My bike just started leaking oil. It seems to be coming out behind the sprocket. It's bad when the bike is running, about three drops every five seconds at idle. If you hit the throttle, more oil leaks out. Has anyone else seen this problem? Only mods are Sparks pipe and jets and a UNI air filter.

 

If it's new and under warranty, take it back. If not, it should be an easy fix. Sounds like it's just the seal.

 

Sounds like the same thing that happened to my yfz. I just took it in to the dealership, and they put a new seal on.

 

sorry to here your yfz leaking oil... i hope its on warranty
