Scratching noise 3rd and up
Lately I've been hearing a scratching noise or metallic rubbing of some sort coming from the engine area. Like taking sandpaper and rubbing circles on metal.
I've ruled out its not chain, brakes, suspension, or steering.
It will only make the noise 3rd gear and up, at speed ~4k and up rpm.
If i'm doing 70mph on the freeway, I hear the noise, pull the clutch in to coast, no noise.
Can't reproduce it on the rear stand.
So far, I've replaced the clutch lever, clutch cable, clutch springs, and clutch plates. Basket bearings looked great.
No metal bits in the oil.
Performed valve clearance adjustment, no problem there.
Anyone experience the same? The bike is running great, plenty of power and great MPG's.
Thanks for the assistance!
*edit, Currently at 16k Miles, I DD 50 miles a day.
