    Where can I find a proper video on chain slack on the BMW/Husk bikes?

    And is there a BMW-Husky subforum?

    Ok good. Found the slack for chain, 5 mm. Wow, that is really tight. I realize the pivot doesn't cause chain tightening but do I really keep it at 5 mm?

    40-45mm in the mid between front and rear sprocket. 5mm? Im surprised your outer bearing hasnt gone in pieces.

    Yes, the correct spec is 5mm thanks to the constant geometry through the entire stroke with the CTS system. That being said, I run mostly off road and had my concerns. I have always run about 15mm total up/down and had excellent results with minimal sproket wear or chain stretch. You can't run it loose like a traditional dirt bike because it will certainly toss the chain at some point so give it some slack, but not too much.

    Thanks for confirmation on 5-15 mm.
    You know where I can get a service manual (not owner's manual?)
