I have a '92 ZXR250 that is doing quite the strange thing. I had an minor accident on it, involving me being forced off the road. And I have been fixing it up, and now when I start it there is oil leaking from the join between one of the exhausts and the engine. I am wondering if this would happen if the join was loose between the exhaust and engine. But I am also thinking oil shouldn't be anywhere near the exhaust... should it? Thanks alot! Sam.
