Not leaking yet? ...
An old trick for the radiator hose ... An LH/LX Torana heater hose is almost perfect as a substitute when the seals fail at the steering head bearings.
It's got a 90deg bend at one end that is a perfect fit to keep the radiator on it's original mounts.
Yeah I had one and had the problem way back then.
Funny innit ... I sold my YZ125c for $500 bucks to pay $800 for the H, then to sell it later for $750 to buy a KX250D1 for $1200....
My how times have changed ...
