Oil cooler

[CIP57_imp]

I think its a poor design. They should have at least let you drain the cooler with a primer to refill. Leaving a full quart (20%) of dirty oil in the system just does not make sense. Remember this oil runs through the tranny collecting a lot of metal and brakes down much quicker. They would have been much better served to make a water cooled radiator the same size if there going to put it there at all, this would have allowed fresh oil changes.

Doesn't it drain down by itself? Or does the check valve in the case stop that? Guess I'm going to have to look at the oil diagram in the service manual.

Ok the above was a stupid thing to say as the lines are at the top. I apologize.

Pop,

If I remember correctly (don't have my manual) the total capacity is 5.2 qts dry, this would leave over a qt in the system via oil cooler.

Honda Goldwing from 1974 was watercooled.

So not only is it big & ugly, you can't even drain it properly.
The only option for me, is to replace the oil cooler with one about half the size. I don't think this option would hurt reliability issues. So if the Aftermarket comes out with one for the CB, or a existing one used on another model might work also for me...........

Mmmm. Liquid cooled motorcycles have a very long history, dating back to the early 1900s. For example would you consider a liquid cooled motorcycle manufactured in, say, 1908 "Retro"? That's about as "Retro" as you can get

Hmmm... Guess I'm not that old, I consider bikes from the 60's and 70's "retro"

The Suzuki water buffalo was water cooled and came out in 1971.

Scot Flying Squirrel was a water cooled 2 stroke from 1909.

All true, but I don't think anyone can argue with the fact that the vast majority of production bikes were all air cooled in the 70's. It's just my opinion that was Honda's intent when they came out with the CB 1100.

For the record, I don't think the oil cooler's capacity is anywhere near a quart. Yes, you do leave some residual inside the engine between changes, but it's not worth losing sleep over.

search for a sportster oil filter





smaller, but not sure about attachment to the cb1100.

I wouldn't buy a used CB unless the stock oil cooler was in place.

Why not put a cover (protector) on it ? http://www.samurider.com/?p=13491

It would look like a small water cooled radiator.
