What oil?

[belfastguzzi]

OK , I'll bite. Whats the ' rest of the story?'

Ok, recap:

so, ZX 6R with 20,000 miles

run the engine at 8,000 rpm for 30 minutes to sort of warm it up

pipes glow... red hot

coolant boils and overflows - all of it

radiator fan switches off as no coolant to heat the switch

continue to run engine at high revs for another half hour

no apparent problems

- could wear be increasing, oil burning or carbonising -- seized bearings or pistons????

 

the manual says 3,5 litres capacity

is all that oil really needed?

 

Drain oil, boiling oil melts plastic tank as explained before.

 

Part 2:

put in ONE litre of oil (funny, they don't seem to debate what sort would be best)

oil boils immediately, but carry on anyway

start engine, tape throttle fully open.

 

Shortly there's a bit of a hiccup as backfires start. The rev limiter is cutting the spark so that petrol is exploding in the exhaust.

Big flames, small holes appear, big holes appear, big noise, fire extinguishers appear.

Leave the building, coughing.

 

Conclusion of story:

Come back next day when things have cooled

put in oil

start the engine

it runs smoothly

Hooray. The bike won.

 

Go on - try it for yourself.
