1978 kz650 Oil pressure warning

MOT booked for tomorrow so took the bike for it's first run to clear the
cobwebs after a long standing. After about six or so miles the oil pressure
warning light lit up and stayed on. Engine sounded fine, no additional
vibrations and continued to run smoothly even at idle. Is this as
disasterous as it first appears or is it simply a buggered oil pressure
warning indicator? Is there a way of checking this out without major
surgery? Oil good quality and levels fine. Changed it at the weekend.

 

Have you left out (or put in the wrong order ) the spring and washers
related to the oil filter? Just seems coincidental that this has
happened after an oil change?

Its been a long time since I changed a z650 filter but I seem to recall
a spring and washer to keep the filter pressed inside the sump.

For what they cost I'd be tempted to try another oil pressure switch.

The oil pressure on the z650 is higher than the z900/z1000 range cos the
650 is plain bearing crank and the bigger engines are roller bearing
cranks.

Or the insulation to the wire chafes through, allowing the wire to
touch earth and the light comes on. Very common on older bikes,
especially as the wire drifts from its mountings and vibrates or gets
too close to hot bits and gets brittle.

 

Spot on Pip. Wrapped the connector with insulating tape and all hunky dory
once again. Thanks for the advice. By the way, bike sailed through the MOT
so all set for some good biking.

 

Fucking sorted, mate.

The old sticky tape bodge, eh? The old ones are the best ;-)

The roads are dry at the moment, too ...

 

Excellent. You give the pertinent advice, I stand around mumbling and
get the credit. I can live with that if you can ;-)
