It made a difference on mine.you sure you unpluged the right one? theres 3 that look the same.If you dont believe me just go to raptorforum.com and they'll till you.

 

I unpluged the one that goes to the transmission. I checked the wire diagram to make sure the wire colors were correct. The one I unpluged matched the book. I have a 2006 model.
The colors on each half of the plug are:
Side A three wires) - Blue, White & Black-w/Blue stripe
Side B three wires) - Pink, White & Black-w/white stripe
Please let me know if this is not correct or if you have a different model year.

 

You unpluged the wrong one. The one your suppose to unplug has 3 wires. It should be next to that one. Let me know if you found it.

 

He did unplug the one with 3 wires

 

????? then i'm not sure whats wrong with yours but i'm at least hitting 80-83mph.

 

How have you been measuring your speed? Do you have a trailtech computer? If your bike was modified and the other guys was not then you might have a higher top speed and the speed sensor was limiting you were as his might be stock and thats all the bike will do.

 

Well i havent GPS'ed my quad since i unpluged my sensor and it did 77-78mph. But i know it got faster because i can fell it keep going longer in 5th gear. And before i unpluged the sensor me and my brother would race my predator 500 and Raptor 700 and i would beat the predator 3-4 quad lenths then i unpluged it and would pull 6-7 bikes on it. And my raptor is stock. Predator has yoshi slip-on.

 

I think you need to measure your bike with a GPS again before you jump to conclusions. Unplugging the speed sensor is starting to sound like it has a placebo effect.

 

Okay man if you dont believe me go to raptorforum.com and ask if unpluging the sensor will make a difference. And just about everybody will say "yes"..there are a FEW that say it didnt make a difference but there's more that say it did make a diff. And if i beat the same quad twice 1) Sensor pluged, Another sensor unpluged and beat it by more bike lenths with it unpluged i think that means that the sensor does give you more top speed. You can also see that your going faster in top speed.

 

I believe that its suppose to have something to do with the timing curve.
