So, there is a small curved pipe on the front left bottom corner of the engine on my R50. The Clymer manual doesn't say a word about this vent, I have some ideas about what it is and what it is doing but I am looking for a more detailed description.
Also, after replacing both head gaskets the bike is running a bit rough. it is difficult to start, it feels a little sluggish at low RPM, and is slow to pick up. The exhaust is more white than normal, and the Mystery vent from in my first question is blowing out a bunch of white / gray exhaust.
Is this a carb tuning problem or is there something else i am missing?
