oil cooler help

The differances between a stock cover and a 1150 cover

The 1150 cooler lets some oil pass through the engine as not to over cool the oil.

Well since you're not shunting all that extra current though the stator generating extra heat it removes a heat generating source from the equation. Someone on here did teh work and gathered the numbers and found that going to the series R/R dropped oil temps by as much or more than adding an oil cooler.

I don't believe it. I did my own test, back to back over 30 miles of mixed riding, and saw no drop in oil temp. You are free to believe what you want though.

Agree. I haven't tried this by myself but even in theory the R/R can't make any significant change to oil temp. Based on generator output power maximum amount of heat that the stator can generate is around 300W. And that's in case where all generator power is burnt to heat in stator windings, nothing going to charging. So in reality difference between series R/R and traditional one is much smaller. 100W could be at right ballpark. For comparison total amount of heat generated by the engine at normal cruising speed is probably something like 10kW so no matter what the stator generates it won't change temperature balance much.
