After finding the highest oil temperature my bike sustained without a front fender, I decided today to test a drilled fender. I drilled as many holes as I could, while still trying to maintain the structural integrity of the fender.
![]() After mounting this fender, I actually removed it, and drilled more holes on the outside edges. ![]() If I didn't fully understand before, I certainly understand now. Maximum airflow is the key to keeping oil temperatures lowest. ![]() ![]() ![]() I decided this was my final ride with this drilled front fender. ![]() ![]() After I arrived home, I cut a large square out of the fender, and installed some 1/4-inch, galvanized hardware cloth. I'll post a photograph of the modified fender later. The next time weather permits, I am going to make another freeway run, and this time I expect the high oil temperature will be much closer to 255 degrees than 279 degrees. ![]() Spud ![]()

Is the aluminum I sent too small? I will take that roll with to Kansas.

Is there some way to make some air scoops to direct more air over the cooler?

Here's a photograph of the modified fender installed on my XR650L.

I got a little wet at one point, but I still made several, freeway test runs of my oil cooler today. My latest fender modification was successful. Riding the same stretch of freeway that yielded a high oil temperature of 279 degrees yesterday, my high oil temperature was 248 degrees today.
![]() I also rode the same section of freeway that yielded a high oil temperature of 255 degrees without my front fender mounted. Today, with my modified fender mounted, I reached a high oil temperature of 253 degrees. Riding back home along this same stretch of freeway, I encountered very strong headwinds that kept my speed at 75 mph while riding wide-open-throttle. My high oil temperature under these conditions was 235 degrees. This oil cooler installation works very well. ![]() ![]() Another forum member promised to loan me his XRs Only temperature gauge next week. After riding a few miles with his oil dipstick thermometer, I will report the difference in temperature between my temperature probe located near the engine, and the oil dipstick thermometer located in the oil reservoir. ![]() Spud ![]()

Your TTO seems to be paying for itself already. I'm interested in the comparison.

Sounds like you've optimized it, Spud.

Are you planning on a fan now?

I don't think I need a fan, Weld.

What was the original application of the cooler?

I'm now thinking of getting a TTO for my oil or my coolant on the YZ. Although I've never heard of anyone doing this on the TT forums...
Looks like cheap insurance that's for sure. I WISH I had a cooler and gauge on my little 250 back in San Francisco. :roll:
