I'm new to the forum but have viewed many topics and threads on here so hello from 'me' as this is my first post.
I have a WR426 2002.
This morning I noticed a pipe leaking. The pipe starts from the top of the engine head (Next to the spark plug). The pipe is thick and then steps down in size as it passes the carb..
I think the other end should attach somewhere.
Please can some one tel me if it is a breather/overflow pipe or return pipe which should be attached!??!!
