81 honda bf100b torque question

[justinspot]

I have a 81 honda bf100b and I was replacing a bunch of parts and new gaskets , long story short is I have the service manual but it is very limited on torque specs. Is there a rule of thumb with these motors for the 6mm , 8mm varies length bolts for torque . Like I said the manual is very vague and only covers a few parts . Any help would be very helpful or if someone has a list of torque for these motor. I dismantled the entire motor for inspection. Motor looked great after replacing a few parts .
