Well, unfortunately I have a few kilos more than before, so that the weight is probably the same as it used to be for two! :-)) Therefore the MBX should get a little more power. But because the engine is running really great, I don’t want to install a tuning cylinder. Have been browsing the forum and have already ordered a tuning ignition plate! What else would be recommended? Tuning membrane, 20,21 or 24 carburettor (which version?)? still a tuning exhaust lying around? TÜV doesn’t matter, was lucky and could the MBX still log on to my 07-oldtimer number! :-)) Can you help me? Thank you very much. Greetings Andreas PS: Since I used to have a black MB8, I am still looking for this. Who has one for sale?
