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 The previous version was outdated and no longer supported.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

250-500cc Fixed cylinder crack didnt hold-

So i sent my cracked cr250 jug off to be welded and have the bore re plated-
Looked all good upon return-put her all back together with the new piston /rings,ect.
fired rite up, got her broke in,then went for a couple short rides(30 min or so)-
was washing the mud off afterward and noticed the crack came right back down the middle of the weld.! Damn- looks like i am the proud owner of a $300 paper weight! lol
Needless to say, im in the market for a CR/WR 250 jug that will go on my 2002 .
Not sure i want to bash on the shop that did the work-im thinkin they can use all the help they can get,with the work they do,-lol
 
Sux. I guess I know now that welding is not an option if it ever comes to that for me. But you would think that would work.
 
What caused the crack initially?? Is the frame cracked or bent? Do the mounts line up without being forced? Are all mounts tight? Is this type of crack a common occurrence on this particular model?

The last thing you want to do is wreck another cylinder.

So true!
Any chance of a pic? Maybe someone can give some advise how to weld it.
I did some cases recently and I'm very careful to make sure there is no stress on it before and after the weld.
Cleaning everything with acetone meticulously and preheating helps heaps in combination with choosing the correct rod.
If the crack is in the middle of the weld something went wrong, as mostly if it cracks again it's just next to the weld.
I would say the weld didn't penetrate enough.
 
Take it back to the shop and see if they warrantee it.

Any aly welding should pre heat and allow it to cool evenly after to avoid warping.
But yous all know that anyway..
 
yep,all mounts are good-frame isnt bent, as far as i know anyway- top motor mount has always been a bit tight on line up-but i dont think enough to crack it.
think ill check everything again and continue looking for a replacement- dont think i want to mess with tring to fix mine anymore- cut my losses and go forward.
i appreciate everyones input! you guys are tops!!:thumbsup:
 
If its the same guy search cracked 250 jug its a recent thread it was on the right hand side of cylinder and about 2" long through the water jacket looked like it started from the corner bolt going forward towards exhaust.
