lower point = bad thing about ES.. i think thats what he meant lol not sure myself

btw welcome kinwei 

Where got hard to find NOB1 triovale? a brand new one cost around RM180 if im not mistaken. The one with black coloured muffler.

that one is NOB1 Triovale exhaust rite?
you're using it ar? 

That bike shop we went last time. Bee Hock Motor. If you can get cheaper labour charge for sprocket, go for it
It's not exactly backfiring. It is due to very hot temperature of the exhaust pipe. It happens to me when I changed to NOB1 SSS with removed air filter.
Why the temperature is HOT?

It's because too much air going into the engine, with limited fuel. So the air/fuel mixture is slightly lean. Lean mixture will have more complete combustion, hence the engine will turn hotter. If the mixture is too lean, there are a lot of explosion sound from exhaust. This 1 gotta jaga, sure the piston will go bonker.

I guess you will encounter pom pom when going more than 3/4 throttle. You rejet your carb to mainjet #107.5 and see how? If still pom pom, try to move the needle position up by 1 tick (the stock needle position is at the middle, move the clip 1 tick down).

150km for ur 1st service??? Is it too early??? I thought the 1st times is around 500km.... So charge tomolo 11am meet at Bee Hock right?? Btw how much??
