Happy Memorial Day everybody!
I Changed the oil and filter and the ambient temperature was about 70 degrees C this weekend. The air filter is new as well. The oil was a little dark and there was a tiny bit of foam. Last oil change was 4 months ago and less than 500 miles! (20w50 Mobil 1 vtwin Synth)
The engine still seems to be running really hot. (But well!)
Idle is at 1000 RPM
Laser thermometer shows the lower case at about 275c, the lower fins around 300c, the upper fins around 250, the exhaust pipe near the engine about 290c, after only about 5 - 10 minutes of running idle. (Same before and after the oil change) How do these compare to usual?
Everything sounds good, and honestly it seems to be running better than it ever has since I have owned it!
If it wasn't for the discoloration of the covers, I would not be concerned.
I checked photos of the bike from when I originally had it and the covers have discolored to a gold bronze for sure!
Can I assume that if the oil pump wasn't pumping that the engine would be making some terrible sounds and not run great?
I wish I could blame this on a hole in the radiator!
Any other thoughts?
