Do oil coolers realy make much of a difference?

[thefox]

I have a 1981 Yamaha Seca 750 road bike (air cooled) with 10,000 miles. The U.S. model did not come with an oil cooler but the Canadian models did. So should I get an oil cooler from a Canadian model and put it on mine? Would it realy make much of a difference?

Thanks, Andrew

Oil coolers do make a lot of difference. They can reduce the temperature quite a bit.

Probably cool that oil 60 degrees F. On harley's it cools them that much, even a small one.
