If it's drastically overfilled you'll notice the clutch slipping, not that i've done the same or anything :oops: just slowly undo sump bolt and drain a bit off.
Shouldn't do damage though as you're just over-lubricating parts making them too slippy i.e clutch plates.

hmmm, i think it can do damage if you overfill with oil, i seem to remember that if its overfilled the oil pressure increases and can cause a lot of smoke, just do as luke sugests and let alittle out of the sump plug...
It can make the gear changes difficult, and in theory puts a bit of extra strain on the engine.
Letting out the excess through the sump bolt is probably the hardest and messiest way to correct the level. A bit of plastic tubing on the end of a large syringe might be more appropriate, dipped through the oil filler, to suck up some of the excess oil.
Of course, whether or not you bother to do this depends on just how much you've over filled it by. If you've gone beyond the visibility of the sight-glass, then I suggest you do remove some. However, if you can still see the level of the oil, then probably not worth it.
Also....
did you start the engine, which will pump the oil into the filter and around the system? This makes a difference to the level, so if you'd not done that, and you think you've overfilled it, it's probably okay.
Thanks for the replies guys. I cannot see the Oil level at all so prolly need to drain it a bit. I have ridden to work this morning (9miles) and it runs fine though, although I have been finding it diffcult to get into neutral. Going to chemost to get a LARGE syringe....and something for my cold ;)
Thanks again for your help
You could of course drain the oil and start over?

I seem to remember that if its overfilled the oil pressure increases.
The oil pressure won't increase but the deeper oil level will splash about more and can lead to the bike smoking a bit.
If it's not drastically overfilled, unscrew the oil filter a few turns, a much easier way of losing about a half litre or so of oil, as unlike the sump plug you don't need to remove it entirely to cause a bit of oil leakage.

Aahhhhhhhhhhhhhh :lol:

Talk about making a long winded process of it mate! :lol: :lol:
I've seen a bandit 6 that snapped tha crank after it was ridden for a week with an extra litre and a bit. Owner thought that 5 litres was the right amount, we asked him about the sight glass and he gave us a blank look. How we laughed :lol:
I overfilled mine the other day, and now I think its empty again
It was literally 3 days ago...
any ideas guys?

the new pointy version sv needs to be less than half on the sight glass or it throws it into the air filter, i took my sv back to the dealer after its service complaining of too little oil and that is what they told me.

is there any signs of leakage?

Noufy, dont take any chances mate
Was a mechanic for a few years and laterly a senior techie with VW/AUDI/BMW and did a lot of factory training with the manufacturers
Over filling with oil WILL cause serious damage to any engine, as some peeps have mentioned, from fouling air cleaners to physically snapping crank shafts/con rods etc, if really over filled then oil that has went via breather pipes to the air cleaner and into the combustion chambers (the excess that wont burn) can smash valves and pistons and embedd them into the cylinder heads etc, honest mate, have seen the damage it can do to a right few engines
Dont want to be all doom and gloomy but drain the excess as a matter of urgency mate then you can ride in peace

That's a load of complete ****!
We always make sure that it is almost to the full level for our race bikes and never have any problems.
over filling is BAD, because its' splashing around, it will get foamy and have air bubbles in it and it won't lubricate properly

I think you need to be a bit more sure about how much was in it, and how much is in there now, to be honest. But if you think it's low, DON'T RIDE IT!
If you have lost that much oil in 3 days... Well, it'd depend on how many miles, if you'd done a Nick Sanders then that'd be less worrying... You're either leaking a lot, burning a lot, or both. Leaks, you should notice. If you've burned a litre or more of oil in a few hundred miles, then you ought to be able to see it in the exhaust- smoky. Exactly what would cause it, I don't want to say- don't know for sure. But I'd think bad piston rings, or damaged piston or bore, if it's that bad.
Does it usually lose oil?
It would appear th ebest advice is...get rid of it till it's at the normal level. Whether you syringe it or sump it....DO get rid of it.
It CAN and WILL do damage if there's too much oil running around in there.
I blew valves and pistons in my first CBR :oops: by overfilling it with oil. There was white smoke from the exhaust too which was a dead giveaway. Pistons blew and boll**ed the engine rightly. Believe me.

thats just what i was told :roll:
How much is it overfilled by? A friend ofmine lost his car engine because of overfilling - but that was by a serious amount. (3+ liters)
As for the only half the window I'd check against the max/min markers on the engine next to the glass. If it's not to the max then complain agian loudly.

noufy, overfilled mine once (easily done) but removed excess oil straight away by gently unscrewing oil filter..as previuosly stated.. so level dropped in viewing glass. too much oil will cause internal problems mate.

I cant be sure, but I will check tomorrow morning. Its not burning excessivly, theres hardly any smoke, only in the morning when it's cold. Running fine, no leakage. I just thought it looked low again last time I looked, might have been that I wasnt looking right, as I hate leaning the bike over (havn't got a paddock stand.) Will get someone to hold it up I think, or lean it against the wall tomorrow morning.

If you're worried about checking it, here's some tricks to make it safer... Bungee or otherwise tie the tip of the siedstand to something solid on the frame- crash bugs are good. Stops it popping up. Put the bike in gear. You can also put something under the sidestand to bring it closer to horizontal to reduce the amount of muscle involved, if you want- but make sure it's big enough that the stand'll definately land back on it.
Now, Go around to the right hand side, crouch or kneel down beside the bike so you can see the glass, and pull it towards you- I use the bars, but you can use anything really. it's all about balance, not strength, but unless you're really clumsy the bike won't fall on you- it takes a while to go past the balance point, and it'll be no problem at all to keep it upright even if it does, as long as you don't let it fall too far. If it falls away from you, the stand's fixed in place so it won't go far.
The bike will just about balance when it's in the right position... You don't need to be too precise, but I literally have it at the point where I can balance it with one finger. This would be a less good idea with a Rocket 3 :)
When you're done, lower it back onto the stand gently- you don't need to push it back, just let it slowly overbalance away from you and support the weight as it goes back down.
phew its ok, i checked and theres plenty oil in it.
i found I can lean the bike against the wall using the left bar end and it stays nice and steady :D

Drain it and start again then, duh.
Drained it using the Brakes bleeing kit, was easier to do in the cold early morning, Had about 450ml extra in there. She sounds OK :thumbsup: Thanks for all the advice guys :grouphug:
