the CBX has its highest RPM with 9600 (so the engine does somthing aroud
11000 without any harm). But it is good to know those things - thanks

I have no plan what that means? (my technical english aint that good).
Could you give more informations - what is meant by degrees

Whats a crank? And what do you mean with the timing wheel.A friend of
mine who was in the team that designed the BMW Z3 engine told me that I

-the CO2 after the zylinder and
-the vacuum before the zylinder
isn't that all - or do I need more data
