Could be, I never get up that early, I hate early mornings but may be
the ride in a TR makes it more enjoyable.

Doesn't really matter, I neyer noticed any influence on anything, but of
course I keep a clamp on them as well.

Its the tach. sticking cable shows up as erratic movements of the cable.
Anyway you should probably take out the cable and lubricate it. I use
grease, you can use engine oil as well. You can clean the tach but its
easyly damaged so if you are worried you should let someone else do it.
(I opened a coupe of them, the only thing that I can repair is the
odometer.)
