i JUST PUT MY NEW RENTHAL (BANSHEE) HANDLE BARS ON MY RAPTOR AND IT RAN FINE GRANTED IT WAS JUST A LITTLE 30SEC RIDE BUT THEN I WASHED IT AND ANOTHER 30 SEC RIDE AND AT ABOUT THE 31 SECOND IT MADE A MESSED UP NOISE LIKE WHEN THE PARKING BRAKE IS ON AND YOU REV IT TO HIGH SO I SHUT IT DOWN AND NOW IT KEEPS DOING THAT BUT ONLY WHEN YOU REV IT. COULD THE CLUTCH OR PARKING BRAKE BE OUT OF ADJUSMENT OR IS IT SOMETHING WITH THE FUEL. SOME HELP WOULD BE MUCH APPRECIATED THE DEALERS AREN'T OPEN TOMORROW AND IT IS REALLY STARTING TO RUIN MY TURKEY DAY SO. IN ADVANCE IF YOU GIVE ME SOME ADVICE THANKS

 

hey...sounds like the same thing that happened to mine...lift up the seat and look up under by the gas tank...way up top...if there is a hose there and it is kinked...unkink it! Mine was running fine one day and did the same exact thing. It must move on it's own. I rerouted mine out of the brackets that it was in and routed it through one of the airbox clamps down beside the airbox. hope this helps

 

sounds like to me that the switch on your p-brake may not be compressed all the way... it is fairly common prob with there cheesy perch switches.... I think that its the one twards the front on the bike on your clutch perch... you could have got your p-brake cable out of adjustment or something along that line... I am going to get rid of the p-brake soon befor I have any probs with those stupid switches...

Hope that pointed you in the right direction

 

THANKS AGIAN FOR THE HELP I WILL CHECK BOTH IN THE MORNING I HOPE IT IS AS EASY AS THE FUEL LINE HAVEN;T SLEPT ALL DAY GONNA GET A FRESH START BEFORE EATING THE BIRD THANKS AGAIN

 

its amazing that that little hose keeps that monster of an engine from running right.

 

Man it sounds like what happened to mine a week ago. I was ridin some trails to the local sand pit when from out of no where it started sputering and back fireing. The noise was identical to the sound of the rev limiter on the e-brake. I did a visual inspection of the bike and saw nothing out of order. needless to say the slow jerky ride back to my truck was heart breaking!!!
Anyway brought it back to the dealer and demanded it to be fixed. Turns out a small rock had found its way up the right carbs breather hose and was being sucked under the neddle every time I gave it gas. They said it prob. happened in a reverse rippout which the raptor is so known for.
well good luck

Maybe you got water in with the fuel when you washed it

 

bypass the wires on your clutch perch! I put on a cr 250 perch and lever and had to, IT IS MOST DEFINITELY the wire, If I remember right take the plug out from the emergency brake at the perch and cut the wires (I think you eliminate it by breaking contact) do that and rev it, if it revs it's fixed... email me tomorrow if u need info..

 

my banshee done the same thing.it would ilde fine but when you touched the gas it would bog down and finely die if you stay on the gas we unpluged the t.o.r.s.unit and it ran fine.i dont know if thus will help with your raptor but i thought i would let you know because it sounds like the same thing.good luck. 00 DS & 00 banshee

 

let us know which if any worked.
