Got my ST back yesterday.
A bit more minor work required when parts arrive. (Rear wheel seals and bearings)
Two radiator hoses which vanish somewhere underneath the carbys to the motor.
One of had a 2” split, which instantly and un-noticed, drained the radiator rapidly.
As there was no coolant, sensors for the temp gauge and radiator fan did not operate
so I had no warning of overheating.
Standing at lights with no airflow, motor overheated, and on leaving the lights, engine
heat transfer affected the clutch slave cylinder seals, and the clutch plate delaminated.
Here’s the kicker..... the hose that blew was a YAMAHA branded part, obviously fitted by the previous owner.
Hose was considerably softer, and had been forced to fit the Honda engine,
by over- tensioning the hose clamps. (larger diameter hose than the fittings)
Replaced both hoses, replaced cush drive rubbers, clutch basket and plate, oil changed, Changed rear disc and pads.
carbys adjusted, replaced temp gauge sensor as it was non-operative, filled with new coolant
(temp gauge now operates, as does the fan temp sensor) New plugs fitted, general tune up.
Runs smooth and sweet. Did a run to Melbourne and back last night (750Km) arrived home again at 4 am this morning.
Rained most of the way and was almost freezing at Ballarat after midnight on the way home.
Pleased to be mobile again.
