So i picked up a set of Hepco&Becker Crashbars for my 2014 GRiSO 8V SE, but i don't have the right Size hex key. My set tops out at 8mm. Looks like it might be 10mm or bigger. Anyone know the exact size? Also, does anyone know the torque specs for the engine mount? Want to make sure she's on snug enough. Just a blind squirrel trying to get a nut here!
