    Valve adjustment?

    I don't have one but can someone tell me the procedure for adjusting the valves on the new engine? A condensed version would be fine. Just wondering and haven't seen it published. Thanks much.

    I think you have to remove the cams to get at the shims (adjusting plates according to the parts breakdown), but that is guesswork from looking at the engine pics.

    Thumbs up Valve checks q 12k mi.

    Valve checks are every 12,000 mi. Here's a link to a google doc from advrider.com to the service schedule

    https://docs.google.com/file/d/0B9Dh...1zZWZLc3M/edit

    I'm not sure whether non-google users can access this though.

    Valves may well never have to be adjusted though because of the new design. The same seems to be true of the camhead GSs (08-12).

    And because it's fly by wire, there's no more throttle body adjustments!

    Remove valve cover. Measure. If out of spec calculate the needed change(s). Remove cam (that part is a guess) and remove current shim(s). Measure the shim(s) (maybe it's the marked size, maybe not -- assuming the shim is marked). Add in the calculated adjustment. Match that to the nearest standard size replacement shim. Buy (order) needed shims from your dealer. Replace old shim with new. Restore cam (assuming it was removed). Measure again to make sure you didn't screw up a calculation. Restore valve cover.

    Easy.

    Just like the valve adjustment on a flying brick 4 valve K bike.

    The Vulcan 1500/1600/1700/2000 have hydraulic lash and without drama.

    Good examples of how to do it, though they certainly don't spin like our engines.
    I haven't kept up with Kawi's developments; do their hydraulic valve trains live a long time?
    I've also expected Suzuki to come out with a good system, since they have a reputation of their bikes absorbing a beating and keeps on ticking.
    What do the big Yamaha Vees use?

    Quinton Grubbs did 260k miles on his 1500 nomad and I know another guy with a 2009 1700 voyager that has 175k miles. Lots of folks go over 100k miles with 1500/1600 nomads.

    Thanks, Kent! Now, do the followers slide sideways or does the cam have to be pulled...

    Usually the only time cams have to be removed is when it's a shim under bucket arrangement. My GPz750 had that. Pain in the ass. This setup doesn't look like shim under bucket.

    Curious about this also. I just bought one yesterday. Looking at the parts diagram, the followers ride on a pin rather that the tube from 2010 systems. Also the shims are not hemispherical but flat and seem to fit into a recess just above the valve keeper in the top of the valve retainer. They are several dollars cheaper than the previous shims and come in interesting sizes not even numbers. When I take delivery of the bike, I'll know more. I suspect the DVD is not out yet for service, that will be the go to place for information. The manager at my dealer shop has 53K miles on his and no valve adjustment has been needed yet. He said the adjustment was the same basic process as the cam head engine but his failure to know the shims were different leaves things open. Seems pretty stable though.
