I have an S&S T124 installed in my 01' Dyna, since 07'. The hottest Ive recorded was in Sturgis in 08', 99degrees outside, stuck in traffic for 45 minutes. Oil temp climbed to 215 degrees. Out on the highway is same temps it stayed around 195. At home it has never reached 190 (southern Ontario, Canada).
Harley's always looking for an excuse, usually blames the Emissions, but it certainly doesn't have to be that way.
If they cared (HD) about anything other than stealing your money, they could easily design an engine around liquid cooling or oil cooling like Polaris with looks not really different than what you see now. Even installing a big oil cooler as stock would really help, but HD has chosen to work the percentages of failure instead of a real design that works.
I love my 01 Dyna, I even liked it stock, then with 93hp/98t, then with a supercharger (Magnacharger) at 125hp/125t and now with the 124. None of these ever run anywhere near as hot as these new bikes. The 95" Supercharged motor did reach 230 degrees one day at 160 mph on a 95 degree day, but normally run at 200.
I won't be considering a new Harley anytime soon, not until they solve these dependabilty issues. FWIW twinotter
