I'm new here and I recently built my first motorized bike about 2 months ago and everything was fine until I had to replace the rear rim & tire. I had hit a rock and bent the rim. After I replaced the rim, the chain came off (the tensioner bent back towards the spokes) and it got ugly. Busted the spokes, bent the sprocket and busted the tensioner.
I haven't ordered a new sprocket and tensioner yet, but here are my questions. Why would the tensioner keep pulling towards the rear tire spokes? It did that once before the accident happened, I caught it in time.
Also i noticed that my chain keeps touching when the clutch is engaged. (Picture provided) what would cause that?
And last, when I took the cover off on the motor where the other sprocket is located, this little "piece" fell out. Is that also broken? Or is it supposed to be like that? When I first built the bike, I don't remember the little bar being loose. I provided a picture to better understand what I'm trying to ask.
I'm still learning so I probably sound like I have no idea what I'm talking about.
Thanks
