My idler sprocket came loose on me when I pulled the inner cover and I put it back and didn't see anything in the engine but would it go back together and start if it were missing a thrust washer? I took it on a test ride, seemed ok. Would the engine start and sound ok if a thrust washer had fallen in?
Noticeable change? No, but it won't stay that way. The thrust washer is there for a reason. You need to pull the bike back apart and verify if the washer is there or not. If not you need to find it. I've fished a few of them out of the sump. It isn't that difficult.
