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 The previous version was outdated and no longer supported.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

All 2st Namura Top End?

Hello Everyone. I am about to do a top end rebuild on my 09 wr125. I purchased the bike last year and this is my first Husky and first rebuild on it. I've come across the brand Namura. I have not heard off them. Their specs sound good and price seems reasonable but I was wondering who out there has used these piston kits and how they performed.
Thanks.
 
So I received my Namura top end rebuild kit. Looks like quality stuff. However, I have two holes stacked up and down on the exhaust side of piston skirt on my stock piston and no holes on the skirt of Namura piston. Should I be concerned?
 
I've read of this difference. I'm hoping someone can chime in... also me personally, I wouldnt be beyond putting the holes in myself depending on if that is all they are is holes and inside area of the piston is basically same as OE. Any good machine shop could do this or if you have an adequate drill press and some patience.
 
I've heard of seizures from pistons missing those lubrication points. I wouldn't want to take the gamble, personally I would drill the namura the same as the stocker.

Yes- drill these holes into your piston- otherwhise the piston will seize within minutes.
 
I'm thinking the seizure is what actually happened with my bike and the previous owner. I have no piston to reference as my bike didn't come with one.
 
Although there are no holes in the skirt, there are two holes underneath the wrist pin on each side on the bottom. I will say this about the kit. Everything looks high quality like I said before. Even comes with multiple base gaskets to adjust squish.

Here is where I went wrong. I didn't measure before I purchased. Tore it down. Looked pretty good. Seen the "A" on top so figured it just hadn't been used much so ordered standard 54mm bore without measuring. However, when I got to the point of putting new piston in cylinder I realized piston doesn't come close to touching the walls. Measure bore and its 58mm! Apparently its a 144! Feeling both embarrassed and excited. I planned on upgrading in two years anyways. Unsure who did it or if it was an OEM kit I contacted Eric Gorr of Forward Motion to evaluate cylinder and hook me up with top end kit I need and possibly port it for me.

So I can't give a full review of the Namura kit. But pretty excited about the 144. I hope Eric can get a little more out of it with porting so there's no mistaking its a 144.
 
Still interested to hear results. Namura is top notch. They are hypereutectic piston versus traditional cast or forged.

i heard some rumors eric gorr and forward motion are not working together anymore...

That could be. I assumed he was still there. I sent it there because they are only a few hours away from me. For the most part I only hear good things about them. Figured while they looked it over I would have it ported for low to mid power band.
