Change oil before or after ride?

[inlinefour]

Hot/cold? Has anyone just heard of plain old warm?

[eliot-ness]

I wonder if anyone still uses flushing oil. Or if it is even obtainable

Yep. Still available. wouldn't use it though. Modern high performance oils keep the gunk in suspension and it's trapped in the filter.Water contamination is the problem with engines that are not run up to temperature regularly. In extreme cases condensation build up in the crankcase will eventually dilute the oil. Run the engine up to operating temperature to evaporate the moisture, a short ride will do it, and change while hot. As commented previously change oil more often if you don't ride much.

You can still get it,but is frowned apon by those in the know - but those in the know don't work in the real world.If I get a real nasty one I will use a flush or just a water soluable degreaser like Turgosol,this will take out the water as well.

I once read something an oil expert had to say on a US site - on start up an average engine (V8 I presume) produces 3 litres (quarts) of water vapor,scary eh?

12 months no oil change--scarey

How frequently should it be changed?
Currently I do 3-4 thousand km per year.

Is that a two stroke bike, by the way?

FXR's are four stroke. It's cousin the RGV is two stroke.
Can see some spec's here. http://www.fxr150.ws.net.nz/index.php

I change my oil once in a blue moon. The krappisaki gets left overs out of other bikes and it last had a filter change about 5 years ago.

Doesnt make any difference now if you use hot or cold (I always thought modern bikes run oil at 60C anyhow).

Modern oil works as a cleanser as well as a lubricant and separates muck from the oil (diesel car oil suspends, normal oil doesnt). So you dont really want the bike sitting because you wont get the muck out of the bottom of your sump.

I think the biggest thing is the old wives tails havnt caught up with modern technology.

Some of my bikes you change the oil while you are riding it...

Just top it up when you stop!

That's standard for Briddish bikes.

They have a separate oil tank and a total loss oil system. The oil is pumped from the tank to the engine bearings etc, then squirts out here there and everywhere. Makes me laugh when people talk about buying chain oilers, for years all the bikes I rode had an automatic chain oiler . T'was touted as a special feature on some with a feed from the primary chaincase, on the others the chain just got lubed by the general oil mist that surrounded the bike and lubed everything in sight, including the rider, and any pedestrians silly enough to come close.

Pommie ingenuity old chap. Chain oiler, paint and chrome protector, rear tire lubricant and boot waterproofer. All fitted as standard and we had it 60yrs before anyone else. Buy British, help support the immigrants.
