How the hell can someone crack and break off the oil pressure switch port mount in this position with a sledge hammer and chisel?
It was not anything like that, it was in one piece when I got it.
Just a big crack migrating from the outside of the lug from up to the top and across the gasket surface.
I believe it was from corrosion and over tightening of the fastener. When I probed the crack it chipped off in one piece (very weak)
If you look closely at the picture you can see a tiny crack on the other side, not as big or worth repairing (just use the correct bolt torque!!)
Its hard to see in this picture, you can make out the line across the gasket surface.
You can see there is a lot of corrosion on the upper case where the engine/bike was stored out in the rain/snow.
When I went to take the clutch springs out this is what I found :
Was working on the cam sprockets this morning. Want to slot them for adjustment so had to take off the plastic bits.
Got a propane torch out and heated up the plastic enough to pry it off.
Measured some APE units to know how much to lengthen slots.Was thinking on using my 4" rotary table to cut the slots but it does not have a chuck on it yet. Will need to make a plug to center it and a base to clamp the sprockets to the small table.
