Going to go out Satday as soon as i get my Jetting spot on, with my gps and take my Raptor down a long flat pavement road.It has a CT head pipe, muffler,Pro flow air box with no lid.Stock size tires, 170 lbs me And see top speed with a 12 tooth front and a 13.Anyone wish to know the speeds i will post Sunday!!!Skydog[img]i/expressions/face-icon-small-happy.gif[/img]

That would be cool. You might wanna post your elevation and your jetting setup too.

Also one thing to keep in mind is the GPS can be off by as much as 4 mph I've been told. Might wanna make a couple runs with each setting to try to minimize the amount of error.

take your gps with you in the car and see if it is on the button. My friend tried this and it was correct with his car at 40, 50 60 and 70 mph. I would say it is right on.

Sounds good Skydog! You gonna wait for your Dynojet kit to come before you do the runs? You should throw in a 14 tooth sprocket also!

Yes going to wait for Dynojett kit should have it to day!One more thing i am a 780 feet above sea. i was way off before.For the gps it is spot on i have tested many things!For the 14 gear i do not have one so just going to run 12-13 Thankyou guys Skydog

My friend did this with his Raptor and a GPS. The only mod he has is a White Bros slip on. He did it with a 14 tooth, and it registered at 74 MPH, and a 12 tooth at 70 MPH. He was a little disappointed that he only gained a few MPH going up 2 teeth.

I ran my raptor stock down a paved road when I first got it,and my gps reading was 72.1 mph.

Skydog, I can get a radar gun if you want to use it along with your gps.Let me know if you and I can bring it with if we go out tearin it up this weekend.later rpm

There is a site I joined that has done this with 12, 13, 14, and 15 tooth sprokets on stock, G-YTR, WB E-series, and Pro Circuit T4 piped Raptors. They have clocked them with radar, GPS and trail tec speedos. They also did it on tar and dirt, I was kind of surprised at the difference between dirt and pavement. It is a pay site but only 3$ and its pretty interesting. The site is ATVtesting.com

WOW it went 81.9 mph!!!With the 13 tooth front on, did not try the 12 needed to ride!This was down a black top road and it had a very slight down grade and a mean very little!It hit 9000 rpm i felt it hit the rev limt! This was on GPS and it is right on. Had many friends that where over all of them where like wow.They all bet about 75!!HA HA See YA!! Skydog
