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 The previous version was outdated and no longer supported.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

I run 40:1. I broke mine in with a tank of 32:1 and had so much spooge after a short ride, oil was running out the silencer and dripping on to the swing arm!
Even at 40:1 with the keihin there seemed to be more spooge than I would expect. I run my left kickers at 24:1 with virtually no spooge.
I was supposed to be trying my new Lectron out today but it's raining here so it will have to wait until tomorrow.

Who makes that skid plate? I like the pipe protector built on to the front!

i bought the bike used with 30 hours so i dont know who makes the skid plate but i will take pics and see who makes it and let you know. I think ill stick with 40:1 and be plenty safe after i adjust my lectron correctly ...
 
What mixture did the previous owner run? I make it a point to ask what mixture/oils were being run in a used bike before making too many changes.
 
The dealer I got it from had no idea thats why I'm worried about all of this. by the way I run klotz supertechniplate in my two strokes ( idk if that's how it's spelled)
 
The engine will definitely last longer at 32:1, but it must be jetted to do so. Many riders down here use 36:1.
 
Ty and I argue about this all the time. He runs 40-50:1, however, he has already had to fully rebuild both of his 2015 250 and 350's this year.

wow that a little excesive, i guess i cant go wrong to run 32:1 if im already going to mess with the carb
 
i also run super techniplate klotz, have forever. have also run 40:1 forever. i get good engine life out of stuff, but i dont race, just play ride but i dont take it all that easy on stuff. do you race? if i raced all season i would likely run 32:1...
dont forget ty davis is a mega fast racer.
on the other end of the spectrum i have a 88 xc250 that still has 215 psi compression that i bought as NOS. it has over 200 hours on the original bore. all its life has been 40:1, mostly klotz super tecniplate. before that golden spectro before i discovered castor.
if you have huge amounts of spooge, it likely isnt the premix, as the klotz i run has a very very high flashpoint of 460f, and i have little spooge issues, long as the exhaust isnt leaking. very little smoke, none once warm

you made me change my mind. Im like you , I don't race but I'm not easy on it. I have 40:1 in here now so I'll stick with it. I'll tune my lectron tommrow tommrow since the idle screw is only a half turn out.
 
hmm, half turn out from fully seated sounds like its rich, just guessing..
may the power of the castor be with you
 
I have always run some where between 32 to 35 to 1 BUT with straight 110 leaded race gas I have a 2006 Cr 125 that has more race miles then I believe any other 125 out there and it is still on the same stock cylinder and only 1 crank bearing and rod kit since 2006.
My current 2010 Husky 300 race bike went 4 years on the stock crank and is also on the same original cylinder
With race gas and the stock carb it does not spooge ever no matter where I ride it
 
I mix what the owner manual says, 2% synthetic (that is 50:1) and used 3% (32:1) for the brake-in period.
Most of the guys I ride with that have 2 strokes are using far less oil than me, some 1,5% (65:1), others even 1% (100:1), the guys that runs 1% are competing in the local and national enduros and they don't have problems as it seems...

I do like going that lean with the oil and prefer to stick with 2%. But my bike is smoking a lot and sometimes I'm thinking of lowering the premix a bit.
The problem is that we do some slow enduro over here, I rarely get over 1/3 throttle and the engine gets loaded up with oil and starts to smoke... I some open sections I do twist the throttle and the smoking get better after a few accelerations.

Well, thinking it, I think I'll let it as it is and continue smoking up the guys that goes behind me hehe

Regards.
