Agreed w the above...
What comes with these mab kits, may look, and feel like a 'chain', but it's really just a close facsimile of what a chain should really be. lol
Best thing to do is replace it with a quality domestic chain, for reliability, and safety.
My chain has come off twice, and locked up the back wheel each time.
Cheap thrills! NOT!!!
It is just as bad, or worse, when the tensioner arm comes loose, because the chain will pull it into the spokes, with the expected results.
Are you running a rag joint?
It is a most valuable improvement to these mabs to replace that with a clamshell sprocket adapter because they tend to shift in their mounting position making it impossible to properly adjust the chain.
...check your chain tension in one position, then rotate the wheel 180 and check again... chances are it will be different. In the least, this is a horse-power thief! and as little as we begin with, we need it all ! lol
I am, so far, pleased with the Liquid Wrench brand chain lube, when applied as directed. It is the least expensive chain lube on the market, and here in CA is available at Autozone chain stores.
Be cautious removing links ! lol
...all of a sudden you'll find too many have been removed and u will need to run a 1/2 link to get going again! lol
I removed two links from my stock chain, and that was it...
IMO. best to re-position the tensioner before removing any more links... at least try that first.
Best
