Hey guys! I'm new to this stuff but I managed to piece together my own gas bike and it worked fine for a couple of days. Suddenly both the chains on my bikes popped or something. The chain for my pedal sprocket came loose even when i attached it back properly it had more slag then usual. Before it was perfectly tight. Secondly the chain connecting to my engine now started to make a click and get kinda stuck. Even when the clutch was disengaged it would roll then click and become hard to move then just start rolling again fine. **** I can still actually use the bike but I dont wan't to out of fear of damaging it and just general danger. I checked the clutch, chain tensioner and double checked my chain alignment. Everything seems fine? The **** could it be? If anyone replies because I dont know if im wasting my time i will post pictures and videos. Thanks in advance anyone!
