If you are slackening the chain, you will have to push the wheel forward. Important Improper chain tension will lead to early wear of transmission parts. Make sure you have adjusted to the same setting marks on both sides of the swingarm. Refer to pointer on slider (3, fig. 56). This will ensure perfect wheel alignment.
