After a long weekend of some very dusty trails and 85-90 degree temps we had alot of issues with getting hot (especially the popos that we were riding with). I do have to admit my temp light came on 1 time and when i looked down sure enough my radiator was plugged up.

I know there’s a lot of ideas on how to clean the radiator out on the trail; squirt gun, bilge pump, water bottle, running it through the creek if available……
What have you guys made or acquired that has been the most effective way to clean your radiator out on the side of the trail?
