Overfilled, should I bother?

Corsara · Sep 10, 2011

So, I dumped 3 whole litres of full synthetic Yamalube 15w50, went for a ride, put the bike on the center stand, let it cool off, looked at the dipstick and oil is way above the markings. Is it safe to leave it like that?

Yeah i hear its not recommended. I think you can destroy an engine if you put way too much over the limit. I would try to drain some without unscrewinf the drain bolt completely but be careful it can get really messy if you dont prepare.

+1 on not draining. Overfilling can be as bad as not having enough oil. Drain some off and you'll be good to go.

I saw a You Tube video where a guy used the pump from something like a soap dispenser to drain off excess oil. He put it in where the dipstick goes.

I overfilled mine once. It starts seeping out and you can smell it. As mentioned above, I ended up sucking some out though the oil filler cap with a syringe I had for 2 cycle oil or mini air pump or something. Yeah, I believe it puts excessive pressure on seals which can eventually lead to seal failure but I'm just talking loosely. But, yeah, it can't be good to overfill with significant oil. You said you only used 3 liters? That's not much over if you drained a operating temperature engine of motor oil & filter. That's how much I usually pour in. Only reason why mine was overfilled was because I didn't adequately warm up the engine!

HAHA! I did the same thing the first time I changed mine too! Glad I'm not alone.

I 'spose you wiped the dipstick before you checked the level ?

LMAO!!!! I should have made you come over here to do it... :rof::rof:

Well, I drained about 200-300ml by unscrewing slowly the drain bolt...well, I thought I would just let it drip a little, but no, the damn thing wouldn't drip until completely off. Guess what, it dropped in the oil pan, and I stuck my index finger in the whole to stop the oil from leaking out (good I had nitrile gloves and the oil was not too hot..)...

I somehow managed to screw it in, and as a result I discovered that I drained exactly as much as I had planned. So far, so good.

I took the bike for a ride, and now I have this ticking noise, which is most pronounced around the 4k RPM in 3rd gear, but it's there in all gears, just can't hear it so much. I swear, it was never there before! Also, there's 2.8 litres of oil in the engine, right now it sits on the top of the marking on the dipstick.

Needless to say, I'm confused and worried...

I have heard a ticking noise in my top end ever since the bike was new, but I've never done anything about it. Bothers me though, and I was searching the topic when i came across this thread. Doesn't seem to change by oil level though...

Did that on my first oil change. I use Rotella 6T (4 Q can) All you need to do is put a drain pan on the right hand side of the bike (leave the dip stick out) and lean it... You don't have to remove the drain plug

Just for the record, I didn't put the whole 4Q of oil :BLAA: it was just a bit too high on the dip stick...:spank:

Thanks for the tip!!! It's too late now, but I'll definitely remember this.

brucey · Sep 10, 2011

when you check your oil level you don't screw in the dip stick. From the start: unscrew the dipstick, wipe it clean, then insert it without screwing it in, then remove it and observe the oil level. This is an easy mistake to make. If you screw in the dip stick then you will see the oil level as being too high, when it is actually at normal level. Call up a local mechanic and ask his/her advice, a good one will talk to you on the phone and check your oil level for free. I hope this helps. Yes, I will get a photo put up, I'm to busy riding!

Thanks brucey, but yes---I always check the oil level on the bike, cars, etc. without screwing it in. Right now it's about 1-2 mm above the top of the marked zone on the dipstick, and that measurement is taken with hot engine, parked on level ground on the center stand, let stand until it cools off a bit, and then wiping off the dipstick and taking measurement without screwing it in.

I use an over-sized "car" filter that's about an inch longer than stock and adding 3 QUARTS brings the oil level to the proper level.,, Rich

1978jeep258 · Sep 11, 2011

which car filter are you using? Is there a specific make and model of car or engine to look for?

FloppyRunner · Sep 11, 2011

I just wanted to add that I'm pretty sure overfilling the crankcase was what caused the brushes on my starter to get eaten up.

When I took my starter apart because it wasn't working a bunch of oil came out. The brushes were soaked in oil and there was excess "sediment" (from the brushes) inside. A friend at work suggested this and I drained some. I assumed it wouldn't be a problem since I didn't think I could have overfilled it by MUCH, but still. Haven't had a problem since.

This sounds okay but, it doesn't specify this anywhere that I know of. I speculate that this is because the level indicated is insignificant or within parameters whether the dip stick is screwed in or not. It's curious why Yamaha doesn't specify whether to screw in the dip stick or not.

Overfilled, should I bother?
