May Have Resolved My Running Hot Problem

[TheJimer]

I think I may have resolved my “Running Hot Problem”!

On 105 degree days (indicated on Outside Air Temp (OAT) gauge) I was running a 298 degrees oil temp.

In addition to the previously installed Vance & Hines Oval Slip-ons and Stage 1 AC; today I installed a:
 Power Commander V by Moto Fuel w/Auto Tune (richer mixture)
 Jagg FLH 10 Row ’09 Low Mount Oil Cooler-P/N2400 (claims to be 40% cooler than the stock 6 row)
 Jagg Adapter w/Built-in Thermostat-P/N4700
 Big Sky Oil Cooler Fan Kit
 Red Line 20W60 Synthetic Oil

I have not had a chance to do a long duration of Interstate State Hwy. speeds since doing the Mod’s but I did do 40 miles of 20-40 MPH of city driving with an OAT of 105 degrees and the oil temp gauge indicated a high of 242 degrees.

This is a little higher than the 230 degrees Harley calls normal but it is a heck of a lot lower than the 298 degrees I previously recorded and the engine no longer pings or generates “leg burn” heat! Additionally, the bike seems to run stronger.

I sincerely believe that there is NO ONE single solution to the running hot problem, merely a combination of several items and I think/hope that I have found the right combination!

Yes Jim that combo should do it. Make sure you always keep synthetic Oil in it. Regular oil starts breaking down at 250 degrees.

I run V & H true duals, Oil Cooler and the fan with the synthetic oil. Outside temps of 95 and I run about 210 on the temp gauge. I only use the fan when I expect slow running. You have to remember to start it before you heat up.

Keep us updated on the Power commander with Auto Tune. I tried the Thunder Max with Auto Tune and was not happy. For some reason my Thunder Max keep losing the max throttle position. I would roll on the throttle and it would fall on it's face at anything above 80% application. I reprogrammed all was okay for a couple of weeks and then the same thing happened. Went back to my programmable Power Commander. Very happy with it.
