This started immediately after I changed my gear oil...
Scooter starts and runs fine. Shifts from N to 1 fine, but when I take off I get this "jingling" sound. Sounds like loose change bouncing around in the engine. I'm assuming this isn't good. Gets louder the faster I go.
Also, when in Neutral if I roll the bike, engine off, it makes a noise I haven't hear before. Like a gear winding, noise. Like it's not completely in Neutral. Although the bike doesn't seem any harder to push.
My complete lack of experience and knowledge says "clutch" to me.
