  • 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 The previous version was outdated and no longer supported.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 Bike won't start

Yep, carefully bend the little tab that contacts the needle. Make sure not to scar it because it can bind and cause sticking. A very small amount of bend make a big difference.
 
Turn the carb right side up and let the floats hang down. Then gently push them up and you will see where they push the needle valve closed between the floats. The metal tab that pushes against the needle valve can be bent to adjust the float height when closed. Sometimes I put the fuel line on and blow through it so I can tell exactly when it closes. It is spring loaded so after it closes you can still push the floats up some more, so you need to pay attention to when it closes off the flow.
 
Nope! Float adjustment didn't help.
It still don't want to start. Niether 40 nor 35 pilot.
May be it's not a carb issue?
Any other things I should check?
 
While kicking I realized that it kicks easier than it was when I fired it up for the first time. So I decided to check compression. It shows only 35 psi.
Where it can loose compression? Valves?
 
What oil and ratio are you using? did you break the bike in? no compression on 2stroke= rings or hole in piston:(

Yes, I did break it in. Oil Motul 800 2t 1:33 first tank and then 1:50.
Damn! I had never had this situation before just the regular piston and rings maintenance.
How could it be possible?
What Honda rings I can use? There are no husqvarna rings here for sure.
 
take the head off and have a look, check your reeds as well, 35psi is too low for worn rings.if you have lost part of a ring and the barrel is ok put a dab of grease on the counter weight rotate by hand and see if anything picks up on the grease if not you will have to strip or remove engine to clean out, you don't want any metal residue left behind.i bought a second hand 125 engine with excellent compression took the head off replaced the piston and rings and poured diesel in the crankcase and inverted.the old ring had a 2mm section missing.
 
Have a look what I have here!!! Just 10 hours, strange!!!

Should I order cylinder head with the rest of the damaged parts. Or will it work as it is?
Is counter weight damaged and should I replace it as well?

Thanks!
 
My guess is what ever kind of fuel your running it isn't good enough. It looks like detonation started on the hot part of the piston and broke the ring land.
 
remove engine, clean out crankcase check bearings run smooth otherwise split and renew bearings, head you could get re-machined, cylinder is a re-plate or replace job, piston is a mount behind the bar job and talk about over a beer job.
did you check piston was in right way round arrow to exhaust.
 
One of the option at the moment is to make it 300. 300 conversion kit is 200$ more than 250 cylinder assambly.
Is it worth it? Will be it absolutely another bike handling wise?

That's a very good suggestion, I was thinking of doing the same thing to my 250 when the time came for a re-plate of the cylinder.

All I can say about this orange bike is WOW!!! Of course it not even close to husky in power.
But handling!!! I was not even think that 4 stroke can be so good in this department. I can ride it faster than 125 at singltrack.
Defenatly it will stay in my garage.
