When I changed from 15t to 17 tooth on magician chain was to short had to get new chain. Bunch of things could be at play here to tight axle. Spacer missing Well other posts several considerations.

I guessed a 12 or 13mm bolt which is 40 or 45 on a guideline sheet. But that does not take into account for fastener type, use of thread locking compounds, etc. Axle bolts need to have a recommended specification from the manufacturer. I have not found any technical documents anywhere for anything, which is my biggest frustration. My search prowess is limited I guess. Now I read on this thread there is a manual for a motorcycle with "make you dead" inaccuracies. Ugh... |

Go ahead and tighten that rear axle bolt to 65ft-lbs. Be amazed at how your thin box steel swing arm deforms. I will stick to using the CSC torque specs on my Hawk. Several thousand miles of doing so without issue.

The manual is incorrect. 65ft/lbs. is too much for these bikes. I'll stick to the 35ft/lbs. I've been using since I've bought the bike.

The 40 something lbs I went with at assembly seemed like a lot and the value came from a Honda service manual torque guidelines list. Still felt like a lot of force for a small bolt. Common sense goes a long way, and unless someone has physically clicked the value on their wrench they will never know - I'm windbagging sorry but if someone actually set their torque wrench to 65 ft lbs and went that far, "damn that's too tight" should come out of their mouths. |

Oh, and I know I'm annoying everyone but forgot to add that the value in that manual was almost certainly not converted from Newton Meters (Nm). Still a little on the tight side but much closer to general specifications for a 13mm thread diameter (47 ft lbs).
