Over filling with oil...

[Rob W]

I did the old oil and filter change today, filled the bike with it's 3.0L and the level looked fine. Took her out for a blast and when I came back I noticed that the oil level is still sitting mid way up the sight glass, where as before it would be gone until it cooled down, so obviously I've over filled it (even though it had spot on 3.0L).

Just wondered whether I need to drain it ASAP or whether I can ride it until tomorrow when I can get it done.

Cheers.

Aren't you supposed to be able to see it midway up? never had a newfangled sight glass so wouldn't know.. have a check now its gonna have cooled down...

If its overfilled it shouldn't do much harm, unless its really badly overfilled it will do allot of damage (too much pressure in the crank case afaik) as it is theres probably nothing to worry about (still dont just leave it if it is wrong)

Chances are there was still some oil lurking when you drained it, suppriseing how much can still be in the enigne in passeges e.t.c...

Sounds as if the oil is circulating in the engine much better. If it stays at that level then that is how it should be.

There's usually 2 fill amounts. One for just an oil change and the other (larger) amount for oil and filter change. Which figure did you use?

The only hassle I've had with too much oil was problems with the gears after a long ride (couldn't get neutral). So decided to do a change and everything was ok. Just me being careful though.

sounds to me you filled it while the bike was on the side stand, then checked it after the ride upright, hence two different readings

Hi

Cold oil takes ages to settle down to the sump, hot oil gets down to the sump far more quickly. Suspect you are just used to the oil being cold.

All the best

It's always worth reading how the manual tells you to check the oil level.

Some bikes have a sight glass with a mark, some have dipsticks (apart from the one on the seat ), some have a drain bolt to get the right level. Often you should run the engine then let it stand for a certain time.

Stands are a nightmare for checking oil levels. Even the forward slope of being on a centre or paddock stand can mess up the level in the sump. Get a mate to hold the bike upright on its wheels.

that was silly ...

but i did that two,, the way i sorted it. get a handwash bottle the one with the pump action head... wash all the soap out of it, then stick the long pipe bit in the place the oil gos and pump the head, the oil will come out and have a cum ready, may take a bit of time but works..

Some bikes have a bolt on the side of the engine that you can remove when topping up the oil that drains excess oil out.

If you have too much oil in the engine then the bike might cut out because it can't breathe, or you end up with clouds of smoke. Oil pressure will be higher but there is usually a bypass circuit to deal with this.

Biggest problem is if you have a CAT fitted, the excess oil in the exhaust kills them.

Cheers for all the replies people.

When I changed the oil, it was done on a paddock stand as I was lubing the chain as well, so when I filled it I made sure to put a bit less in to account for it being sat slightly higher. Once it was off the stand I sat it upright on level ground and checked the oil level which was spot on. Then when it was back on the stand, I fired her up and let it tick over for a couple of minutes to let the oil run round the engine.

Well, it's been running fine the last day or so, even feels better. And yes, I have been checking it on level ground with the bike up straight, even put a boat level on it to make sure it was spot on. Yesterday morning the oil level was sat midway between the two marks on the sight glass, so just about spot on, and again when I took it for a ride it had disappeared until cool. Doesn't seem to be showing that it's overfilled now since the day I filled it.

Strange.
