  • 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 The previous version was outdated and no longer supported.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 Piston pics.

What do the pictures say about the condition of my piston? Should I change pistonring, replace the piston or just ride? The piston have probably about 15-20hrs, mostly motocross (hard track). It runs well and is easy to start. It is a 144cc.

I med en ny kolv, den har börjat släppa förbi comp, därav det brända under ringen, vad kör du för olja och blandning.
Tycker du ska köra på 4% köp Aspen helsyntet helt sjukt bra olja, är ganska bilig desutom 98kr.

Looks well oiled in pretty good shape. Not new for sure, but okay.

You are getting a little blow by the ring so I would at least replace the ring if not the piston too.
 
First thing I would do is a compression test. Then if you feel it needs rings then you can at least check out the piston more closely when you have the cylinder off.
 
Looks OK but a compression test will tell you for sure. Any lack of power and change the ring at least. Replace the pipe o-ring as well. :thumbsup:

Why the pipe o-ring too?
 
STOP!

Never tear-down a dirty engine.
CAREFULY plug that hole and clean that thing off some. Same with the pipe. Make sure NOTHING falls into either hole. Or a piston will be the least of your worries.

Then- put the pipe back on and clean that motor.
Then- do a compression check.
Then- if nec., tear it down and inspect piston, ring and bore. If the piston/bore is beyond service limits it does no good to re-ring.

And yes- a new pipe o-ring is in order.

Happy wrenching! :cheers:

I was think the exact same thing. Never, ever....ever tear into a dirty bike.
 
hi, i know this is an old post now, but i was curious, how are you able to identify that the engine is blowing just from those images?

Iv just got myself a husky 125 sm and its covered 100,000 km on the clock but i dont know how many the actual piston has done, after a bit of research aparently a 2t psiton should be replaced near the 70k mark, is that correct?

I think im sufferning a bit of piston slap but i want to get a bit more knowledge on this before i clean strip and change the piston and rings.
sorry for being that annoying newb, guys.

Holy moly.....do you mean 100,000 m or 100,000km?...if so it is no surprise you have piston slap!

I replace the piston on my off-road bike every 1,000 km or so.

Okay, it is racing mileage but 100,000km is 60k miles or two trips around the earth and then some!
 
:D I was sitting here thinking the same thing. That's getting kinda 'long in the tooth' for a small block Chevy,....let alone a 125cc two stroke.
