Question about 1989 Aprilia AF1 125 Sintesi
Hi all ive just got a 92 AF1 125 and on checking it over have found that the trottle cable splits into 2 one goes to the carb but cant see where the other goes. Is it for the 2 stroke ?
Congratulations. You have just purchased a very high performance 2 stroke 125cc from a very talented Italian manufacturer. A two stroke engine needs 2T oil to be mixed with the fuel before it is fed into the engine. This is a cumbersome job and one has to get the ratio just right. So in order to make the job easier you have two tanks. 1) The regular fuel tank & 2) A small capacity 2T oil tank (made of plastic mostly) which is hidden behind a side panel. In order to give a regular dose of 2T oil there is a tiny oil pump attached to the side of the engine. This oil pump has to be actuated simultaneously when the carb slide is actuated. Hence the banjo. So now you know why the throttle cable splits into 2. One goes to the carburator and other to the oil pump. Good luck and enjoy your bike sensibly.,,,
