Assalamualaikum brothers!
I was interested to swap the engine from cg to something more powerful but i Don't have knowledge and that much money, so i decided to get the stock engine to its limits
I don't have any knowledge regarding engines but heard about some parts and their working
So i want to know what is best for cg
1: which spark plug is best?
2: which exhaust is best?
3: which is the best CDI to maximize rpm?
4: which chain should i get?
