So this damn bike keeps overheating. Ive changed the fan switch and the thermostat (pain in the &ss) and its still running super hot. The coolant in the hose between the waterpump and the radiator iunder a lot of pressure. the only thing I can think of is that the pump is bad. Any Ideas?

I doubt the pump is bad...there would be other signs first. It's possible you've blown the head gasket..which is HIGHLY likely if the bike was overheated due to the failed 'Mosta' [ thermo] switch. Another possibility is that the system needs to be 'bled', a process where all trapped air is evacuted from the cooling system by means of 'bleed' screws provided. Consult your service manual for the proper procedure and sequence for bleeding. Good luck. ..and feel free to pm me for other suggestions or help.
