Good Morning All,

Going for a ride yesterday I had two things happen:

First is the idle never came down below 1000 RPM, all day. Warmed it up first thing in morning, normal idle at about 800 rpm. We get riding and at every stop sign or slow speed I pull in the clutch and it idles at 1100 rpm.
Never went back to the lower idle speed all day. This morning it warmed up and idle at 800 900 rpm. I didn't ride it today as I needed my truck.

Second is now I can really hear a howling from back tire as I take turns or even shift my weight a bit while riding. Higher speeds, the louder the howl. Tire pressure set at 41 psi, no obvious tire wear or damage.
Stock tire, Dunlop? No obvious handling issues. Is this tire a goner???

Thanks for your help
