440's necessary

I have a duncan national 440:
I have an fcr 39 mm carb:160 main, needle is in the middle,
I run lrd exchaust and I cut half the lenght off my lrd silencer.
I gained horsepower, I can go through 10,000 with power. It screams like a two stroke. Once I got it dynoed, My quad came alive.
I definately recommend a dyno.
