Good place to mention this again
Re: lack of oil
Get one of the screw-in thermometers that replace the dipstick. I ordered one on eBay, cost about $30 shipped from Germany.
I've had one on my bike for a bit and I usually see about 80-120C depending on ambient temperature and how quickly I'm moving. I mainly use the gauge as a way to make sure I've got enough oil in the bike. If it doesn't rise above 40c after a few minutes of riding, it probably needs to be topped off.
