ZDZ Service? ZDZ 100 Inline Twin
 

Hi Folks

I recently bought the new version of the 100 cc inline twin, directly from ZDZ. Now that I am planning my exhaust system, Krumscheid in Germany told me that particularly ZDZ inline twins need two seperate exhaust systems, or at least seperate manifolds for each cylinder leading to a 2 in 1 muffler. Apparently those engines have the problem that exhaust gases from the first cylinder get pushed into the second cylinder which is obviously not good. This problem does only seem to apply toZDZ engines, I heard.

Now the easiest way to find out would be to contact the manufacturer. But my calls and emails have been unsanswered for over a week. Does anybody know if this particular problem does still persist with the newer versions of the engine?

Thanks
