so the other day i had to take a 100 mile r/t on the bike during work. since i wasn't planning on a long ride this day, i didn't have any ear plugs with me.

while on the highway, i noticed a whining noise at speed which i had never noticed before. noise begins at 5000-5500 rpm (about 60 mph indicated in 6th) and increases in pitch as engine speed increases.

noise disappears if clutch is engaged while moving, and doesn't appear when revving engine while stopped.

so, maybe this is normal driveline noise that i just never noticed because i typically ride with earplugs, a budding transmission issue, or something else?

any thoughts?

Gear noise. Next time you're due for an oil change, note the amount and size of any metal bits in the old oil. Either do it yourself, have a buddy help you, or ask the shop tech to give you the old oil. If you can get that oil into a black plastic pan and hold it in sunlight with just a thin film of old oil on the surface, you can see right away what's going on. Anything larger than a light amount of "glitter" is an indicator of excessive wear.

You're most likely fine though.

was thinking the same. dunno why i'd have excessive gear wear, but just the same...

will change the oil tomorrow. maybe it doesnt like 5W40 and wants the 15-50....

it was hot last friday. maybe thats the connection.
