- 3. Tip in Michel (the corner of the expert)

* "Hi the artists of the key 10! This little cylinder head cap, he looks all stupid, but his engraving '1.8 Torque' is there to save you the bet. The cylinder head of a Rotax is aluminum, a tender material. If you tighten this plug like a deaf to the eye, you will make the net of your cylinder head at all the blows, and there is the drama (and a new cylinder head to pay) !

My old old trick: always use an O-ring or a new sealing washer Whenever you touch this cap. Do not go back with old crushed seal.

For tightening, if you do not have a small graduated torque wrench at 1.8 n · m under hand in the stands, make a tightening 'contact' by hand, then give just a small quarter turn closed to the key, without forcing with the wrist. It's very enough to crush the gasket and make the circuit tight without attacking the aluminum! "*
