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 The previous version was outdated and no longer supported.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

Hi. i have trouble with main jets. Since i unlocked my stock exhaust. I changed my main jet from 142 to 150, but spark plug is very bright. If i change clip position from 3 to 4 i have problem with power to 1/4 throotle and spark plug is still very yellow/white (?) is should be more brown. What should i do? Buy bigger main jest like 155, 160? i cant change clip position because if i change it to more fuel, motorbike have problem to 1/4 throotle - it interputts.

Sorry for my english. I need your help.

Its Husqvarna SMS 125 2008 with Dellorto VHST 28 and unlocked stock exhaust.

hi Matuesz

this plug is showing a dangerous jetting that can damage the motor, for sure you need more fuel and a bigger jet is needed.

when changing to a bigger jet you might change your clip position back to 3 or even 2

I put main jet 160 + clip on 3 position but motorbike has problem in full throotle (looks like too much fuel - it interrputs, chookes

Now i have 155 + clip 3 and everything looks okay, no more problem in 1/4 throotle and full throotle. Its really good

This is how my spark plug looks:
Is this color good? Because motorbike drives really good. And i dont want to change anything.

If your motor is driving OK and responsive then you achieved the goal

the plug looks in my opinion still a bit on the lean side but it could be the monitor settings of my computer.

that plug looks exactly how mine does, I thought the yellowish tip only referred to a high lead content in the fuel but I'm not an expert, my bike runs brilliantly how it is set up. Though I've got a br8 ngk in, not a br9
