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 The previous version was outdated and no longer supported.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

Right my wre125 tried to spit me off today. a little history...........i have recently rebuilt the top end(less than 50 miles ago) with new ring/gaskets and o rings. I have been changing gear just before it gets into the rev band/on the pipe as it needs running in for about 50 miles or so (i was advised this by a Husky dealer).
Ok theres the history now onto today............I was riding home and the rear wheel locked up on me i pulled in the clutch and slowed down,when i let the clutch out again at just above walking pace it coughed and spluttered untill it came to a stop.After it had stopped i tried releasing the pressure in the fuel cap to see if it would start and it didn't. i then let it cool down( thinking it might of been heat seizure) and it still wouldn't start...called the breakdown people and after 2hrs i thought i'd try it again as it had lots of time to cool down and still nothing, it seems as though it has lost its compression.
So........my thoughts are either the auto lube isn't working and the cylinder has run dry or possibly the crank case gasket has gone....Any theories or sugestions would be greatly appreciated, or if this has happend to anyone else i would love to know the out come.
Cheers

Oh the joys!
 
Umm, you said something about the auto-lube quit working?? Are ya using mixed or straight gas?? Just wondering.............
 
Sorry what i meant was the auto lube might of failed and caused it, but since taking it apart i have seen oil on the underside ofthe piston and also in the bore, looking at the piston now its out i think it might be fuel mixture that's the cause......anyone care to agree?
 
That would indicate too lean on the jetting or an air leak.

Is the bike derestricted? If so did you change the slide too?

I;m not to sure Dave, it went like a stabbed rat! i can tell you that lol. i did change the carb for another 28mm mikuni from a aprillia rs turnuo
 
I once bolted a race pipe onto my rx50's derestricted exhaust without changing the carb, firstly the power nearly threw me off [I had only been riding a month!] , then the engine slowly lost compression and died, piston came out looking a lot like yours, maybe this page will help??http://www.smellofdeath.com/lloydy/piston_diag_guide.htm
Oh, and husky sport mechanic told me that you have to change the slide on wre's as well as changing the jets or you'll have lean seizure, though it might run great for a bit, hence your phrase,'' stabbed rat'' :D
