Have two questions on this, hoping I can get some help. I am replacing the main chain on my moped, the one that (i think) connects to the pulley and to the engine.
-what's the best way to go about doing this? Do i need to both remove the pulley and loosen the back tire to get the chain on, or just one of these?
-how do i (cut) the chain to the right size?
-how do i know how tight the chain should be? The reason I'm replacing the chain is because the last one snapped, I think because I had the chain on too tight.
if anybody knows any videos or useful links that can help, that would be helpful. I can also send pictures of the moped if that helps as well, its a 1979 motobecane 50v moped.
