Hi all,
This forum has been great to me before so I'll try again:
I recently bought an '89 GPX600R and have ironed out all the bugs other than that it seems to be constantly running too warm.
Firstly I replaced a dodgy thermostat which helped to a degree.
Next I replaced a non-functioning radiator fan switch which was heavily corroded/fouled.
The temperature seems good and stable on long, open rides but the stop/start stuff round the city is when it really warms up and starts leaking coolant out of the overflow pipe.
My next guess is the radiator needs a good flushing out (I hear there is some chemical product that does this).
Any ideas sure would be appreciated!
Cheers,
Guy
