Rattle sound & some trans oil leaking when motor running...

Recommended Posts

For the last 3-4 days of riding i could always see a little oil on my stand after a few turns on the track.

Changed the oil to notice lots was missing from the 0.85L my 2001 KX 250 so i started the engine again after an oil change and waited a few minutes to find it was as expected leaking from somewhere.

I wiped it and no more leak so it's got to be under pressure only.

So this rattling sound + oil leak tell you anything before i take it all appart to find what's responsible for this ?

Seems to be comming from somewhere behind the kickstarter or in that area...i can only see the trail of oil comming down.

Tell me i just lost a bolt or something quick to fix so i can start riding again...

Does the rattling change when you pull the clutch in? Oil leak sounds like clutch cover. Try snugging the bolts up a bit. If this doesnt help change the gasket. Much easier to find if you start with a clean bike although sometimes you can see a leak easier when dusty. The oil leaves a plain trail. Heres a trick for the novice. Clean and dry bike well, put on stand and puff out a bunch of baby powder on the suspected area, start the bike on the stand and get down on your hands and knees and take a look. The powder will help you find the source.
