  • 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 The previous version was outdated and no longer supported.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 will start at the beginning. This bike has been in my family from 98. It became mine about 6 years ago. I never had any problems with it. It was used as a backup bike. My godson was riding it this year and it lost compression. So when I took the head off I was amazed that the top of the piston was super clean with just a tiny bit of carbon on it. So I thought the head Oring was leaking a tiny bit and steam cleaning the piston. So I put a new piston in and new head and cylinder O rings in it. I start breaking it in over two days by running 3 minutes. Both times ran great. The third day I go to start it and I can hear water sloshing as I kick it. So I take the cylinder off again and see the crankcase is full of antifreeze! What could of cause this?? Any help would be appreciated.
 
a leak HAHA IM NOT FAMILIAR WITH THE COOLANT ROUTING ON THAT BIKE BUT MY FIRST GUESS IS THE BASE GASKET
 
I put a new base gasket in when I did the top end. When I took the cylinder off the base gasket looked fine. What I don't under stand is it ran twice fine. Then it filled it self up.....
 
coolant in the crankcase can enter through the cylinder, cylinder head or their gaskets. There may be a coolant passage through the case halves but that's unlikely to be the problem because it hasn't been disturbed (unless it's been corroded by poor coolant)

You mentioned it lost compression - why? There may be a clue here as to what the problem is. A head gasket leak bad enough to give a massive compression loss would have blown coolant out the radiator and left a very obvious witness mark.

You may have a porous or cracked cylinder or cylinder head.

Inspect all components carefully and thoroughly, I'm sure you'll find the problem mate.
 
My guess, you have a center case coolant passage leaking, something warped, cracked, rotted through, etc....

Also, had one that did that. The studs/nuts dragged as I torqued everything.
Torque wrench clicked as being like 20 foot lbs, but nut was not drawn down tight. The nut was dragging on the stud.
So make sure all your fasteners are wire wheeled, cleaned up with die or tap, etc...
I always squirt lil WD 40 on my stuff/and or anti seize, that I don't loctite, to get accurate torque readings.
For life of me couldnt figure why base gasket was leaking and nothing was warped, cracked, gouged, scratched etc...

I always scuff gasket surfaces with scotch Brite pad for grip and never use gasket glue or anything on surfaces. Then wipe all surfaces with rag and carb cleaner, to make sure nothing was oily. Look at your base gasket to make sure it wasn't sucked in or blown out a lil.
 
your engine is a typical LC modern engine
it uses O-rings to seal the top and hoses to transfer the coolant
the cylinder and head are the only items that see fluid
your issue is either O-ring or a casting issue of the head or cylinder
 
George, that was where I was going to look into next. If the water pump O rings where leaking. If they are leaking would it also mean the main seal was leaking and the antifreeze was getting in that way?
