What can a stock YFZ450 run in 300ft?

 

completely stock = 5.7
rejet, cam mod, spark arrestor removed = 5.4
Piped w/intake & better tires = 5.1

 

What can a stock Raptor or Shee run in 300ft on same type of situation that the YFZ would post those times then DirtDragon

 

A yfz up here with wheelie bar, pipe, filter, jetted up ran a 5.5 as the fastest time.

With a pipe and filter it ran 5.8's. Another yfz up here ran 5.4 with cam mod, pipe, filter, and jetted up with longer swinger. That was the fastest time I have seen.

 

That sounds awfully generous, I hope those are dirt times...

A good zilla was running 5.2 with headwork, high comp, bore job, and drag pipes.

My raptor was running 6.2 piped and running fat.

My times are sand though, I have no dirt times.

 

These times are based on dirt tracks in NY. The best I have seen a 727 raptor run is 5.2. We have a YFZ on a 30HP shot of NOS that will run 4.8 at some tracks. The 727 Raptor on 45HP shot of NOS runs close to 5.0

Please keep in mind the YFZ times posted before were done by my wife who weighs 105Lbs!

I hope that you guys are running on a fairly slick track... that 727 should be well under a 5.2!

And Ken keep in mind that the times you are posting are at the Spencer track and it is a SLICK track, so they may pick up a few tenths at Fairplane... I don't know if they will hit a 5.1 or not but guess we will see on the 7th.

 

I'm hoping the times go up by .2 or .3 at fairplane. But didn't Bird run his best times at Spencer instead of fairplane?

 

You better hope for more then .3 if you want to get in the #1 spot LOL

Yes birds times were better at Spencer but he also had his bike tuned in better!

 

Don't worry, I'm planning on busting a 4.5 first run at Fairplane. LOL. Might even break out that 4.5 tomorrow night at the Jackson County Fair. [img]i/expressions/face-icon-small-happy.gif[/img]
