I've read some of the cooler threads.Some were showing what looked to be nothing more than external oil filters.Are they a form of cooler?Couldn't find anything on making one, so has any of you made your own?I built my bike without thinking of running one so room to put one on now is at a premium.Can a cooler do its job properly if mounted under the engine?I increased the capacity of my oil tank by about 1/2 quart, its actually two separate tanks,a feed & return tank connected by lines.My thought on this was to keep the hotter retuning oil away from the oil feeding into the engine.Plus the fact I am running an external filter.Will I see significant cooling with this?

On my Bonneville I plumbed in one of small U-tube finned coolers as seen on refrigeration compressors sometimes. It nestles down low between the frame tubes. Can't say for certain that it helps but it doesn't hurt.

first check your oil temps. oil that is too cool is almost as bad as oil that is too hot. i don't know what you ride but 180-200 degrees is about right for most bikes.

That would have helped...The engine is out of a BSA Rocket3.Originally equipped with a cooler.Cannt recall if it had one when I stripped it.From what I hear & read this engine runs hot.

i repeat, put a temp guage on it to see if it NEEDS an oil cooler. it did come stock with one but you may not need one. oil coolers are a lot like big carbs,big cams and open pipes. 8 out of 10 times they cause more problems than they fix.
