Made up last night.Old small junk oriental bike cooler.Taped off return oil line to tank.Tested 30 miles 75 F. at testing time outside .Runs 50 degrees cooler about 140 F. I think I,ll get a bigger cooler to lower 110 f and a by-pass for cooler weather.  cooler is 4 row 10" long x 3" wide. | ||

You don't want her running too cool. Nice fab work while recycling parts! | ||
| Spiderman |
That is a HUGE cooler for your bike  Get a thermostat or you will get some damage going on... | ||

140F WOW. Mine runs around 200 with a billet finned oil filter. Where are you measuring the oil temp? My readings come from the tank's dipstick. (Message edited by pkforbes87 on July 01, 2009) | ||

I've never found a reason for an oil cooler in Florida. I wish I had one a few times sitting in traffic that's unavoidable in Daytona or the Keys, that's it. 140 isn't even close to operating temp is it? | ||

Laser light hand held Thermostat.Inside oil tank while testing and is accurate! had it a year use on many things.Will install dash elec therm tonight.My hemeriods love that cooler!!!!That plastic-oil-bag is crap compared to S2 aluminum oil tank!!!!!  110,115 deg I,m shooting for I,ve ben reserching it on bad-web for a long time (Message edited by ebutch on July 01, 2009) | ||

Aren't you concerned about water build-up in your oil tank if you don't let the oil get hot enough to boil it off? rt | ||
| Ebutch |
Ya.Water in oil can be seen milky color.110 degrees will evap water in summer.a Florida Bad-Weber had his Buell set-up that way.I pile a lot of miles going no-where!  | ||
| Pkforbes87 |
110.. the past couple of weeks I think I could get my oil that hot just by moving the bike outside into the sun. | ||
| Ebutch |
My S2T(122,500 miles strong un-rebuilt miles)runs 110 F.  | ||
| Pkforbes87 |
I just don't get it. Everything I've read says that the head temp sensor should be reading in the neighborhood of 300.. how can those areas get so hot but the oil that cools those heads is only 110? I realize it's going to cool down by the time it gets back to the tank, but damn.. | ||
| Blue_pipe |
Phil were did you get your temp dip stick I've seen the harley version it looks longer than what I got in there. | ||

"Everything I've read says that the head temp sensor should be reading in the neighborhood of 300.. how can those areas get so hot but the oil that cools those heads is only 110?" That's the return temp to the tank after it passes through the cooler. The tubers are not oil cooled. XB engines squirt oil at the piston, and the oil absorbs heat. Tubers do not, and consequently do not put as much heat into the oil. It isn't an accident that XBs have oil coolers stock and tubers do not. I think 110 is too cool for the oil. I would use a 180 degree thermostat inline with the cooler. In fact, I do. | ||
| Ducxl |
WOW..With such COOL running temperatures,i wonder what bikes equipped with electronic choke enrichening devices *think* of that. | ||
| Hootowl |
I don't think anyone has mentioned engine temperatures, just oil temperatures after the oil is returned to the tank after passing through the cooler. But like I said, 110 is not warm enough IMHO. | ||
| Ebutch |
My mistake! 190 F.Will ride S2T tonight have Harley dip-stick gauge in it will check temp.Really think I was right on that one.Cann,t tolerate heat through seat anymore on S3.  | ||
| Hootowl |
190 sounds better  | ||
| Pkforbes87 |
Blue_pipe.. got my dipstick from a place called KC international. http://kcint.zoovy.com/ It is longer than the stock tuber dipstick but I just used a razor to scratch high and low lines in the same locations as the stock dipstick. Don't try squeezing the dipstick or you'll pinch the wire that moves the temp needle. I put my first one in an electric drill and chucked down on it so that I could "machine" marks into it.. yeah that didn't go too well. Luckily the dipsticks are less than $20 so my lesson was learned without too much expense. 190 sounds a lot more reasonable for oil tank temps. Any idea how much capacity the cooler and lines add? I would assume that extra oil capacity adds to cooling efficiency. | ||

S2T whent for ride 20 miles,Harley oil therm.Head tem  p 292 F. oil 146 F. | ||
| Ebutch |
Will Run S3 Thurs post results.Head and oil temps | ||
| Buellistic |
BUELLers: In order for your engine to operate correctly, the engine oil should run at a temperature of 160 degrees or more ... You must remember the your oil also acts as coolant for your engine ... "i" have run a oil temp. gauge for years now ... How about a debate on this from everyone ... MAY THE LONG LASTING BUELL BE WITH YOU !!! | ||

Today 40 miles,75F. 15 miles,head 336 F,oil 136 F.Also installed elec oil temp senser runs 6 degrees Lower than laser sens,pick-up inline before cooler.30 miles,head338F ,oil 132 F.40 miles,head 341 F,oil 132F.Head temp meas. at just rear spark-plug of rear cylinder.Runs Great,very strong.but maybe don,t need cooler or maybe bypass.also thermostat. | ||
| Natexlh1000 |
That's a riot instead of hooking up a bypass hose for colder weather, you could cover it up like a trucker!  | ||
| Ebutch |
First of all:Thanks for warnings!Took off home brew cooler.75 F outside here today.Went for ride,15 miles oil 168F,Head 341F.50 miles,oil 159F,head 309F.100 miles oil 164F,head 325F.Those are better #s.Thanks again for warnings! | ||

I have never been a fan of add on oil coolers, just too many lines to chafe and connections to fail. The factory ones tend to have much better lines and mounting. Most importantly, if a bike really needed a cooler, the factory would have installed one. The XB is different than a Tuber, the frame covers up to much of the engine to allow the air cooled engine to get at the air and I am sure that is why it got the cooler and the fan. | ||

Whether a machine has an OEM cooler or not is moot. If you ride outside the "designed ambient temps", you or your machine must adapt. Once you know optimum operating temps for your machine, do what it takes to make it run there. An oil cooler in Manitoba is probably a bad idea An oil cooler in Barstow, CA is probably a GOOD idea. | ||
| Loki |
So which Tuber came with an oil cooler installed? | ||
| Skntpig |
None. He was saying that an XB came with them. | ||
| Loki |
Trick question of a sorts. Yes, there was one(at least) tube frame(model) that came stock with an oil cooler. | ||
| Loki |
A properly sized oil cooler can be beneficial to a tube frame bike. The key is make sure the oil is hot enuff to burn off water and such. From my personal experience and perspective. I ran a Jagg on my S1. The only reason I took it off was the switch to the XB heads and cylinders. The extra cooling fin area(+25%) negated any need for it. I also had a temp indicator reading the oil at the outlet. With a bypass switch for the cooler weather. Yet I may consider putting it back into the system. I need to see how the hot weather and big bore kit interact. | ||
| Phelan |
I picked one up from an XB, along with lines and pump, that I'll be installing. I can always put a rag or something over it in the winter. | ||

Blue Pipe, check the Sportster thermo dipsticks. The one I have is longer but has lines in it that match up with my stock locations. Probably just a coincidence but I've had it several years now. |
