Oil overfill???

Ok, I just changed my oil and filter (1000k service). It was very easy and all seemed well except for two things.

1 Most important, After adding about 28 ounces of Mobil 1 V twin it appears I've over filled the tank? Even thoug it calls for 32 ounces, I added 28 to be safe. Guessed wrong there I guess.

I drained the old oil. I pre wet the filter before installing it. I checked the oil with the dip stick cover fully inserted. Is that correct? I know the trans fill pulg is inserted just until the threads touch. I then rode around the block a few times and then let the engine idle a minute or two on the jiffy stand and then rechecked the oil hot. About 1/4" over full HOT. Hmmmm..........

Thoughts..............??

2 Not really important but I'm curious. The oring on the oil drain plug was broken and very hard when the plug was removed. Is this normal? I planned on changing it anyway. What's a couple bucks when you're doing this yourself. Do they get brittle like this all the time?

Thanks

Some of the oil stays in the engine on a setup like this. I am not sure of the capacity of your engine and such, but on my bike I always add 2 quarts and run it for a few minutes. Then I check it and add it up to the level it should be. If you are overfull get a turkey baster or something and suck a bit out till it is at the proper level. I usually fill mine to about 3/4 full on the dipstick as when I have filled to to full I got oil coming out of the oil filter meaning it was too full.

For the o ring on the drain plug sometimes it's fine, sometimes it's torn. I took a harley one to Home depot and went to the plumbing dept. I got a a package of them for $2. Same for the transmission o ring.

Run it for a bit and see if it is still overfull as the oil has to circulate through the engine and back into the oil tank.

Crap, I totally misstated the oil I added. I had a brain fart.

I added 3 quarts and 12 ounces at first. Not 28 ounces as stated above. Sorry

I had thought of the turkey baster idea. I'm gald to know it works. I guess I need to star t with an amount that's much more conservative next time.

If I suck it out when the engine is cold, should I do so until it hit's the lower "cold arrow" or just someting close?

Now that makes sense. I add 2 quarts to start and go from there. The amount stated for the engine is for a completely dry engine. There is usually about 1/2 quart that stays in the crank case when you drfian the oil tank. Turkey baster or some sort of large syringe should do the trick. The best way to learn is by doing something if you know what I mean. I ALMOST FORGOT. IF YOU LEAVE IT OVERFILLED THE EXCESS WILL COME OUT OF YOUR AIR CLEANER SO IT'S BEST TO SIPHON SOME OUT.
