  • 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 The previous version was outdated and no longer supported.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!

I'm guessing it's the Cyl head O-rings. Are these a maintenance item? If not what should I do to stop this from happening again?
 
What do you mean smoking coolant? Where you in a tight single track and the bike started to boil over or riding flowing trail and started to boil over? Could smell it from the exhaust?
 
good call omg....where exactly is this thing smoking from? and no, the cylinder head oring is not a wear item, its just something just that is generally changed every time the head is removed. not something removed often...

Sorry I was almost fallong asleep when I posted this. It was coming out of the exhaust. I was in some tight stuff earlier but this has happened around 20 mins later after some pretty open trails.
 
Yep, inspect the o-ring and check the coolant level as it should be very low. O-rings are pretty cheap so replace it and worst case scenario is the water pump seal or possibly a base gasket...you'll have inspect one by one carefully but my money's on the head o-rings (do 125's run 2x oring seals?).
 
There's only a few places it could leak coolant into the exhaust. Head o-rings, base gasket, cracked cylinder or head. If the water pump seal leaks, it leaks into the transmission oil. Also, if you have the factory coolant in there, flush that crap out.
