I have a 2007 CRF450R.
I live in the Pacific Northwest at an altitude of around 2000 ft.
The bike has a removed backfire screen
Two Brothers carbon fiber exhaust/SS Header.
The bike runs great. No bog, no hesitation. Very slight if any "popping" on decel.
My question is, would the JD jet kit add any noticeable performance to my bike? I know that the multi-tapered needles are said to add performance, I just wanted to know if it was noticeable/worth purchasing.
I have installed a JD jet kit on a 1999 YZ400f (my brothers) and felt noticeable improvements. However, his bike was running like dog crap before.
Thanks
