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 The previous version was outdated and no longer supported.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

Where are you at for jetting with the stock carb? I will admit if there is one thing i really suck at...its gotta be carbs.

Mine is an 09 wr125.
 
in socal near the water the air here is fairly dense in spots. my starting baseline was

AS- stock w/ a tweak here or there
PJ- 32.5
N- #3
M- 460

too lean for sustained w/o with a small hitch on roll on from mid speed circuit to main circuit.

current-

AS- 1.5 -2 out
PJ- 32.5
N- #4
M- 480

oil- motul 710 2t 50:1, almost no smoke and little if any drool.

this works from 3000' to 6000' . it's clean and crisp enough in lock to lock ugly stuff and after long decents w/o being too lean for long open uphill stuff. hi dez i use 490 main, low dez 500 main.

ymmv

search "how a carburetor works" for a visual of the circuity...it's in the efi/carb section.

Awesome thanks so much. I've been searching all over for a good carb how to and it was here all along.

:applause:
 
Ok it seems to be getting close...I just have a bit of a stutter before it gets into the power valve. Im running Walts springs that open the PV at 6200 ish, and it feels almost like hitting a rev limiter until I crack the throttle open a bit more. This is between 1/8 and 1/4 throttle. I am going to go play with the air screw. But would what im describing be a rich or lean condition?

Im new to 2 strokes too....:D
 
1/8 - 1/4

how's your off idle response?

if it falls on it's face try 1/4 turn in on the AS to fatten it up.

then retry. if turning the screw in helps try raising the needle one tick to richen to make a smoother tranny from one circuit to another.

i dont know our baseline so im guessing here...
