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 The previous version was outdated and no longer supported.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!

But they won't sell them unless you send them the cylinder head.
You got stainless valves from Bob?

I started loosing my adjustment quickly on "one" exhaust valve recently, seats/seat margins appeared to be ok but "valve" face was worn further into seat and noticed the valve keeper seat on valve was starting to round. I think I possibly saved my engine from major damage by looking really close to each part in valve train. I 'm going to have the seats done just to be safe...I know Ti valves are using beryllium seats and I can use my old springs and stainless uses different seats but also will need new springs, caps and retainers (most s/s kits are complete packages when you order them and price isn't far off from just the Ti valve, seats ,caps and retainer). I have about 355 hours on this engine and I too have replaced just the rings only once ! ..it will be getting a new Wossner piston kit during this rebuild. The crank/rod is still tight, the cylinder is still in spec for roundness but loosing some of cross-hatch marks. I LOVE THIS LITTLE 2010 TC !!! ...of course I love my '07 WR125 too ,but just some minor suspension set up, that TC is my" DO ALL" bike

What's with that Wossner piston kit?
If no one else, I'd like to see the work you do with the valve job ...I'm pretty clueless on your words above
but I do not want a head exploding on me, so I gotta bite that bulllet ..Hope I'm not over the question quota limit, but I stay off the REV limiter and probably stay under 10K RPMs ... Can you say the same thing about your riding?

Mine is a do-all bike also ... I just found about the most awesome mountain uphill road I've ever ridden (that I can remember) and the bike is all I want for that ~thrill or attempt at getting ~75% of what the bike is capable of delivering .. I'll be taking the same bike to our local sx type track this week ... And yes, the bike is not perfect, same as it's owner ... But it's all I want and I am not looking for anything else someone might call better ...

I would say first is to keep a good record of any service work you have done that way if things don't start looking right you've got some history . If you start noticing your valves needing to be adjusted every interval you set up to check them, something is going on...this is were logging your info becomes valuable. If they are moving(clearance changing) but aren't enough to shim to get in spec, they are probably ok.
Doing / replacing valves in the Husky is fairly easy , but before tearing into any engine I do a leak down test - get some idea if the valve is leaking thru the seat area....if there is, time to check head/valve train (there is also a dye you can use to check seat sealing but I never used it)
I was told years ago that you NEVER lap Ti valves to seat them ,so that's when you need a good machine shop to cut the seats to match. Also, I never reuse valve retainer clips ,caps or valve guide seals when I do my new valves.
I wish I could be more help...never dawned on me to record/photograph my teardown. I could try and take some pics of the valve and keepers to show the wear and the valve seat wear.
Oh yeah, Wossner....exceptional wear and slight bump in compression. Used them in my 410 and 570....I road my TE 410 on the street and trails and a year of enduro's ....I bought it for cheap because it was an oil burner-freshened up the top end w/the Wossner ,had it for 5 years and sold it to my nephew who still rides today ...about 16 years on that same piston!
