- The trick in Michel (the corner of the expert)

* "Hi the mechanos! The nut n ° 20 of the exploded view, it is the m8 nut with 12 mm base that plates your cylinder R3 against the bottom-engine and closes your cylinder head. As the cylinder heats and undergoes a huge thrust each Explosion, these nuts work enormously in extension.

My stand trick for a perfect and deformation cylinder tightening: cross tightening at torque wrench !

When you go up your cylinder or your cylinder head with these new M8 nuts, never tighten them blind with a flat key to PIF. First approach the 4 hand nuts, then apply the tightening torque advocated by TM Kart (usually around 22 to 24 nm) in stroke (in x) and in 2 or 3 progressive passes (for example 12 nm, 18 nm then 24 nm).

This ensures that the base joint (marker 16) crashes 100% homogeneously and that your Nicasil shirt is not twisting. A set of new base nuts and a tightening to the torque is the key to preserve your high-engine! "*
