Just a quickie....

Check my oil level regularly and have noticed huge differences lately.

Normally check the oil level when the bike is warm on centre stand.

Was showing about half way day before yesterday and last night was off the scale.... level not visable at all :confused:

Checked again today and its just above half :nenau

What could cause such drastic differences in the oil level reading :nenau

Vodka :thumb :D

Is it the same (level) spot and the same length of time from engine off to checking level? If it isn't either of those, I'm stumped :o
 
It's that Burberry oil that you use :D

P.S ...... Make sure your bike is on the centre stand before you switch the engine of , then check the level after a few minutes , makes a big differance to mine :thumb
 
How warm? I reckon it needs to have done 5+ (preferably 10) miles before thinking about checking the oil. It doesn't need to be all that far off the vertical (fore and aft or side to side) to change the reading quite a bit.

Thanks guys,

I will try and do it the same for a couple of days to see how it fares.

That Burberry oil is a bitch to get now Mr Burton.... even Halfrauds have stopped doing it :D sold the motor as well ;)

Unfortunately, there are lots of places oil can live in these engines besides the sump...

If you run a short distance and stop the bike and let it cool down, a substantial amount of oil will be trapped up in the radiator (since the thermostat will not have opened yet) and you might get a false low reading.

If you read the oil level shortly after shutting down, a lot of oil will be in the various parts of the engine and will not have dribbled back into the sump, again resulting in a false low reading.

Best bet is to run the bike hard enough to open the thermostat, shut off, and leave it till cold before trying to judge the oil level.

We've been running these oilhead engines for a decade now, and I am finding that the less I check the oil, the less confused I get. I believe the 1200's are a bit better about this than the 1100's and 1150's, but there ya go.

We also try to keep the oil around the middle of the glass, rather than topping it to the top of the glass. Too much oil and you end up churning it up and vaporizing it, at which point it gets sucked into the airbox (at least in the US models, which have this system to prevent venting oil to the outside world.) On the 1100's and maybe the 1150's, there are little drainplugs at the bottom of the airbox. Not a bad idea to open those periodically to let the condensed oil out...if that level gets too high, the oil goes into the throttle bodies and the engine...and you start looking like a 2 stroke.

The most annoying thing is to top up the oil only to discover that you didn't need to and that you have now overfilled the oil...
(maybe that is less annoying than blowing up the engine for lack of oil, but it is more likely to happen.)

Vfxmark thankyou,

After reading your post the only sort of standard is to do it when it cools down after a good run.

Having checked the last couple of days it seems to remain around the half way mark.

I was a bit concerned because it has only a few thou ago stopped using much oil. Bike has done 32k now and runs real sweet. Wondered why it had started guzzling oil again :nenau

Thanks again
