I bought a used 98 in August and after a couple rides I started looking around and confirmed that they all run HOT....like burn your legs hot.
I also swapped out the stock cooler (damaged) for an automotive transmission cooler...likely the same thing you've got.
If there's room (and there is lots on mine) I'd add a 2nd one.
The one I have has a lot more surface area, but isn't nearly as thick as the factory cooler, so all told, it likely had a little less cooling surface than the stock one I took out.
If your fan is running, I wouldn't say an exhaust leak would be a factor at all, as far as it leaking on or near the cooler....
