Ninja 250 Oil Leak Down Kickstand

Okay so I was an idiot and during my oil change I did not fully drain my oil. I just drained the oil from the filter bolt assembly, changed the filter, put the assembly back together and put 2qts in. I did not remove the drain plug and drain the oil from there. The next day I drove 50 miles and noticed lots of oil leaking from down the kickstand, the engine never gave me trouble and the oil light never came on. When I got back home I removed both the drain plug and the filter bolt and let the oil drain completely all weekend. Today I put it all back together and put 1.7qts back in. I then took it around the block, came back and parked it and it still seems to be draining down the kickstand. My question is have I done damage worthy of putting this bike in the shop? Or is this normal for majorly overfilling the oil and I should just continue filling it to normal levels until it stops? Any help would be greatly appreciated.

Thanks!

Holy mother of .


Do you have stands to level the bike so you can check the level of oil? Did you accidently over tighten the drain bolt or filter? Follow the oil from its coming from!

The oil is coming from the the crank case vent and probably from the airbox. You need to find the oil drain line that comes from the airbox and drain all the oil out of it. When you overfilled it, the oil came out of the crankcase vent and into the airbox.

What is the oil level in the sight glass on the right side of the bike? You want the oil level to be between the two marks on the sightglass when the bike is upright and level.

These bikes don't have all that much oil, so it is very important to add the right amount and to do the oil changes correctly.

If u over filled the oil it could of blown out the seal where your shifter goes into the motor. Check to make sure it isnt leaking there...or an over flow vent somewhere

Trust me. I realize how stupid this mistake was.

I didn't over tighten the drain bolt or the air filter. It has not been leaking from there. I think it's coming from the crank case and airbox like Flynjay said. The oil was dripping down the kickstand and on the bottom of the fairing by the kickstand. After letting it sit for a while after riding I stood the bike straight upright and there still appears to be oil as visible from the sightglass. It is slightly below the top mark on the sightglass so it looks like its holding most of the oil I put in it. Hopefully it's not a seal. I hear these little engines are tough so lets hope it's somewhat moron proof (me). Is draining the oil the from the airbox essential? or will it drain naturally?

I know him and have to give him a hard time. Hopefully it is ok now after the oil drains from the airbox (cross fingers).

All joking aside, you will be fine. Just drain the oil out of the airbox as flynjay said. You would be best for you to wipe off all the oil and trace the source so we could better help you.

Look in the box for oil. Clean all that chit up. Cleaning it all up is the only way you will know for sure that the oil isnt leaning from somewhere else.

Make sure to squeeze out any excess oil from the air filter as well.

I cleaned and drained the ail from the air box and got about 2 or 3 cups out of it. I really think that did the trick because it was definitely coming from there. Now I know if it still leaks then something more is wrong.

Thanks again for the help guys!

Did you check the oil level? Sounds like you over filled it.
