First: 10 N·m (1.0 kgf·m, 89 in·lb) Final: 19 N·m (1.9 kgf·m, 14 ft·lb)

but then it says for the 6mm bolts on TOP to use

Torque - Crankcase Bolts ( 6): 12 N·m (1.2 kgf·m, 104 in·lb)

then this website says

on all 6mm bolts to do 12nm

I am confused. thanks!


looks like I found a chart in the manual that say all 6mm bolts are 104 in-lb

I've been going 10nm om all 6mm bolts as 12 and even 11 seem to pull the threads out of the aluminum sometimes. Better off not getting to that point
