Hi all, brand new to this game.Just put together my first bike( An old Murray beach cruiser single speed with coaster brake) and im having some issues. when i measured the chain and broke it, the chain was pretty tight.In fact it was too tight to install the tensioner. So i left it off, thinking eventually the chain would stretch. well, i tooled around the block on it and when i pulled into garage, the chain was very loose, so loose that it comes off the rear sprocket. Now the engine didnt move, and the rear wheel didnt move. Can anyone tell me how this happened? Everything seems to be tight and in the same position it was when i first installed the chain. At first i was thinking maybe the rear sprocket was off center. But it doesnt get tight then loose as the the wheel rotates, its just loose. Any help in telling me where i should be looking would be greatly appreciated. Also if anyone has a pic of how the bikeberry upgraded chain tensioner is supposed to be installed, that would help too. Thank you
