• 4 Stroke Husqvarna Motorcycles Made In Italy - About 1989 to 2014
     TE = 4st Enduro & TC = 4st Cross

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 The previous version was outdated and no longer supported.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

2 stroke oil in 4 banger fuel

Husqvarna
Pro Class
A Husky/Yammy dealer told me that these bikes have 2 comp rings and an oil ring. The top comp ring can run a bit dry in the lube department and hasten ring and bore wear. This shop also races the bikes and they do the following.
Put in 50 mills of fully synthetic 2 stroke oil to every 10 litres of fuel.
This not only protects the bore and rings providing longer life it also helps cushion the valves and valve seats. The cushioning eliminates the need to use expensive valve addatives as well. Net net a good result. I honestly believe that my 06 TE 450 feels a tad smoother. I understand that Hondas and KTMs only have one comp ring and dont need this, however one ring set ups loose longevity V's 2 ring set ups I believe.

Give it a whirl and lets share your findings.

PS.Don't use 4 stroke oil as it really fouls the plugs very quickly-its not designed to burn as much as 2T oil.

Cheers.
 
Not on the bike bit I have been running 2T (mineral) in my Nissan Diesel for about a year now. 200ml to (a tank) 83lt.
 
I use Lucas upper cyl. lube. With the poor lubrication in todays fuel I would think this has to help greatly. I use it in all my bikes and my 4t snowmobile.
 
This is something that's been done by many for a long time, mainly in road racing. The hot set-up use to be a little bit of Castor based oil mixed into the fuel. Most modern synthetic 2T oils are an ester based, Castor like molecule anyway, so it's about the same.
 
But you gotta love that castor oil smell : )

I run Amsoil 2 stroke outboard oil in my gas tank for my 4 stroke bikes.
The outboard oil burns super clean as it is designed for outboards that do alot of slow trolling so it is engineered to resist plug fouling.

The Lucas stuff is good too but runs a little dirty.
 
I only run two stroke mix in my four strokes when red sticker season is over and I have to drain the two stroke bikes so they can sit, twiddling their thumbs for the summer. I don't reckon that I am hard enough on my four strokes to warrant a mix.
 
what about injection on the 08 09s? would it still spray properly through the injector?
 
Yes the ratio recommended is 50 mills per 10 litres. Its a good question about the efi bikes-does any one out there know if it works for them as well. Also note that the oil also helps with valve and valve seat wear so its a double whammy effect.
 
Marvel Mystery oil and 2 cycle oil, has been run for years though injectors. Search a bit and you'll find it's as controversial as 'what oil should I run'.

The ethanol content in pump gas may very well be a good reason to add a little 'upper cylinder lubricant'. 1oz per 5 gal, 640:1.
 
As lairpost pointed out, it's a somewhat controversial issue, like any oil question, but most run ratios of +200:1 and it seems to have no effect on EFI.
 
I run 25-30cc/1oz. to 2 gallons of Marvel Mystery Oil for my '08 TC 510 and '07 TC 450...been doing it for years with my Bergs, VOR's,etc....seems to work well.
 
Hey number cruncher you are pretty close, so check my math here.

I run it 300 to 1 which is 16.88 cc per gal.

Since there are 30 cc per oz.

that means that you would have to put in 2.813 ozs for 5 gallons of gas or 84.38 cc

Howz that for a bean counting response that you can sink your calculator into : )
