What are supposed to use to adjust (unscrew and screw) the drive chain adjusting bolts? I don't know if I have anything that can fit in that space between the metal covering surrounding it. Pliers? Wouldn't that just strip the bolt eventually?
When you sit on the enertia with an about 155lb rider, is the play supposed to be minimal? I adjusted it tonight and it seems to be around 1/2 inch play with me sitting on it.
