Of course not, if you do it right. However, you have not really shown any evidence that you are the sort of person likely to do it right. The mere fact that you are suggesting it as a possible solution to you not checking your own bike after someone else works on it re-inforces that opinion. I will be happy to apologise if I have mis-judged you, but I do suggest you take another stroll down pit lane to see which bolts are wired and which are not. In my experience, the bolts that would put others at risk if they failed (oil, coolent etc) are the ones that are wired. The ones that would just kill you are your own problem. I have certainly never seen brake bolts being wired as it would take far to long to change the pads.

I could not agree more...
I actually agree with most of what you have written but the bit that worries me is...

That is achieved by applying the correct torque to the mounting screw. 
but in your own words, "but then again copper ease can render torque settings pointless".

Your only real objection to using loctite seems to be that
Quote:"There is now a danger (I think) that the loosening torque will considerably exceed the tightening torque and result in possible damage to the thread".
If you read up on loctite you will see it is true that the loosening torque exceeds tighening torque, but not to the point where is a serious concern.  Certainly, in my opinion, it is far less of a concern then using guesstimated torque on greased up bolts holding safety equipement in place. There are exceptions of course, but they tend to concern tightening torques that deliberatly strain the bolts and so do not apply in normal motorbike DIY maintenance.

Finally, you asked if Yamaha recommeded the use of loctite on these bolts, which seemed like a reasonable question. And even though I knew that they would, I checked anyway so I could quote it to you and according to the service manual I have (2001 5LV1-AE1 section 4-16) , I am quite embarressed to have to admit that they do not. 40Nm but no mention of loctite.  I would have put money on it, but there we go. And no, they do not suggest copper grease!
