Clunking sound when pushed around
This morning I got to work and parked my bike, then decided to roll it a few feet to a better spot. I noticed a clunking noise while it rolled, several times while moving just a few feet. It was turned off and in 1st gear with the clutch pulled. If I rolled the bike back and forth, I'd hear several clunks. What could this noise be?
The chain should be lubed enough, although I have been on a bunch of dirt roads recently. It was adjusted just last week. Bike has 10k miles and has mostly been untouched besides oil changes, chain maintenance, and the 600 mile check.
I think I'm going to check the front sprocket at lunch. I can't take any pics or video on the company property, and I have plans to ride 100 miles tonight when I leave so I'm hoping there's nothing to really worry about here...
Any advice is appreciated. Thanks.
