No banter or argument..torque specs are derived from engineering calculations, period. For Joe Blow off the street to challenge the accuracy of a torque spec is fuk'n ludicrous no matter how many times you think you've done something "correctly"...I'm not sure why, I know why but I'll keep it polite here, everyone wants to banter back and forth about threads stripping, bolt shear etc.
All we're talking about is what is the maximum amount of pressure the cover needs to exert against the seal to prevent leakage.
In my experience, with the hundreds of times I have had to put one back on, 80-90 inlbs is all that is needed to provide an adequate seal.
I'm done folks do what you want....
Question: What is the correct torque value for any bolt on your motorcycle?
Correct answer: As per manufacture specification or instruction..
I would go on with the incorrect answer, but that's already been covered.
