Re: new to forum
By now I am sure you got your chain out of the drive gear, sometimes you have to work it out, if it doesn't take off the cover.
As far as the chain tensioner goes, a piece of innertube will solve all your tensioner problems.
But my tensioner wheel is wearing out badly (groovy man!), so I may modify the thing myself. Got my eye on a busted skateboard for its wheels. And I found this nice little bar of aluminum I may use for it.
I love my Motor Bicycle, I love Beer, I'll try not to like them both at once.
