Where we ride at we have a drag strip set up. It's 900 ft long. On a nice Sunday afternoon there is 40-50 quads racing. The YFZs are king. They pull everything else out of the hole so bad they can't catch up. There are some 450rs and Predators that are running VERY close, but the Raptors are not a factor.

Good that you expect more criticizing, because when I see your post in a yfz vs whatever thread I expect plenty of instigation.

A reasonable estimate is 43hp for a piped and filtered raptor. About the same for a piped and filtered yfz. Yfz has a significant weight advantage and IMO is easier to launch in a drag race, at least in stock chassis and suspension form. Throw in the fact that you are more apt to see experienced and smaller riders on yfz's and larger and more recreational riders on a raptor and the real world comparison becomes a little biased. Add that most yfz pipes are capable of an extra 5 hp while most raptor pipes are limited to 8 which only evens the hp field, and that raptors are harder to jet so most are not running the correct A/F ratio. You have to get into Sparks, LTE, LRD, CT, or Barker (there may be one or two I've left out) if you want to break the 10 hp barrier and most atv owners dont want to spend 500-800 dollars for a pipe on a trail bike.

I could go on with other factors but you get the idea that just becuase your piped yfz and the ones you've seen can beat piped raptors doesnt mean that a raptor cant gain 12-15 hp from a pipe and filter.

 

poor raptor is going to loose sorry to tell you just because it is bigger does not mean it is faster. the only way you have a chance is if you way a lot less.

 

Good post Maddog. As are all of the posts I read of yours. Straight facts and nothing more.

As for me instigating. Give me a small break if you can. I generally don't reply unless on these threads unless stupidity rears it's ugly head in a bad way. You and I both know that this whole internet racing thing can be pretty funny at times. [img]i/expressions/face-icon-small-wink.gif[/img] We've both seen bikes win in interent racing that have no chance of winning these races in the real world. [img]i/expressions/face-icon-small-shocked.gif[/img] That's usually when I step in to help the situation.

Don't hate me for bringing the truth out on occasion please????

All of these bikes we discuss are great bikes in thier own right. No one can deny that. I'm not stupid enough not to realize the fact that a Raptor will beat my YFZ in a top end race. But in the real world where all of us do these weekend shootouts, top end is rarely seen. I'm not stupid enough not to realize the fact that a Raptor is helluva lot more comfy than my Y. I could go on and on about the pros of the Raptor vs the Y. But you and I both know that the tables are reversed in situations where the Y shines. These are the areas that some of these 14 yr old interent racers don't want to see with their cybervision.

THIS IS ALL FUNNY TO HEAR, I HAVE AN 03 RAPTOR WITHA CURTIS SPARKS PIPE,HEADER AND JET KIT AND AIR FILTER AND I SMOKE THE YFZ 450 AND IT NEVER CATCHES ME AND I REALLY LEAVE THE NEW HONDA 450 SITTING IN MY DUST, EVERYONE TALK AS YOU WANT BECAUSE I HAVE EXPERIENCED IT AND KNOW MY RAPTOR IS FASTER THAN A YFZ450
