I have the same LBZ and have overheating problems too.

I suspected a plugged rad, so I had it removed and at that time had the crud blown / hosed out of the rest of the stuff in front of the rad. A multitude of bugs and other debris came out.

I didn't have the bucks for a new rad, so I put in a known good used one for now.

Everything is clean in there but my LBZ still gets dangerously hot hauling my TT up a long grade.

My next fix is a brand new rad to see if that helps. Can't believe the money they charge for stuff like this.


Just a thought, have you replaced the thermostats? One or both may be failing.

Yes, and the water pump too.
