Do not use a low-ended 12-pin 12-pin key key to tighten these black nuts M8. Privilege a sOUNGE 6 PANS OF 12 MM QUALITY which takes firmly on the flats without marking the anodization / black treatment.

As for the classic version, tighten your 4 base nuts imperatively cross (in x) and in several progressive passes with your torque wrench until you reach the TM Kart factory value (about 22 to 24 nm). A tightening of the couple is a perfectly sealed cylinder and a black look that remains impeccable! "*
