Bike has been overheating in the normal narly spots, but when it does over heat I would loss a large portion of my radiator fluid. Ordered higher pressure cap. Also ordered exhaust header gasket thinking sucking air could be causing over heating, not in yet. Recent changes to bike that might influence overheating are new OEM piston and rings (was 478 big bore) IMS 3.2g fuel tank (does it block air flow?), Revloc auto clutch ( Is it heating oil and causing over heating?) OEM radiator cap 1.1 mb, new cap 2.0 mb. Will higher pressure cap cause problems? Pros, cons? Other possible reasons for overheating? To lean? Ride at 8k' - 12k'. I think I have a 152 main jet.
