Official service manual says 14 ftlbs for chain case but I never go that much. You're only holding the outer case onto an o-ring that seals it. The aluminum case stops the compression of the o-ring so tightening it more doesn't make it seal better. Just snug them up to the point where the case stops and that's good enough. If the o-ring is good and the case isn't damaged, it won't leak.Doing my first service myself had dealer do previous two yearly services bit always did them on my Apexs. What are the torque specs for the chaincase torx bolts? What are the torque specs for the torx exhaust bolts when I reinstall the muffler. I looked in the above stickys bit didn't see any torque specs. Thanks
