• Husqvarna Motorcycles Made In Sweden - About 1988 and older

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 The previous version was outdated and no longer supported.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

Ah! Tm's had injection pumps and bottle behind the side panel.
To take mine off, I made a cover plate for pump behind shifter. Plugged up the injection holes and had to drill hole down to bearing on ignition side for lubrication.

Buddy did everything except the hole and took out the crank bearing on ignition side. It also spun in the case so he he had a weeble that wobbled.

Anyone whom owned a Tm always bend shift shafts as soon as chain came off. Notorious for also busting the ignition case, if you didn't cut the ears off.

Think oil injection tank was a pint. You had side plate window to look through to see if you getting low.

They called it CCI auto lube.

Beta's new Xtrainer has oil injection and a dash mounted warning light for when the oil gets low. I would welcome oil injection on all 2 strokes. EZ and you go through WAY less oil.
 
Most youngsters have no clue what a ratio cup is? I see them mixing by color. Then I educate them. But I can't teach them all. I've seen engines run so hot and crank bearings expand to the point the flywheel hits the stator ripping it off the case. I can shake the bearing the play is that bad. The gas was clear no oil. When the engine cooled off there was no play in the bearing. He ran the bike on straight gas.

Then there's the other kid who kills every insect for acres. His mix is 5:1.
He goes by color but it's darker.

I welcome oil injection, fuel injection and e start. Bring on the big bore street legal 2t bikes. I'll buy one right away. I have some nice country dirt roads to ride.
 
My first bike was a Kawasaki KD100 that I bought new with hard earned lawn mowing and snow shoveling money. The oil injector quit and it seized before I could wear out the factory tires. In the last 39 years I've never owned another oil injected 2 stroke and I've never forgot to mix my fuel.... an injector pump can't fail if it doesn't have one.

I had a ke100 and ran it out of oil. I got some oil and continued on my way, some walking involved. Seemed like no harm though it just quit about 10 miles later, never did repair it. Oil injection should come with a low oil shut down feature or at least an idiot light. Pre mix well running out of oil is just like forgetting to turn the gasoline on.

Mine never ran low or out of oil, it just quit pumping it into the engine. I usually favor less complicated for more reliability and less weight but oddly I like the concept of direct injected 2 strokes, probably because of the massive gain in power making the risk rewarding.

There is also the situation where someone forgets to mix gas and boom. Id say that might be a more common issue. Seen it more than once myself. Saw a KX250 go 12 miles or really gnarly stuff with straight gas before locking up. I have never seen a motor so destroyed. Piston was literally part of the cylinder and had to be cut and beat off the bike. Was crazy looking.
 
Can-Am's had oil injection and they were the fastest bikes in their displacement class for many years. The pumps weight very little, the quart of oil to supply the pump weighs more than the pump.

Statistically you are many times more likely to forget to mix your oil than you are having an oil injection system failing.
 
It seems to me that there is an advantage to oil injection since it can deliver less oil at small throttle openings and progressively more oil at larger throttle openings. Some of us started out on two strokes when the common ratio was 20:1, but as oils have advanced, the ratios have changed. I run 40:1 on my bikes today, some run 50:1 and so on. Now here is my question, because I genuinely don't know the answer. If I had a vintage bike with oil injection, how would I adjust it for modern oils? Likewise if it is modified for higher RPMS, I may need a higher concentration of oil to compensate for how much I'm blowing out the exhaust. The factory adjustment would be for how the machine was originally designed and the oils it was designed for. So, would it be trial and error (seizure)? :excuseme:

dump it in, ride bike. Its way better than what was run in it before.

A friend of mine is trying to get me to use Amsoil for my pre-mix at 100-1. anybody have experience with oil, and if so what results?

100:1 is fine and commonly done on trials bikes that idle a lot and only have short bursts at high rpm. I would mix closer to 40:1 for motocross or other riding that involves having the throttle wide open for longer periods.

the oil is lube for the crank bearings, rod, piston cylinder rings etc. Running less will mean less lube for those parts. IT will also make less power as the oil helps the rings seal and reduces friction. It will work but is not ideal IMHO.

You really need to specify which amzoil produce. I know the sabre pro has 100 to one on the front of the bottle but not quite so bold on the back if I recall.

I use the sabre pro which is more for chainsaws and other similar devices. I mix it at somewhere between 2.6 and 3.0 fluid ounces per 128 ounce gallon. I have noticed the ktm 200 new ones are stating 60 to one maybe the other new two strokes Husky included are doing so as well.

Actually I have a ktm 200 2004 model and there is a page or so in the manual pertaining to the oil injection system. Of course that system was never on the models sent to this country. Factor that into what is best discussion. The dual sport Italian 125 (Husqvarna) never imported here had injection (and a wide ratio transmission by my standards) but it is often recommended on internet discussion forums to do pre mix for reliability.
 
I have the Yamaha TY 175. Under strong advisement, I have been told to use only oils made for injectors. Some premix oils may be too thick to pump through small oil lines. More likely when cold. I had an outboard motor with oil injection. I would put just a little oil in the gas tank to make me feel better. I know some people that have tried to use outboard injector oil for premix with bad results. Not made for that kind of RPM. Just another thought for the mix. Jeff
