I wanted to get on my rieju today, but when I had to cut off the cracker I had to find out that there is nothing in there at the cylinder outlet?!? The only thing I could see there was a kind of sleeve which but the outlet not greatly reduced. for me it looks more like the stop for the cracker so that I don’t clap it in front of the pistons. According to Tacho it runs at the time 65 km/h I think that the throttle was removed from the previous owner even though it is blushed. Then I pulled out the cat and drove off. In the acceleration it took a really big step forward, 🙂 Unfortunately I couldn’t test how fast she was driving, because it got too warm at 75 km/h the spark plug (NGK BR9ES) and the contact simply melted away Now I have built everything together again incl. Kat and will do the attempt again with a 90er nozzle. Can it lie on the too small nozzle that the Zü The following is what I wanted to change at the Rieju: 12 sprocket front (normal or extra hardened?) 48 sprocket rear (normal or extra hardened?) 90s nozzle in the carburetor New chain(must it be reinforced or is it a normal one?) Now I have the problem that there are probably different chain sizes. I don’t have a plan which I have to take. Is this dependent on the translation? I wanted to order the clamots here: http://www.zmg-motorspo rt.com/ and here: http://www.mopshop.de Can someone tell me which chain I have to order from ZMG for my Rieju at the translation given above? PS. I still need an address where I can order a clutch pulley and a 48 sprocket. I found nothing at ZMG or Mopshop. Thanks already in advance 🙂
