc.
Enjoy the two coolers, but I see no need. In 3 -4 years when I buy a new one, the new owner will have no cares about whether the oil temp was 220 or 260. He will only look at the visual condition of the bike. And if any problem pops up in the meantime, warranty will catch it.

Highwaystar · « **Reply #70 on:** June 30, 2009, 08:38:53 PM »

Efficiency dictates ideally 220+ degrees for moisture burn off, proper bearing clearances and horse power efficiency. You can actually reduce engine life with over cooled engine oil. Water temp and oil temp are two unrelated readings. Go to a local race engine builder and educate your self on basic engine dynamics.....think I need three drinks....

HDDOCFL, I guess this can stay as intended, just an exchange of good ideas & information & "opinions" . First if you happed to notice by the details provide at the bottom of every one of my posts I am not running the stock factory lame di*k 9.1 compression you are, I am running 10.5 compression with the other mods listed, I have neither the time or inclination to make my case further with you,, but when you take the position that two Jagg coolers are not required with no technical data to support such a statement (other than your "opinion") it does upset me, as you misinform others that look to this forum for up to date information, not misinformation. When you get a chance pick up a copy of Donny's Peterson's "Unauthorized Technical Guide to Harley Davidson 1936 to Present Vol: 2 Performancing the Twin Cam" He is only the world's most read technical journalist & an acknowledged "expert" by the engineers @ MOCO on HD motors. Very informative, especially the whole chapter on oil coolers & the whole chapter concening all the problems that our 110 motor as had from 2007 to date, with suggestions for corrective actions. (Problems which I might add MOCO has never publicly admited to) Only after you are better informed then I'd don't mind hearing your opinion, as again eveyone has a right to their opinion, but when you express it when you are not informed and it is not based on any measureable data or research then it is a disservice to others on the forum that are looking for better ways of doing things. Have fun with the bike, if you see me on the road please wave, I'll be the one running those silly two Jagg coolers.

HDDOCFL · « **Reply #72 on:** July 01, 2009, 07:43:15 AM »

JettJocky! I never put your two 10 row jagg application down, in fact I am inclined to try it. Sorry if you misunderstood me. Doc

HDDOCFL · « **Reply #73 on:** July 01, 2009, 08:44:06 AM »

I removed the engine gaurd cooler from my oil cooling system, am going to try stock set up for a day or so to see what I gain in temps. I beleive that the engine guard cooler is adding to much restriction to the oil pump and creating a sumping problem, and posibile higher oil temps. will let you know when the rain stops. Doc

HDDOCFL · « **Reply #74 on:** July 01, 2009, 09:24:23 AM »

My attempt with the vertical Jagg 10 row was in series with the engine gaurd as a cooler also with the HD adaptor. I see now that to get the most of the Jagg 10 row I will need the Jagg adaptor from talking to Jett Jocky and Jagg. I will try the Jagg 10 row with there adaptor next. Single vertical first. My first try with the Jagg 10 row vertical cooler was that it deflected engine heat to my left leg, but this may have been do to the fact I ran it in series with the engine guard and that the engine gaurd may have been giving me higher engine temps due to sumping. Its all trial and error with me so far, but I would like the oil temps at the pan to be in the 220s*. Doc

GtreetSlide · « **Reply #79 on:** July 04, 2009, 06:17:30 PM »

I have seen 08-09 bikes hitting the 300 mark. After the last Vtune, my temps are down another 10 degrees and all I did was add a slight offset on the 14.6 to 14.53 at closed loop with the CLB tables (then retested VEs)...

So, my highest oil temp in 100 degree weather is now about 254. Good enough I can live with it.

Now my 02 Deuce 95 on the other hand, NEVER warms up. At 11:1 compression you would think it would just cook. Takes a good ride to get the oil temp up to the 200 mark and the highest it EVER reads is 220... For the life of me I can't understand why the 09 is so much hotter, other than maybe the lean burn in closed loop...

no, I wish. 308 degrees rode 75 miles at 90 degrees. was riding fast (about 75 to 85)

my bike is a 2009 SERG
Reinhart slip on
Heavy breather
2009 non CVO head pipes (no cat)
super Tune

I hope is my LED Dipstick, but I dont think so.

Well I have the cooler back to stock and after riding two up for a few days now, the oil temp is holding at 240s* with outside temps in the 90s* . It is about the same temps as with the engine gaurd cooler in parralle with the HD cooler. Next to try out the Jagg 10 row coolers. Doc

You can do a temp check of your dipstick temp gauge. Check low temp with crushed ice and water, should read 32*, boiling water at sealevel is 212* use gloves to do this. I have checked mine and its of only 1* hot and cold. Doc

jimp · « **Reply #83 on:** August 02, 2009, 12:50:21 PM »

Rode South on the Veterans expressway from Crystal River to Tampa and averaged between 80 to 90 MPH. I stopped before the last toll both and the temp was 256 @ 89 ambient. Bike is totally stock with 850 miles.

jfh · « **Reply #84 on:** August 02, 2009, 03:11:19 PM »

I am experiencing 210-215 degrees after an hour of cruising in 90 degree ambient temps. Temps will climb to 230-240 when stopped in traffic but quickly cool when moving again. Those same conditions would produce temps in the 250 range when the mods were limited to catless head pipe, Fullsac 2" baffles, and SEST tuner.

Since adding Axtell jugs and flat top slugs, S&S 585 cams, SE 58mm TB, Dewey's Pro Street porting 10:1 CR, TTS Master Tune, and replacing the stock H-D Premium cooler with twin 6-row vertical Jaggs in series on the down tubes my operating temps were reduced at least 20 degrees. As this was not intended as a science project, I did the above mods together and cannot quantify how much any single one contributed to lowering the temps, but I suspect the long exhaust duration of the cams and the oil coolers had the most cooling effect.

I am very happy with the current operating temps.

8 hours non stop 65 to 75mph with 80F gave me 222F oil temp that dropped to118 in town. 2/14 Fulsacs, ceramic coating and Head Quarters Pro Tuner. Engine was completely heat soaked after 8 hours.

I have added the Jagg 10 row vertical oil cooler in series with the HD preimium cooler , And with out side temps in the 90s* getting 240* two up at 75-80 mph, around town hitting 255*. Best I have gotten so far. Doc
