the video is for bucket and shim type valves on a twin cam motor with cams above the valve/bucket single contact patch/wear point.
the xt is single cam so uses a rocker and follower two contact patches/wear points setup with the cam lobes up for opening the valves lobe down for valve closed.
no shiming on the xt motor its lock nut and adjustment screw as per erlier in this thread which is 5 yrs old btw.

Talking

I stand corrected but what I know about XT's can sit on a microdot! I'm a GS man and we have shims

But it is massively appreciated! I cannot open the site, but I guess it's a temporary issue. Looking forward to check it out!

Do you have any recommendations for a home-made tool to rotate the square adjusters? I use a pair of pliers but it's clumsy and makes getting a consistent 'feel' for the gauge difficult. Good spot on the angled feeler gauges. I use an old set that I have creased into the approximately right angles, but the ones you have seem ideal.

Good post, thank you.

IMPORTANT. Don't get the one I've got, this one:



Why? Too big to work in such a tiny space, since you have to put the wrench right under this tool to tighten the locknut, while this tool must remain to top to hold the adjuster at the right position.

While something like this (that I'm going to buy to "re-adjust" again the valve clearance) may allow you to move more freely, more precisely while the wrench remains underneath. You should be able to lift the box/ring wrench to keep on tightening the nut while you still keep in place this tool to maintain the position of the valve adjuster.



I'm no expert, but the opposite, that's why I tell you, don't try the big one!

Thanks guys - that looks perfect.

Update: I've been looking at offset feeler gauges on eBay. I can't find one with less than .005"/0.127mm blades. The inlets need .004"/0.10mm at the most. Think I will stick with my home-modified Halfords cheapies for now. The Motion Pro gauges are over 30GBP per blade - that's way too much for a bit of convenience, even though they look very good bits of kit.

Membership - help keep us going!

Horizons Unlimited is not a big multi-national company, just two people who love motorcycle travel and have grown what started as a hobby in 1997 into a full time job (usually 8-10 hours per day and 7 days a week) and a labour of love. To keep it going and a roof over our heads, we run events all over the world with the help of volunteers; we sell inspirational and informative DVDs; we have a few selected advertisers; and we make a small amount from memberships.

You don't have to be a Member to come to an HU meeting, access the website, or ask questions on the HUBB. What you get for your membership contribution is our sincere gratitude, good karma and knowing that you're helping to keep the motorcycle travel dream alive. Contributing Members and Gold Members do get additional features on the HUBB. Here's a list of all the Member benefits on the HUBB.
