the chain tensioner that comes with these bike kits seems like ****. just went to the store not even 2 miles away and almost lost the 3rd chain because on the supped thing. do i even need this or is there some other alternative i can use?
Your motor sprocket is oval? Never seen that but as also mentioned a little loose will work but not a crooked rear sprocket with lateral wobble and the worst of all of course is the 2 sprockets not aligned to begin with.If the sproket isn't centered the chain will go tight then loose....tight, loose...
Not quite, my small sprocket is oval :-(!
I know the feeling, especially when I tend to ride high end shifters which by the way are harder to build than than a direct drive but you don't have to mess with the rag joint rear sprocket ;-}... i feel lost not able to ride.
