Is the oil cooler flow thermostatically controlled? I have not found anything to indicate that it is. The past few days of riding in sub-40f morning temperatures has me wondering. Mark in Arizona | ||

I'm afraid not. Oil goes from the oil pump through the external steel lines to the oil cooler and back to the oil filter mount. Think transmission cooler on a car. Other BWB'ers stuff a shop rag into the scoop or tape over the front. | ||

Thanks. I did not see anything external that looked probable. My BMW R100 has a very obvious thermostatic bypass at the oil filter cover. Since the Uly's cooler is standard equipment, I wondered if there might have been an internal bypass. Mark in Arizona | ||

To my knowledge, the only things you'll find there are an oil pressure switch for the idiot light and a ball & spring type oil pressure regulator. For something better than rags or tape, you could hook up one of these http://perma-cool.com/Catalog/Cat_page14.html below or beside it. If your Uly doesn't have CA emissions, you could put it where the charcoal canister goes. The hoses and fittings should be fairly easy to find at any auto parts store. | ||

Thanks for the info. That looks quite interesting. (Message edited by Mark_weiss on December 22, 2008) | ||

Living in Switzerland and riding all year (Unlike all the Harley pussies around here) bringing oil up to temperature quickly has been on my mind for a while but I am wondering just how critical it is or are we just over egging the custard here? | ||

I am wondering just how critical it is I doubt it is that critical. Air cooled engines have to be fairly tolerant of temperature fluctuation. Despite that, I wonder about my oil temps too. I ride a lot in the cold, and I suspect the bike was not optimized for cool weather. The first step would should probably be to get one of those oil temp dipsticks and see what temp the oil actually runs in the winter. That will answer a lot of questions. | ||

My main oil temp concern is management of moisture. If the oil stays too cool, condensation will not be boiled out of the system. Even here in Arizona, that can be a concern Mark in Arizona | ||

I checked my oil the other day, and the stick was covered in a splooge similar to that i find in my catch can. I have been making 30 minute highway rides, but I guess thats not enough when the bike has a layer of ice on it. | ||

There are inline thermostats available. I put one on my tuber when I added an oil cooler. | ||

You could always try wrapping or covering the oil cooler to eliminate airflow during the colder months. |
