The confusion may come from the the 8mm bolt head with a 6mm bolt thread diameter, which is common to almost all side cover bolts on Hondas. Somewhat surprisingly, the 6mm bolts will stretch and snap, rather than strip the threads.

I use 1/4" drive sockets and ratchets on these to help prevent over-torquing, basically just wrist pressure torque. You need to be more careful with 3/8" drive, as it is easy to over-torque.

Most common torque wrenches do not read the lower and upper limits of their range accurately. With 6mm bolts, the torque wrench would measure in inch-pounds, not foot-pounds.



In this case that saved him a huge problem so all is well.

Use the factory bolts OP= I wouldn't substitute anything.

Not longer, not shorter, nada.

Yup. Most of em checked out with the torque wrench. But some were stubborn so I just tightened with the ratchet by feel. I rechecked the bolts on the side of the fall. Seems that some of them were ever so slightly bent. Ordered a new OEM set of bolts to replace some of the skewed, broken ones and some extras.

Update: Seems the seeping has stoped today. Ran the bike. a few mins, rev’d a little bit. Checked for leaks. I’ll just keep an eye on it. When I do the Valve clearance I’ll have the mechanic change all the bolts and re-seal those covers.

I swear I’ve had more trouble trusting the T-wrenches on Lower torque settings. On higher I guess it works out ok.

Saw a thread on a guy who was installing crash bars and he felt the torque setting was too high and ended up doing it by feel or a lower torque setting.

Thanks so much for the info guys! Appreciate all the help!
