There is a possible correlation, which I didn't think about until now.

I just figured given enough time and flowing air and centrifugal force it
would vanish.
The impractical bit with the spray on lube is that it's designed to
stick - so it won't vanish for a very long time. Get some brake cleaner
or similar stuff and get it off.
Thanks for the info.
Let's go on a bit - the used thread on your tire shows that you're
riding with very limited leaning. You don't need to be scraping pegs all
the time, but man has a 'natural' limit imposed by millions of years of
running - this is at around 17-20 dgrees lean angle and far away from
what your motorcycle does.
I read some place you're a pilot - so you should have some familiarity
with lean angles around 30 or so degrees. Go there on your motorcycle
every now and then, so you can do it in an emergency.
Will do, thanks.
Thanks for all the good advice.
Actually, for a private pilot license, they make you do banks up to 45 degrees. The exercise is called "steep turns", and you have to do a 360 degree circle with a 45-degree bank and within 100 feet of altitude and also with some airspeed tolerance (can't remember what).
The exercise is interesting for a lot of reasons. One reason: you have to add quite a bit more power to hold airspeed once you start the turn. The airplane isn't very efficient doing a sharp turn. Second reason: sometimes you can intersect your own wake turbulence near the end, which terrified me the first time I did it.
First time I hit my own wake the whole plane shook and I just about peed my pants and I said to the flight instructor "What just happened?". He smiled and explained it. It is a shocker if you're not expecting it.

Also interesting is the control laws required to hold altitude (the first video above hints at that). My experience has been that you need to stomp on altitude deviations quite quickly ... by the time you're 20 feet off you should already being applying a mild correction. It gets harder to correct if you let it go longer.
