Oil Leak from Cap

[TLR_Nate]

After I changed my oil I now have a leak out of the cap. I have resecured the cap numerous times. It looks like there may be a mnimal gap but no more than before the change.

The oil does appear to be a little too full. I have never had a leak issue before. I always get good feedback here.

Do I need to drain some oil (suggestions on easiest way welcome) or should I try a new cap or both?

+1. Check to see if the ring is there at all, if it is, see if it looks cracked or generally deformed.

ummmm..... i have ran mine without a oil cap in place *(when changing the oil and starting the engine to circulate the oil)...and had no oil come out.... how many quarts did you put in??

and you probably just need a new oring on the cap..... ~.25cents @ any parts store..

O ring looks fine. Put in almost 4 quarts. Never seen the site glass so full. Think I put in a bit much. I normally have a little left over but did not use the rear stand when putting it in so may have put in excess.

May replace whole cap if not expensive.

With the bike standing up straight, can you see the top of the oil through the sight glass?

If you filled it to the full line on the side stand, it is too full, either use a turkey baster or a vacuum pump to remove some of the excess oil.

I guess you could have way too much in there and it is just slopping around the oil fill hole. Excess oil can cause pressure in the bottom of the engine which could be why it is leaking.
