YZ250F leakage, help!

(Click here to view the original thread with full colors/images)

Posted by: blaze123---------------------

I just upgraded to a 250 4-stroke, so i'm still learing all about it. As soon as i parked it in my garage, it started to leak oil over night. i thought it was just overflow because the previous owner put all new oil in. However, it continued. It happens right under the shift lever near the footpeg, it looks like its coming out of the bolt right under the lever, but i cannot tell. can anyone help? thanks

i'm not sure where the oil drain plug is on the yzf's but on my rmz its kinda near the footpeg, mine leaked oil one time after i put a new plug in, you just have to get a rubber gasket to put in there and it should stop, the threads get worn the more you change the oil

blaze.

Could be the shift shaft seal. Using a good degreaser, clean the area around the leak and then let the bike set overnight. You should be able to see where the oil is coming from the next day. Shift shaft seals are easy to replace.

Have you changed the oil on the bike yet? The two main drain points on the YZ 250F are (1) bolt by the shifter and (2) bolt on the frame by the front tire. Both bolts are bigger (14mm heads I believe) and have a copper washer on them to act as a seal. Chances are you may be missing the copper washer on the oil drain bolt by the shifter.

It sounds like the copper washer is missing on the oil drain plug. First guess.
