As you park your bike at night the silencer gets cold and the water condense inside your silencer. So when you start your bike the next day it will spit out water vapors. Abhi silencer NAYA hai thats why there is no carbon deposits inside it. Jaisay jaisay bike chalay gee carbon deposits will line your whole silencer and then you wont see any water dripping out as it will absorb the water vapors at night. Kuch din kay mazay hain....kerlo show-off
Waisay thhe engine also produces water.....but this water is in steam form. Basically the catalytic converter (jaali) inside your exhaust turns the hydrocarbons fumes into CO2 (carbon dioxide) and H2O (water). If it were 100% efficient then each litre of petrol would result in one litre of water... As Euro-II CG125 has a bigger catalytic converter than older models thus dripping water in cold starts will be a little more noticeable.
So yeah you're worrying about something that all bike do when they are new.
