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 The previous version was outdated and no longer supported.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

125-200cc Husqvarna WR 125 (144cc) 2004 problems and questions

Hi! First time writing here. I'm from Finland so please keep that in mind when recommending places or shops. Sorry for the messy writing...

I have had this bike for a quite a while. More hours fixing it than riding it. Not going to write a full history, since thinking for the right terms would take a whole lot of hours.

2014 I sent the cylinder + head to Eric Gorr who was then doing business with Forward Motion. He (or whoever) bored it to 144cc and machined the head. I have read bunch of things about him later. Had no problems getting the big bore set.

Some years later I opened the whole motor and did the bearings, clutch etc. At this point the 144cc kit was still new and not used. Assembled the whole motor and got it running. Not many hours later I felt the cylinder pressure wasn't as high as it was before. Opened the head and noticed some scratches on the cylinder wall.

Immediately thought not going to run the bike before further inspections. Few years later, again thinking if I should do something about it.

So yeah. The question is, where should I send the cylinder for coating and where should I buy a new piston. Any ideas for Europe? I once sent a 125cc sylinder to Holland (if I recall right) and it was okay.

I do have some ideas but this time trying to do as much research as possible.

I also had some problems with the clutch after assembling the motor but will tell about it later.

What sort of drop in compression ? Did you check the squish after rebuild? What thickness base gasket did you use? I t doesnt look all that bad . I would keep running it .
 
I would run a ball hone in it, and that will show you where the coating has worn through. The aluminum will look starkly different than the coating after a few passes. I bet that bridge area will look like all aluminum. If it looks the same as the rest of the barrel after alight flex hone, then I would run it. If not....no.

You sure about ball honing a ported cylinder??

Cant imagine that wouldnt beat up the transfer ports, and my understanding is you cant hone nikasil anyway?

I have never had any problems with plated cylinders in the last 40 years. I think you give little aluminum oxide berries on springy stems a little too much credit. It will only take 4 or 5 back and forth passes to give the cylinder wall a very nice finish.
