You have to keep the bike moving and you stop to rest, even if it is just for a moment, shut it down. If this isn't the case your jetting might be a little on the lean side. I have ridden in outside temps of 117°F for a couple of hours without boiling the coolant.

I agree. I've only had my bike boil over once and it totally freaked me out. It was the only time where I let it sit idling for some 5 minutes after a gnarly hill climb in the rain while I waited for my girly to catch up. Now I always shut her down instead of letting it idle.

I installed a drz400s radiator fan. Not so much for the idling, which it can do indefinetly now, but I've noticed it restarts better when I stall in the trees. It also seems to run at more even temperatures, the coolent doesn't make the gurgling coffe pot sound any more either. Just keep in mind I haven't ridden it when it's been above 75F I've only had it two months and ridden it on six weekends.

You will need to check to see if you have the same amount of room behind the center tab of the right radiator shroud as my bike does. I have a 2004wr450 with devol radiator guards and gytr 3.4gal. tank. The fan only has enough room on the right side mounted flat to the devol guard brace using two of the three tabs. It only fits one way and that is if you move the fan motor to the inside of the the fan bracket, this requires a 5.5mm socket and a phillps head screw driver. I used two insulated stake on wire connectors to connect to the fan plug, a water resistant toggle switch, and a 3amp in line fuse. It needs a two amp fuse to start but actually draws 0.15amps when it's running. The whole thing took about an hour and a half. I did end up shaving off the center tab on the right shroud, the fan does not stick out but the tab did. I'll post a picture if I can figure out this URL thing.The suzuki p/n is 17800-29f00 and was about $180us. Anyway good luck!

Hurray I finally figured out how to show my pictures! So take a look and you'll see just how tight this fan fits. I put a white napkin behind it to show the clearence better. It's a got about 3/16 of an inch all the way around. www.imagestation.com

You should be able to see three pictures, two are close up and the top view 5spoke put up for me. As for how I found out how to see the pictures at imagestation.com, I just went to the website 5spoke used in his bio. I made an album and copied the url address.

I overheated on a deep woods ride where speeds were pretty slow for a little while going uphill. I'm going to try this waterless XF+ coolant from Zip-Ty. Has anyone else tried this stuff, and what were the results?
