450wr one hot rad

3 posts in this topic

Hey everyone. I'm having issues with my 2006 wr450 getting hot. Im currently running the blue ice and I still have boil over while trail riding, noticed a slight positive difference. Mostly we ride 3000-7000ft single track mountain trail riding, at 70-80 deg dessert weather. I can stay between 1-2 often 3rd. But usually 20 mins into a ride I can hear my rad starting to boil. On descents I've tried to keep it in neutral but stills boils over ( believe because the pump doesn't run while in neutral)

Wondering if there's a clog in the line? Any thoughts?

1.  boil over is a factor of pressure. If you raise the pressure, it will take longer to boil over. Go with a higher psi cap, like 1.4

2.  Jetting: if you your jetting is anywhere near stock, it will always overheat. You MUST uncork and re-jet that motor. Thousands of posts on the subject. Read the FAQ section

3.  The pump is always running.

4.  If you are running the stock exhaust , the engine heat is being trapped in the exhaust, raising the heat of the motor
