Hi Lumpy,
Yes indeed, there is a bike called a Junak, it's 350cc and quite a lot of them clatter about here leaving a trail of smoke, oil and engine parts in their wake. More than you ever wanted to know is on this site
http://www.junak.net and google translate works well enough. I completely agree that scooping one up now is the way to go, fully restored examples are beginning to emerge, as are shows,rallies etc. They can look very smart and were an impossible dream for most people in their day.
Happy to find out more but probably good to move the posts to random ramblings thread as a Junak is about as far as it is possible to get from a perfectly restored 75 900ss as it is possible to get...(except for the trail of smoke,oil and engine parts bit)....
Cheers
In-Two
