That would mean it could reach 250F before boiling over.
A heavy duty cap would be 1.6 bar or 20 psi. == 264F
JB weld is fine up to 500, so no worries there.
+1 for the cleaning -- I suggest brake cleaner because its easy to get and does not leave a residue. - JB weld says acetone, lacquer thinner, and not alcohol.
remember to add atmospheric pressure when using the charts.

I have used JB weld on the cylinder head by the KIPS valveand have had no problems.

Under normal operating conditions a motocross cooling system runs about 130-150F. MX bikes don't use a thermostat so coolant temps can be all over the place, depending on many variables such as ambient temps, jetting, piston top end condition... and so on..
