Try Engine Ice instead of the regular anti freeze. It seems to make my 99 run cooler. Slow going single track can cause overheating. Our bikes are not as bad as the DRZ's.

I've also had lots of heating problems with my 400 on slow trails. I would suggest going to a 1.6 radiator cap and running 80 to 100% anti-freeze. This seemed to work well on my bike. Goodluck, Eric

80-100% anti-freeze?? That would simply made it run hotter yet. Glycerol is NOT a super good heat conductor. For optimum cooling, you actually want 100% PURE distilled water. The coolant/anti-freeze just helps keep corrosion down, as is as anti-corrosive additives.
I run probably 90-95% distlled water, with a splash of Prestone Aluminum coolant/anti-freeze, and the reccommended levels of Water Wetter in my 520. I putz quite a bit waiting for people, and no heat problems whatsoever....this is an SX model, with no fan.

Chris, the high percentage of anti-freeze does make the bike run slightly hotter but anti-freeze boils at a higher temperature than water so you don't get a boiling problem. I have tried everything from 100% distilled water with water wetter and found poor results. I'm glad that combo works on your 520 because I plan on getting one. Also, your 520 radiators are substantially larger than a Yamaha's.

interesting blue...just wondering i it still gets hotter than normal, just not showing it now.
if these have any batteries on them...or perhaps off of lighting coil....has anyone contemplated rigging a fan? just add a switch, relay it from the lighting coil or battery, and there you go. think that could work?
