It amazes me how much dirt gets in the hiding spots that you can’t get to. I decided to put a rad relocate on and I washed the quad 3 times to get all the dirt and mud off from the trails I have been on. I only have 15 hrs on the bike and 65 miles. I don’t do the mudding either. The outside and under neath you could eat off until I removed the plastics in the front and seen all the dirt that was missed.
I took out the radiator and set ion top of a 5 gallon bucket to clean. I had about 1/4 inch of dirt left in the bottom after I poured the water out. I spent several hours detailing underneath the plastics. It cleaned up well.
