wet sump solution 2

Matt is right... HIS sump mounted reed valve does that....

MY dual reed valves are NOT sump mounted valves. One is mounted on the back side of the timing chest , and my other is mounted on the end of the camshaft because early bikes had a hollow cam and a port on the primary side of the crankcase half at the end of the cam..


Here's where one of my breather's is mounted... on the camshaft port


Here's where my other breather is mounted on the timing side



Here's what my case looks like behind the timing cover
green arrow - breather reed hole
red arrows - 3/8" holes into crancase to allow air to move easily way above any potential oil height in the sump
yellow arrow- 1/4" hole drilled to lower the oil level in the timing chest so the breather blows mostly air


I did these modifications before the sump breather that Jim Comstock developed was invented... and you should just buy one rather than copy my madness...
