Hello, I'm trying to figure out why my Maxi's starter clutch will not engage. I was riding it a couple of days ago when it suddenly wouldn't accelerate. The engine was revving really high and didn't turn off, but the bike didn't move. I turned it off and tried turning it on again but the clutch wouldn't engage, even with the cable tightened all the way or by manually pushing the lever as far as it would go. I am not getting any resistance when pulling the clutch and pedaling or moving the back wheel.
I took off the clutch cover, and everything at least looks normal. Clutch is not moving freely on the crank. Clutch and springs, bell, starter clutch all look ok. The bell's gear is aligned with the main gear, and spins when moving the pedals. Got any ideas?
Some pics attached. Thanks!
