my bike came with the stock HD oil cooler, even in 100 degree temps and sitting for a while i wont get much over 160 - 180 degrees. oh yeah, im here in arizona where temps start out in the morning at 100 + and will hit 120 degrees.
Where and how are you measuring engine temps? 160-180 F are really low temps, especially in 100+ F weather.
You can lower your temps around 10 degrees using an oil cooler. Basically useless and ugly to look at, not to mention having the need for external oil lines that could be damaged easily. You can gain almost 150 degrees of protection just by using a full SYN oil. There will never be a need to use an oil cooler, even in the hottest days in stand still traffic temps if you use a full SYN..
yup I run Amsoil on everything. Bike, trucks hell even use the small engine Amsoil in my lawn mowers
My fan kit will keep your motor cool in traffic. The fans are water and dust proof and move alot of air. Right now I'm having a Sturgis sale , 15% off.

I wonder if oil coolers have improved since this thread was started nine years ago? For completeness sake, I have the Wimmer twin tube oil cooler.
I use synthetic and I hit 250 and over all the time and I rarely ride in traffic.
Most oils start thermal break down at 280*. If your consistently running 250* and above I would seriously consider looking at your tune.. might be a bit lean or even to much timing... Also a 10 row Jagg will lower oil temps 35* (moving)...
+1 on UltraCool.
From what I can tell it keeps my oil around 220-230 in the worst case.
IMO- the time an oil cooler is most beneficial is in stop and go traffic.
So if you have one without cooling fans I'm not sure the oil cooler is that effective at least when you're not moving that much.
