Elec system effect oil temp?

[Nessism]

Some more AA for Jim's benefit...

Temperature: 83F

Ran 30 miles on my 1000S with a FH-009 shunt style R/R and checked temp. Then ran 30 miles back after switching to the SH-775. Checked gauge calibration by putting a thermocouple down into the oil. Judge for yourself.

The oil temp was in the 290F range when blasting on the freeway at 80 mph. There was a fair bit of traffic so the air temp may have been hotter than mentioned above. When slowing down the temp dropped quickly. The final temp (photos) were taken after getting off the freeway and then driving about 1/2 mile.

Bottom line: the R/R is the least of the bikes problems when it comes to heat. A large GS running at fast freeway speed runs HOT. I run synthetic oil but I'd run an oil cooler as well if this was my daily driver. Good news is the bike didn't care about the temp; bike ran flawlessly and didn't show any stress due to heat. Gotta love the toughness of the GS engines.


Claim: stator heat increase oil temperature...

Ed, I believe your pictures although not your analysis. It appears that your bike tends to run cooler or cool down quicker that the 1100's. Why, air flow probably. And again this effect only becomes pronounced for 1166 cc. Although at very high temps on a stock 1075 there is also a change noticeable. An and 1100 generally doesn't get hot from running fast, it tends to get hot running slow. And 80mph is not really blasting unless you are in 4th or perhaps 3rd gear.

What I can't understand however is how and why you can be so adamant that this proves that 16V BB doesn't see temperature drops when there are multiple people that say they have such experience? No need to answer, the question rhetorical.

Jim,

The discussion focus is whether or not a stator that's receiving returned (shunted) current from the R/R contributes to oil temperature. The type of engine and/or the state of tune of the engine is immaterial. My experiment clearly shows that shunt style R/R's do NOT increase oil temperature. It doesn't matter if my engine was a 1300cc monster or stock, the results would be the same. Stator heat does not increase oil temp.

BTW, hope you forgive me for not taking a photo of the gauge at 80 mph. Would have loved to, but decided against it. The oil temp maxed out at the exact same level regardless of whether the shunt or series R/R was installed.

There are two heat sources inside the engine: Combustion heat AND stator heat.

All part of a though engineering analysis.

Yes, of course, friction. To be honest, I wouldn't have even included that business about "stator heat", but was trying to be fair to Jim and keep an open mind.

OK after I get back from dinner (and a couple of refreshments) I am going to do the only type officially sanctioned analysis at GSR.
