Engine temp for 96" 07 & up
Wondering what the average temp people are getting for the stock 96". I have an 07 with oil cooler and getting readings as high as 230. I was told by HD that the later engines run hotter and this is the norm.

Maybe this will help you out
man i hear ya. check out nightriders.com they explain pretty much what the issue is. hd has the fuel air ratio set @ 14.8 to 1 which is super lean causing the bike to run hotter. reason has something to do with cleaner emmisions.

Late engines run hotter cause the tuning sets the A/F ratio almost everywhere on the map at 14.6. This is the closed loop. The EPA requirements force this. Nothing HD can do except desigh good parts. There are a few areas where this is wanting. Cilenders for 110 one area.
These things are adjustable using various methods. If I didn't have so much in SERT I would look at TTS Mastertune or Zippers Thundermax. These are the Cadilaces of tuners but pricy.
After much work, my oil temp on a 85 degree day is about 200 deg.F with fairly hard ridding. And plugs look just right. No soot at the exhaust.

230 on the 96" is not bad at all. The routinely run 250 plus and 280 or more is not uncommon in stop and go conditions and high ambient air temps.
With a good tune it is entirely possible to have an engine that will normally run 205 - 215 , hotter in stop and go but not anywhere near the temps you will see on a stock bike.
Tune is the key - proper ignition timing and air/fuel ratios.

All the newer HD's should have oil coolers. A big generous cooler. At a certain point function has to be above form.
As many as needed or as big as needed to get oil temp 195 on a hot day. Especially the baggers.

You can thank the EPA for all this. With stricted emmisions, Harley sets the A/F in cruising range a 14:6, way to lean IMO but it is what it is. Harley did answer by putting parade mode in hte ECU, which means that when the bike is hot and at lower RPM's the ECU will shut the spark off to the rear cylinder. Works OK but the bike still runs hot. Harley's answer for the '09 touring bikes was to run the rear exhaust under the frame rail for the left side discharge. Keeping it away from your left leg. You CAN change your air/fuel ratio with a Super Tuner. WHen I dyno tune I usually turn the parade mode off, calibrate the bike at 13.2 air/fuel and set the air/fuel to 14.2 for the cruising RPM's and thrpttle position and 13.2 - 13.6 air/fuel for the 80 and 100 percent throttle positions.

I think you misunderstood my post - I dont at all like a bike that is running 250+, it is too hot and due to lean settings from the factory. 230 is not bad, and lower than that by 10-15 degrees is good.
