Mikes XS – Yamaha XS650 Cam Chain Adjustment


I’m Ethan. Welcome back to Mike’s XS Nation. To complete this project, you’ll need a twenty two millimeter wrench, a seventeen millimeter socket, a twenty seven millimeter socket and a thirteen sixteenths spark plug wrench. So let’s get started. The first step in completing this project, you will need to take off the left hand stator cover. Which is the smaller cover that covers just the stator, and remove the spark plug, so there’s no compression in the motor. For your convenience I’ve already removed the left hand cover so the stator’s exposed and available to get at. Your next step would be to remove the twenty two millimeter crown nut. Your next step would be to take your twenty seven millimeter socket and loosen up the adjuster lock nut. And then rotate your crankshaft counterclockwise so you can watch the plunger inside the adjuster nut move in and out. The object to adjusting is have the plunger be level with the adjuster nut on the outside. And now it’s perfectly flush with the outside adjuster nut. After you get it sitting flush, you need to tighten back down the lock not using twenty seven millimeter. There is an o-ring inside of your crown nut that if it’s cracked or dry rotted any sorts damage you should replace it now. And then you’re going to want to put that back on. Grab your wrench. And tighten it up, make sure it’s snug. Give it a couple taps. Now that you’ve completed your cam chain adjustment, you’re ready to move on to your valve adjustment. Thank you for watching. Stay tuned for more episodes.

  1. No torque specks? really!
    So you just wing it by feel…
    How do you know that your not
    "to-tight" or "to-lose"…
    Their has to be a MFG torque speck, you expect an experienced person to do this totally by feel and not to damage his engine…
    Every MFG of any make and model always had a torque values for all fasteners and adjusters published in their service manuals…
