I am close to buttoning up my CL160 D engine which is really a CB engine. There is a real lack of torque spec info in the FSM for the complete engine!!! Torque specs are just left blank. Zero info on cylinder head nut torque values!!! What are other 160 owners using for values or have you been able to find Honda recommended values somewhere ?? @EzPete @Flyin900 Thanks for any info!

This is what the Clymer book has. I figured it’s an M8 stud, so that checks out.
On everything else I went with the standard torque values based on the generic service manual.
M6 - 9-11
M8- 13-18
M10 - 30-40
M12 - gudentite (German torque spec)
Pete , thank you !! Just what I was looking for. I do not have a Clymer…..only the Honda FSM. Does the common /generic service manual go back far enough to cover these bikes from 1960’s and 70’s??
I think the early FSM’s were designed to be used in conjunction with the Honda common service manual - the shop I worked at eons ago was independent but leaned heavily Kawi, so I don’t know for sure - it just seems like there’s whole sections that the FSM for the model was designed as a supplement.
Here's what I have from a FSM for 125cc to 175cc Sloper twin motors. The torque sequence is different than the other top plate bolt tightening sequence shown previously on what is an upright motor. I always work middle to the outside of my work anyway.
I use a very light oil to lube the studs prior to final assembly of the cap nuts with just a small amount on the threads.
I use 192 inch lbs as my top number achieved with 3 pulls of 96 inch lbs first, then 144 inch pounds second all after letting sit for 6-8 hrs in between pulls. Last pull is 192 inch pounds usually the next day.
I have never retorqued or had any issues with the above procedure that I use.

Flyin thank you for your technique described above! Very helpful info!!
I’m now curious if we have The Honda Common service manual in our VHT library that would cover 1960s bikes? Maybe @ancientdad or @LongDistanceRider would know??
Of course we know
but unfortunately, the copies we have are from 1988 and 1995.Thanks Tom. 1988 likely not applicable to 1960s….!Of course we know
It’s got more useful information in it than you’d think at first glance
