For the materials I rely on the quality of OS manufacturing, I have made the design of the crankshaft and composition of the internal parts of the engine.
As I already stated before the 2 main reasons for the non DLC treatment.
1) The DLC treatment makes the crankshaft itself a little more flexible(softer). This will make the engine a little less direct on the throttle in the low rpm area.
The quality of the non DLC crankshafts in the OS production are excellent and the big-end holds up very well, of course not as long as the DLC crankshaft but for me enough to pass 2 piston/liner sets.
2) Because the crankshaft of the VSB01 is an unique design in the OS production this has made my price to obtain this crankshaft in my engine quite an important factor.
