• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Just did my valves and the exhaust were a bit loose and the intake were fine. Would this be an indication of the bike running hot or something.
 
They seem to be set a bit loose from the factory, I tightened one up after about 1000 miles and haven't had to make a change since, around 11k miles now.

The valve clearance actually gets tighter as the valves mushroom and the valve seats wear, so you should be just fine.
 
You have a 610, am I right?
Although they say that the valve clearance should be the same on intake and exhaust valves, the dealer's mechanic told me to give a bit more play to the exhaust ones: about 0.08 mm instead of 0.05. In fact, they become hotter than the intake ones, because of the exhaust gas heat, and so they expand more.
However, I think that who decided 0.05 for every valve had his reasons and so I adjust them all using that value.
 
I agree with people who think that a bit looser, like 0.0025, it's ok, while it would be bad if they were tighter.
In fact, I try to do .05 mm, but obviously I can't be perfectly precise, so first of all I make sure that the .05 thickness gets through the gap and that the .10 one doesn't. Then, I consider that from the point in which the .10 doesn’t pass anymore to the point in which the .05 doesn’t, too, the screw rotates a perceptible amount of degrees. So I put the screw in the .05 position and then I leave it a bit rotaed towards the .10 position. I think that the result is approximately a .06 mm gap.
