There are a few things on there that for me are more of the "if it ain't broke, don't fix it" type. I don't regularly check compression on my bikes, unless I suspect something is up (and after doing tune up maintenance). Same for carbs -- if the bike's running fine and there aren't any leaks, no need to do anything.
Excellent remark. In general: don't overnurse your bike! Here's a example. Some think you need to replace the oilfilter element at every oilchange. Not true. The Honda schedule is perfectly clear on this. That filter is actually oversized. The difference between a new engine and one that is totally worn, is a teaspoon of metal for cars, for our bikes not even half a spoon. Many use aftermarket oilfilter elements. More then often you will find the big O-ring curled up in the package. This can lead to quite a hassle fitting that O-ring in the groove and keeping it there when you mount the oilfilter case. Tip: if you have such a filter as a spare, keep that O-ring in for instance a thick book for some time, so the weight will straighten it, so you don't have to fight a curled and unwilling rubber on onstalling and run the risk of leaking.
Personally I've never been able to conduct a succesful compression test, The last one was some 20 years ago and I had 5 kg. on all four. As long as my bike starts rightaway, performs as it should and recently shows a healthy 20-21cm Hg underpressure @ syncing, I see no reason to worry. Honda pistons and rings are very, very good.
In general. People have no idea how many miles you can ride these bikes, without needing one. Mine has done over 140.000 km and still has the original pistons. BTW, the other day I read about a Goldwing (1975-6) which had done 650.000kms and when opened for a rebuild, the mechanic judged that all it needed was new rings. Pistons still good. I have knowledge of a CB500 owner, who had done 220.000 kms and thanks to his dayly rides, his engine had not been opened yet. Nine of ten issues I personally had, had to do with standing,
not with riding.
