Working on the cafe' project and trying to get the logistics done on the engine. Since it is going to be a little sportier with the engine I am planning on having Scott modify the cases while they are apart and add the ports for an oil cooler. Since it is not a SFC frame what cooler would be best for use with the mounting available on a standard SF frame? Any special brackets need to be welded onto the frame?

Hi Clay - almost any type would do - bracketry will need to be done for any type - I bought this one on E-bay recently for my 860 project - mainly because I got it cheap and fittings are can be aimed in any direction. - Regards - Phil

Thanks Phil. Trying to figure out what would work best is what has me baffled. Do these oil coolers have thermostats, or maybe a better question is a thermostat really needed? For a race machine I would think not, but for a street/track machine I would think yes (except that they are air cooled anyway so the extra cooling would be good). And since I am going to use a fairing from Boba the size of the cooler comes into play also. I'll start looking and see what I can find.

Only ever used a piece of thin plate or cardboard if day was a bit chilly - any bike size should do - if it's staying as a 750cc and has a decent oil pump - not too sure an oil cooler is a must. - Regards - Phil
 
You cannot run a thermostat on an oil cooler, means you would have no oil flow to the top end when the engine was cold, not a good idea at all

 
Doesn't a thermostat need a bypass for the oil to the head when it isn't allowing oil through the cooler?
I vaguely recall such system way back in the day when aftermarket oil coolers were more common due to lack of standard fitment.
 
Thermostats are still the way we do it with aircraft oil coolers which use a bypass when cold. Have no idea what a bike one would do so that's why I am here asking the experts  :D

Ya'll have forgotten more than I'll ever learn so I need all the help I can get.

As for the need I'm not sure either but if I spend a good amount of time on a track I figure it wouldn't be a bad idea. Plus our summers are a bit warm and humid with the afternoon norm around 95-97 F.

I had the Norman Hyde equivalent of one of these fitted to my T160

It sat above the cylinder head immediately behind the cooler (oil pipes are routed over the top of the engine on the Triumph/BSA triples. Whilst undertaking a rebore some years ago I noticed the inside of the oil cooler was dry and lightly rusty so I took the thermostat apart to check it. Dropped into a pan of hot water it worked just fine. After 3-4 years of use (including a trip to Hasselt in Belgium) the oil hadn't reached the thermo's operating temperature once... I never really flogged it though, with high Bonnie 'bars :o I couldn't hang on above 80... :-X

SF frames don't have cooler brackets of course.
There were nice coolers on Zane Laverdas, plenty going for scrap prices on ebay.
