Crankcase Vent Location

  1. I have some clearance issues with my choke lever that is preventing me from making a good PCV / Oil seperator. I noticed this bikes PCV appears to be connected to the previous WC1s PCV location. I have blocked this hole off & am wondering if it would still vent the crankcase as good as the NEs new comp release PCV location????? If so it would work better & have a much cleaner install for my bike. Is this location acceptable???????

    I believe you will find that the original WC-1 vent location is too small in diameter to be effective. If you are able to enlarge the opening I see no reason that it won't work.

  3. Enlarge the hole

    If I did use the previous location - I would enlarge & tap the hole to screw an elbow to connect an oil seperator. It would not go back to the air cleaner. What I need to know is that if this old location is as effective as the new one??? It looks like it could be just as effective.

    It will take someone a little more knowledgeable than me to answer that question. Sorry

  5. Location, Location, Location...

    This location is going to be best for my application. Got a tip from Gerd, (who owns this awesome black bike) Quenton (who you all know) oil seperator - plus efficient return to the crankcase / not via the carb or dump into the exhaust. Seems to make the most sense. I love working on this motor.
  6. Just waiting for a Q.

    Thanks Quenton. The clutch lines up exceptionally now & the intake manifold that you made is tapered perfectly for4 this motor. Why have'nt any other vent builders chimed in here?
