OVER HEATING

Last weekend while riding my 04 450 FE would not stop overheating even
while running fairly flat 2nd/ 3rd gear wich I thought where not normal
after the boiling had stopped I carefully open the radiator cap only to get a hiss bad rad cap I thought well back home I pressure tested the radiator with rad cap installed in radiator pressure released at 25 psi and
opening the rad cap would be loud hiss too make long story short what I
found was that overflow hose nipple on radiator (wich is plastic) had been pushed in slightly probably by installing overflow hose that made the rad cap not seal very good it would release at 12psi BINGO problem solved
the fix is easy simply counter hold nipple with screwdriver while you push on overflow hose and be sure that is hose is on all the way to the aluminium that way nipple go inwards and interfere with rad cap I would
think that this is common problem

conclusive and easily duplicated

Well nothing like real test ride in step mountains and 95`F (32`C) not a
drop lost it ran cool other brands where not as fortunate I am thrilled to
have finally solved sometimes overheating and other times OK
