Royal Enfield — Classic 350 getting rust

Address:

Kozhikode, Kerala, 673631

I purchased a classic 350 one month back. I done the first service. Few days later i noticed a rust in the spark plug near engine. I am worried about spreading the rust. The srevice people told me that it wont get affected. But the bike is only one month old and iam worried about the present situation and it might get worse. I wanted to get the problem resolved at the earliest by your service centre nearest.
