Needs a clear container for the crankcase breather pipe...........but it obviously can't breath too well with the pipe being tight in the neck of the container. Better to run the pipe up the frame tube and then horizontally. clipping it to the mudguard terminating near the number plate with a slash cut end pointing away from the rear tyre. A 25mm diameter pipe will prevent high suction plus a gauze cover (a bit of stocking or ally mesh) just over the end will keep crap out.
