DIO Racing Radiator- Re-build. 1

I am going to totally clean and rebuild my water cooling system for m HIGH PERFORMANCE DIO ENGINE. Either I have too much pressure at the pump or a clog or something. The trick is to go thru ever part of the radiator cooling system and narrow it all down. More videos will show intricate working to get this bike up and Rolling at 90mph by Spring. It is good to be old and good to like Honda Racing Mopeds... ROCK ON!!!!!
