I had a pretty quick stock bore yfz450 but got rid of it.
Now i built my girl a stock bore and stroke yfz with a 06 lowerend and 1+ head the chassis is pretty light so we will see how it does.

I am in the process of building me a drag 660r raptor but wont be a while until it is done.

My buddy has a 815cc ds650 and moves out pretty well, and will have some juice on it pretty soon.

The first yfz i built i had Jeff @ FAST racing port it and it was pretty quick for a stock bore and stroke.

Neils as in Velocity racing?
This need +1 head is done by T-rex my buddy that lives in Texas and with this new setup it should run alot harder than my old yfz i built, but we will see next weekend.

Ya he had some good work done, if i remeber correctly nil's was having Mixxer port his head, but i am not 100% sure on that.

I got one of the 1st 15-1 pistons that came out and oh boy did it run.

Nils had nothing to do with Airforce one, that was a nmotion build.

i think someone would have to ask terry on who actually "built" and designed that motor.. or rocky might know?

tims ds is a fast dude now..

steve's raptor is super quick also..

both have a LOT of money in them and after building/ seeing/ contributing the raptor 700 i wouldnt dump money in anything else. $ fo $ they will stand the abuse and produce big numbers as far as HP and tq..

i used to hate the fart canners but those big bore bikes are a LOt of fun.. the ds's and 700's//
