Alan R.: Exactly! There you have all three og the Taifun models. I have the military one. Pictures of my bike can be seen here: http://www.tempo-online.net/phpBB2/view ... =38&t=8458 .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Phil A.: Did that happen to 2 strokes as well as 4 strokes? The big end bearing in this Sachs engine is a roller bearing. .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Well, I will find out soon enough, when I get the time to take the cylinder off. Thanks again to all that have shared their experience and knowledge here. I will report back! .-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

I used to know an ANDERS MICHANECK-----Captain of Reading Racers Speedway back in the early '70's. Are you related by any chance ????????????

Michaneck.... No, never heard of him. He is a "mechanick" I suppose....? .-.-.-.-.-.-.-.-.-

My first name, Anders, is fairly common here in Norway. Almost 20000 of us (out of about 2,5 million). My family name, however, is not common at all: Only 3 in Norway, and probably in the world, having "Rudnå" as their family name. My parents made it up in 1960. .-.-.-.-.-.-.-.-.-

Anders -
I'd be very interested to learn what you find when you eventually strip your engine.
My own experience with bike engines that have spent a long time unused is that they can, and do rust internally owing to condensation, to a greater or lesser extent depending on storage conditions. If the engine has ball journal main bearings, these can start to rumble within 500-1500 or so, and if ignored can fail completely. (If they pass this mileage without problems, then you're probably OK.)
If you're unlucky, this condensation and rust can also attack a roller big-end bearing, and possibly other bearings in the crankcase. I am myself presently rebuilding the engine of a Honda single (with minimal mileage) that developed rumbly mains very soon after being freed from 6 year's storage in a damp shed.
I haven't as yet ever come across a failed plain small-end bearing or stuck rings as a result of long-term non-use.....maybe I've been lucky.

Hello again! Yesterday I finally had the time to dismantle the top and cylinder to investigate this matter further. (There has been a winter inbetween, and the bike has been stored.) Here is the diagnosis: The small end bearing is worn out. Fortunately this is one of the easiest things to cure. Even if a new bronze bearing should not be available it is "piece of cake" to make a new one, as my father as a well equipped workshop incl. a lathe and everything needed. And maybe I need to make a tool to extract the old bushing and insert the new one. But that too is easy. I will be back with a final update as soon as the engine is back together again. Regards, Anders F. R.

Do I win the prize?! Diagnosing mechanical problems from the outside of an engine is never easy and I can't seem to do it on my own bikes so I will feel cheered up for both of us! Good luck with it Anders,

Mark M: If not a big prize, at least you have deserved "Honourable mention!" ..... but you have to share it with Les H., that also pointed out the correct answer. Thank you, all of you! Once again I have got the answers I needed here and learned even more about engines. Regards, Anders F. R.

Anders, I was going to name check Les but he had it as suggestion no.2 where I staked everything on one reply which is why I was pleased to have got something right at last!!! Hope all is well with you Anders, and Les too! Lovely day here, have to ride themodern today but still, anything is better than nothing!
