I'm still curious how an oil cooler will help. The clutches heat up from friction from the slipping. So now are they just going to slip but remain cooler? Sounds like they need to fix the clutch slipping issues that some machines have!
The clutch disc material is attached with a binder of some sort. Hypothetically if the oil gets hot enough to degrade or break down the binder, the clutches could fail.
I don't have a clue what the binder is or what point it would degrade. But, keeping the oil cooler might be beneficial.
The clutch slips a little bit all the time when the RPMs of the wheels and the crank don't match (like speeding up or slowing down and starting/shifting). If the heat isn't getting out of the oil in a timely fashion, it might be building up to the point the clutch wear accelerates way beyond normal.
That might also explain why you guys that run Bull Run a lot don't have problems like some others do. Since you are in and out of water a bunch your overall average oil temps may be lower than those that are relying on just the radiator dump the waste heat out of the whole system.
That is why I am very interested to see what Honda's fix is. Heat or clamping force or electrical or a combination of all of them or none of them.
