Change of rear sproket

Discussion in 'Modifications and Projects' at netrider.net.au started by f1worldchamp, Oct 17, 2008.

  1. Hi guys
    I'm looking to change the rear sproket on my KN150 from the standard 43 tooth to 39 tooth, and I'm wondering if I need to remove some links from the chain?
    I've been told it's not necessary, but isn't it going to leave some slack in the chain? Or is the slack taken up by adjusting the rear wheel location?
    Also, if i do remove links, is it as straight forward as 43-39=4 so remove 4 links?
    Thanks in advance.

  2. First pull the wheel back all the way and see if the chain is still too long.
    If it is take out 2 links, an inner and an outer by grinding the head of both pins on the offending outer link and levering the plate off with a flat blade.
    You will need a joiner link if you havnt already got one.
    Any probs post or PM
