5-7 lbs. Follow the "general" torque guide for the size of the part.
The 10mm nut is 7.2 lbs. and the 12mm nut is 15lbs.
But I don't use 15lbs on the 12mm nuts 7 seems fine.
5twins offered a good tip in if you put the triangle one on and look at the bottom, sometimes there is a small gap that can be eliminated by simply rotating the cover to the next hole.

I never had to torque these at all, just hand tighten. But if there is a spec, I'd like to see it!

In all Yamaha service manuals under torque specification.
The first chart is "torque" by size. 10mm nut or 6mm bolt is 7 ft lbs, etc.
The second chart is by part description.
The online manual at bikernet will have it.

thanks weekender, I just found my manual and you are correct. pg. (10) 61-62
thanks for the response men!

Yes, there actually is a torque value given for these on that page. They're not referred to as "Valve Covers" but I can't imagine what else this spec would pertain to .....
