Billet engine cooler, do they work?

It doesn't really matter at a standstill... without air flowing through the radiator and/or cooling fins, your machine won't adequately cool anyway. It'll just keep getting hotter and hotter (eventually overheating). ANyone will tell you it's a good idea to shut off the engine if you just plan on it sitting for awhile.

If you cannot get the machine to hold a consitent temperature once she warms up, your test won't come out well because she'll already be hotter the next time around after being run for awhile. Place a fan (or a couple) to blow on the radiator and/or cooling fins to keep the temps down (and at a consistent level), and better simulate riding conditions. You'll get better test results that way. OR you can let it cool COMPLETELY (down to room temp) when you install the fins. And measure the amount it time it takes it to warm up to a specific temperature both times.

Since we're only talking a couple degrees difference, you'll have to make sure the test conditions are EXACTLY the same, when you test it BOTH times! You have to control the conditions yourself. No wind, excpet what YOU provide by the fans (since windspeed can change constantly), and also the same ambient temperature. If you have to test 2 separate days, so you can let it cool completely make sure you begin the test at the same ambient temperature as the day before. To test such a "small" difference, every little bit will count!
