When using it, on a case-by-case basis
I used it in APE 100 Engine.
Crankcase On the whole Rose, lay it down (Horizontal placement) I bought it as being available.
On the whole it is a good product, but the hole in the Main stand's Bolt and Case side is slightly misaligned, the Knock Pin on the opposite side of the position of the photo does not go well and a shift occurs in Case. When I forced it halfway, Torque wrench did not work, I screwed the Flange bolt for matching Case. After that, I unloaded Engine once.
Clutch It is very easy to use if you have to replace it, but be careful when using Case breakdown. Do not tread the same rut.
