oil level

Can someone please tell me whether the dipstick has to screwed in all the
way, or just sat in the top to check the oil level on a 1992 honda cbr900rr

This has been argued here before with many opinions and quotes from
handbooks.

The truth is, it really makes ****-all difference.

Normally with Fireblades the dipstick sits on the seat (or on a seat nearby bullshitting about how many track
days he's done).
.....hope that helps....

 

Well, on my bike, it needs to be measured with the dipstick not screwed in.
If I screwed it in, then I would be putting about a litre less oil in it. I
suspect that might make a difference.

And what would the difference be?

Speaking of which, are you in Melbourne yet?
Also, I think your surname is disappointingly short, considering.
'T' had better stand for something pretty amazing, given that
you informed me at Karuah that you were called TB because your
full name was 1023 syllables long ...

those damn kids^WDohertys^Wbeers!)

 

"T" is short for "Thousandandnineteensyllables".

 

about 0.8kg?

 

When I've topped it up, the equivalent of riding with the oil at the bottom
of the recommended range. If it gets much lower? I'd rather not find out.
I just assume there is some reason for those recommended oil levels.
Something to do with adequate cooling and lubrication perhaps?

The difference in the Guzzi, which holds 3.5 litres, is less than half
a litre. Helen's bike only holds 2 litres.

Interestingly, in the early '80's Moto Guzzi decided to do something
about the oil cooling and fitted a deeper sump (added a sump spacer
actually) but continued to use the same dipstick so had more oil in
the sump. This caused some foaming (of the oil, and subsequently the
rider) resulting in blowing it out the rear (breather). They fixed
this problem by remarking the dipstick about a litre lower.

As long as there is oil in the sump and it is above the pump pick-up
point there is no real problem. I would suggest there would be less
than a half litre in the sump at that point and indication would be
off the bottom of the dipstick.

I don't feel the need to be anal about the oil level being within 5 or
10 mm of an arbitrary point.

How many are there?

With all due respect, while that may be true of Guzzis it very much will vary
bike to bike. Depending on whether it's wet sump or dry sump, the design of the
pickup points the level in a flat shallow container varying a couple of mm is a
lot more crucial than the level in a narrow deep container.....big difference in
liquid volume, whether that delta in volume matters depends of course.

Do they screw in from above or below?

 

Depends on which way up the bike is.

-----sharks (five, if you count sump drain plugs ... and hey, if
the sump plug is dry, you _really_ need oil ...)

 

Yeah, dry sump. One in the top of the frame oil tank, and another
in the sump. God only knows why. The level in the engine never
changes, and the level in the tank varies so wildly you just can't
tell.

Been in Melbourne for a while now, since late July. Haven't got the bike yet
though. Called up to arrange transport for it and seems it wont happen till
next week and I can't afford to fly up and ride done...

They called me Basnayake Wasala Mudiyanselage Tharanga Basnayake, but I
think TB's easier...

 

The ZX-6R is like that. On the side stand, no oil, eeeeek. Try and
hold bike vertical while looking in window, oil appears (yay). Put
bike up on centrestand, no oil in window. How level the group is and
how steady you can hold the bike up has a big influence on the level
showing in the window (at least on my bike).
