Too much oil - issue?

[Wonko The Sane]

I checked my oil level this morning, I check it about once a month and it was off the bottom of the sight glass, but then it was also freezing.

Kawasaki do say the bike should have been warmed to the bottom of the temp gauge, then left to stand before checking, I warmed it for a bit then let it stand for a bit and then topped up to half way.

Checked it after riding to the petrol station and filling up and paying etc by work (half a mile) where the oil level was filling the sight glass so I'm wondering if I've overfilled it slightly.

The bike feels fine and going to check oil level in the morning again but wondering if it's a big issue or if it'll just throw the little bit extra up the breather and end up burning it?

I'd personally leave it if it's only 'slightly' as you say.

How much did you put in? Was it atleast close to what the manual says?

EDIT I: Drain the oil, read the manual, pour in the specified amount (all of it), don't look at the glass thinking it's too much or not enough.

If the manual says 3.1L you pour in exactly 3.1L, if it says less, pour in less. Either Way, read the manual. The number on your engine states the amount of oil that is in the engine. Bear in mind there's 0.1L in the oil filter and about 0.5L stays in the head, oil cooler and other places. So, if the number on the engine says 3.6L for instance, you only pour in 3.0L or 3.1L IF you remove the filter. You would pour in 3.6L only if you had a fresh built engine, that is completely dry inside.

EDIT II: If you are sure you poured in the right amount at the first place, and your motorcycle does not have liquid cooling system, then you are being paranoid as there's no chance something could make the oil level higher than it was the day you poured it in. The engines are mostly designed so when you pour in the right amount, you shouldn't be adding any oil before the next oil change.

EDIT III: If the one you own have liquid cooling and the cooling system was leaking into the oil, you'd see emulsion, which you don't as you'd be asking a completely different question now.

If it is still bugging you by the morning I would dump it and fill it with fresh.

As long as the oil level isn't high enough for the crank or any other moving bits to be splashing around in it and making foam, then you're probably good. I overfilled my BMW when I did the last service so the oil level is a cm above the max level on the sight glass and 1,300 miles later it's still absolutely fine.

The ZZR is a total cock for checking the oil level. If you are not on perfectly flat ground it can appear over/under depending which way the bike is microscopically leaning.

I found this out when it drove me to OCD, (because depending on where in the bay I parked it looked like the bike had either burned most of its oil or magically topped itself to the brim) and I checked the oil at various points of my parking bay with a spirit level on the bike.

TLDR - It has oil

Unless you have put like 50% too much in don't worry just use it

In nearly 40Years in the bike trade I never seen a bike ave problems with too much oil I have even had ER5 come in having had flooding problem and drained 10/12 Liters out instead of 4 !

so just don't worry the "it will blow the seal" " it will kill the Lambda sensor" tales are rubbish

There is always one that on a common engine taking 3 / 4 L would require 15/20 l !!

Still seen way more dammage from too little than too much
Me I always overfill my own bikes at least 20%

I know my bike looses a bit of oil over time which is why I check it every month but top up every couple of months if needed. I hadn't just changed the oil, I know it swallows 3.7L

It's been ages since I topped up, probably since Nov as weather has been crap when I've been at home during the day and can't see at night to do anything.

Just been out to check it 5 mins ago on centre stand and it appears to be just above the level of the sight glass although as someone has said, the ZZR is a pig for any slope on the ground causing a change in level.

No sensors in the exhaust or anything to cause issues, feeling more chilled about it now you've confirmed what I was thinking and that I've seen it's only to the top of the sight glass and not higher.

Try cleaning the engine and provide proper racing. There is an oil available from a german company(I suppose it is mobioil company), it is the perfect to clean out the engine.

Top tip: If you're worried you've overfilled..

Unscrew the pushy-downy bit from one of these and stick it down your filler cap.

Waaaay overfilled will froth in the crank case but if it's only a midgets's piss worth then...meh. As already stated, you can siphon a smidge out using various methods. I've used a turkey baster with a bit of silicone tubing slid into the filler in the past.
