Re: more chain problems
First question is, are you running the kit supplied 415 chain? I've seen twists and kinks in some of them. I've seen rollers that didn't roll and chain that had a natural twist in it that I couldn't get out. It's the first thing I replace. Look for a good quality #41 chain available at Ace Hardware, Tractor Supply and Grainer to name a few.
The next thing is chain alignment. Is your tensioner guiding the chain onto the rear sprocket correctly? The tensioner wheel MUST be aligned with the chain path and not pulling the chain to either side. Get back to us with some pictures and details.
