What is the proper way too bleed the coolant system on and nsr 125rk??? Also how does the thermosensor function (just the bit that links to the temp gauge)??? Is it by pressure or a temp thing??
Many thanks

if its that same as my Tzr there is a bleed screw on the top the thermostat housing on top of the engine, where the hose comes from that goes to the top of the radiator, anyway, from empty u slowy fill the radiator 2 minimize the air getting in whilst having the bleed screw out, eventuly the water will start pouring out make sure all the bubble are gone.
now run the bike till its all warmed up then just top it up till full..
should work a treat BUT i cant get mine to get up 2 temp?????
Any one know stuff about the impeller drive?

Hope this helps
