Since the exhaust at the vertical cylinder will be so tight the current CNC Racing crankcase breather would not be able to have a hose fitted… This is because the hose fitting on this breather is located off center.

No problem! If the breather could be rotated then the issue would be solved. So I turned down the outside mounting tab of the breather and constructed a custom hold down bracket. Now the breather can be mounted any way that fits the build.
