Chain seems loose.. it popped off with me on it.. should i tighten it or remove a link ?

 

that depends, how much adjustment is left on the chain tensioner? if not many threads left, back the tensioner off and see if you have enough to remove a link or need to remove a link and add a 1/2 link.

 

You should tighten it. the same thing happend to me. so we tighnet it. and we found out tht those loop thing on the back axcle or what ever were the problem. because everytime you ride the bolts would get loose. after a while of tighting them all the time they broke. so i ordered new ones. thos broke putting them on. so we made up our own with bolts and washers. then boldted it on. then welded the in place so tht the chain never got loose again.
