Default 07 yz450 no power hit

My 07 yz 450 feels too smooth and the power does not really hit. I came off a two stroke and miss the adrenaline rush of holding on for my life when the power hits. Is there a 07 450 I can get that hits hard with 5 gears. Or what can I do to make this bike hit harder down low. It has stock 13 front sprocket and I think a 50 on the back

The complete idea of a 4 stroke is to have smooth power delivery.
You could change the camshafts, pipe, gearing and have the head ported, but it will never have the hard hit of the 2 stroke.

It has a fmf system o ring mod. I have read that the old 03 ish yz450s were beasts and had been toned down in 06. What made these bikes so beast? is there a more modern beast? I loved my two stroke but it chugged gas and I used it for long trail rides.

The 03 was a beast, then they mellowed it out some for 04 and 05, and the 06 was an arm stretcher too. 06 cams and CDI should wake that 07 up. But keep in mind, it is a 4 stroke and can't come on the pipe like a 2 stroke, so if you are looking to give yourself a "holy ****!" moment twist the right grip further.
