    Hey nice 450 man. I just bought a 04 YZ450f yesterday for $1800 from a guy that basically bought it new and never rode it. Still originally frame paint everything. If you seen a picture you wouldn't believe the shape of it for $1800. I'm a 2 stroke rider by heart but I'm not gonna like I'm loving this 450. My 01 YZ125, and 99 KX250 both top out at 70 max where the 450 will go close to 100. There's no competition there haha. Keep on riding brother!

      That’s awesome! Some day I’d like to find 99 kx250 to restore. My dad had one when I was a kid. I always thought that bike was so cool with the green frame.

      *Blu Gods* yeah! I’ve started it and let it sit and warm up and rev it up a bit just to get it warm. Not any issues. But put the fmf on and took out to listen to the difference. Same thing I’ve done with stock pipe. And it got warm enough to hear coolant boiling and out the overflow.
