I purchased Honda CB Shine 125 cc, When I start directly it not start, when I used choke and start bike it start and I on the choke for 10 to 15 secs(The choke case is always happen in morning time in a day). After a year still this process is running. Few times choke I didn't used, but every day I have to used it. Is it compulsory for bike to start it first time with choke?

And What is the benefit of using choke.
