Vintage Two Strokes / Re: Can you name the bike??

« on: January 23, 2010, 06:13:18 AM »

The cylinder looks vaguely Husqvarna, but nothing else does.  The frame looks a little like an '81 Maico, but not enough.  This must be one of them there strange European bikes we don't get out here very often.  There are a lot of vintage brands that are fairly common on the East Coast (not to mention Europe itself!) that we don't see here on the West.

ANYBODY else?

chain saw pro? how do you become a professional chain saw-er?

We Canadians say Chainsawpro for the timber guys who are out there and,...you know ....
In the early 70s when SACHS-Hercules was importet into Canada,as a sideline they importet SACHS DOLMAR chainsaws.
To brake into our market the saws where given to the timber pros for very little money.
Because the winter time was quiet time for the motorcycle business,Horst Kempter,Prez of SACHS Canada,ask me to visit the timber camps in the east to see how our saws worked.
A team of two would be working up to 8 hours a day,walking on frozen ground where in the summer would be swamp.Biggest complaint weas,inhaling the fumes of the exhaus coming out in frond of the saw,inhaling very cold winter air,getting sometimes dissy,....
So we started experimention with a flexible exhaust pipe fsatened to a harness on the shoulder.
But was not practical to disconnect when the saw was running empty and was handed over to the helper for filling and sharpening.
So we wend with one of our Pro saws to the then still existing PIONEER chainsaw company in Peterborough.They had a kind of a dyno test bunker to set up there saws for the world champion ship.
Here we mounted our saw and fed her with our SACHS saw oil(yes you get it) OPTI 2 oil.
Over a period of hours we leant the mix out from starting with a 100-1 and decreasing it steadyly until we had reached 300-1.With that mix we run the saw 10 hours non stop.After that we took the saw apart and where amased that absolutely no wear was to be found.We could not convince the timber people to use 300-1 but got them to use at least the 100-1.

Interesting also the story how the oil was original developed.

   Politics-Religion-Oilmix,.....we will never come to a common agreement
Its just not possible.
We have discussed it for many years,probably since engines are in the world.
It will never change.
But here a nice story out of my expirience.
ISDT Germany 1962.I am a team member for Germany.
My bike DKW 175 cc.Gas from ,oil from Castrol.Mix 20-1.(that was a common mix in this days).
Optimol Oil Werke,from Munich(just around the corner from Garmisch Partenkirchen),comes (for the very first time in Offroad competition) and makes us(our team) an offer.
They sponsor us with gas and oil mix.If we finish the ISDT we get a nice lump sum of money.(we all where hungry amateurs).
If we got a Silver or Goldmedall we would get even a lot more money and maybe a contract for the following season.
So whats the catch we where asking.
Well the mix will be 50-1.(oh shi......)
If we would have a oil related failure,we would get a brand new motorcycle of the same model.
After a team member meeting and discussion we decided to go for it.
All bikes got filled with there mix and we wend out for carb testing and tuning.After done that,we made a full power test in the mountins(ALPS).There was one thing right away we realised,the bikes startet very easy,had a crisp and healthy sound,and did not smoke.
Result after 6 days we all finished and I had my very first GOLD.
In 1967 I moved to Canada and in1970 a Canadian friend and distributor visited me in my shop to show me this new oil he was interestet to import,but,,,,he wantet me to test  my bike first,...because it has to be mixed 100-1.Yes it was OPTIMOL oil.It was a little shock because even now we where using oil mixes 50-1 but 100-1.???Well it worked and I never looked back.
Most important.Carb.set up.Constant gasoline and oil mix with the same make.

Work of art that front end.

I think it was Roger de Coster.It was a interesting project by Honda just like the OVAL piston.But it never came trough.

Hello John.
I read your beginning and I agree totally with you.
Being a member on several foren around the world(on which I often help with information I have collected over the 50+ years of racing and over 35 years running a dealership.)I have seen some bad moufhing people.The only way to beat them is given them one warning and ban them for good at a second time.
Life can be great,and we can make it interesting for sure without idiots.
Keep on doing what you started.
Cheers...

Lectron is the older company and the carbs cost less.

In January 1977 at the Toronto MC show,I had my stand right beside the LECTRON stand.
The rep for Lectron at that time was Kenny Roberts.We where sitting for 4 days together and he explaint to me the function of this unic carb.I did know about the carb because John Penton offered with his Penton bikes the stock BING or the Optional Lectron carb.But had no expirence with them.All I did know was that the standard BINGS on all our Zuendapps-Hercules-DKW-Maicos-Pentons,would only work when brand new,but had to be adjustet when a HORSE nearby farted.
On the end of the show,I handed Kenny a check for 10.000 Cad $ and he made me the very first importer distributor for Lectron.
And he gave me the CUTAWAY Lectron carb he had at the show.
I still have that carb in my office.

Then you can put this carb on it :  http://www.cpcracing.com/site/256083/page/190735
$550 is a lot of cash though.

I would say that this is a very close copy of this:

OPTI-2  100-1 on all my modern and Vintage 2 strokers.
OPTI-4 in all my modern KTMs 4 strokers.

(its the same oil almost every chainsaw pro is using.)
Maico was using it under there own Name MAICO RACING oil 100-1.

The German Munich oil company was sold several years ago to Castrol.
But a sister company bought the license early enough and is making the oil in the USA.

Would a TZ250 engine be legal in a YZ250 frame? Would you ride it?
It would be cool if someone stuffed one in a YZ250 though.

Somebody in Germany is racing this 250 twin ADLER with very good results,but he admits that it took him a long time to get used to the uprupt powerband.

Vintage Two Strokes / Re: My old dirty mags!

« on: January 22, 2010, 12:36:44 PM »

Talking about collecting mags.



In each of this old OPTI oil boxes are 2 sets of 25 issus German Mags " DAS MOTORRAD"

beginning with the early 60s up to about 2007 ( I believe.)

I had already a good collection,when I got a call from an older German Gentleman who tought he would nt make it to the next year,had no family and wantet me to take over his collection.
When I came to his place,I was glad that I took the VAN (empty) and not my wifes Toyota Prius.
And a nice printed list with almost all teststories and in what year and # issue to find.
I think I figured one day that it is a total of 13000 mags.
Somebody speaks GERMAN?
No they are not for sale,but interesting to reed.Funny the old test storys from the 60s.
