Hello men! I have a Dax ST 50 in org. Condition from 1977. Unfortunately I am not satisfied with the driving performance at all, since I also weigh 85kg. Now I intend to install a 72cm3 cylinder with “49” inscription and other carburettors to make the thing halfway mobile. It should not be more remodeling, since I absolutely want to get the Org. Condition. Here I have the following concerns: 1. Is there also something reasonable of Takegawa or similar? (or Ratiopharm) 2. Should it be an aluminium cylinder, or is it enough for a grey cast? 3. Are there then temperature problems? 4. Can the org. oil pump remain in it? 5. Which carburetor in which size should I buy? (restrictedly with an integrated petrol tap and good quality) 6. Are these replica carburetors working well and can be adjusted? 7. Can I continue to use the old suction nozzle? 8. Does the oil consumption increase? 9. Is it even recommended to convert the stuff – cost / benefit? Who knows about it and can brew Give some answers and tips? Ask for help!!! Until then cardboard spoons
