I've never seen the parking brake cause a raptor to stall. It just doesnt let it rev. And I thought when it was in N that it allowed the bike to rev... I've had mine off for almost two years now so I cant remember exactly.

It sounds like an air/fuel problem. Since you've covered the air part, I'd think you are either getting way too much or way too little gas. Also, check to make sure the idle is turned up high enough to keep the bike running when you have the choke off. If the idle is too low it will stall when you put the choke back in or let off the gas.

 

well my parking brake on my blaster is broke after the 1st 2 days i got it and my yfz's parking brake blows after about 1 week (it still holds it but once pushed its not stoppin) but idk my yfz wont stay at and idle u have to ride it a lil to get it to finally idle

 

Let me throw my two cents in here. You said that you let it set about a month in your garage without starting it. It could be that the fuel gelled up in the carbs and now your pilot jet is clogged. You might change the plug and see what that does, if it doesnt help then you might be in for a little carb cleaning. Set aside a little time for this since you have to take off the front plastic, the gas tank and the rubber boot under the tank. Then you should be able to pop the carbs off and flip them over, remove the bowls and see if any nastienss is left in them of in the carb. remove the pilot jet, (the small one) and hold it up to see if you can see through it. It should be clean. If not get some carb cleaner and clean it, then go ahead and clean the main jet while you are in there. spray the carbs inside and out with the carb cleaneer and try to blow out the passageways. This should help you.

Hope you get it fixed as soon as possible.

Also do us one more favor, once you figure out what was causing it. Tell of us so we might know in the future!

 

Will try that. I will be sure to post what happens. Thanks again.

 

I ended up having the carburator cleaned and rejetted. They said that some sand had on of the valves stuck closed. It runs fine after they cleaned it. Cool! heading out to the dunes again this weekend! Thanks for everyone's help.

 

Replace that stock air filter with an aftermarket one. It will be the best $100 you ever spend. Your problem is exactly why those stock filters are crap.

 

I totally agree with starky . Think about it . if a piece of sand can get in there how much fine dirt is passing thru . Buy a pro-flow intake . if your worried about warranty yamaha sell them on the website
GYT=r filter andintake plate and get a prefilter cover .
Unless you want it to wear out so you can justify a big bore kit .

 

I have a proflow setup on my 2004 and had the same problem. It ran like $h!t trying to start it up so I thought I was going to have to take it to the dealer but instead tapped on the carbs a few times and what ever was blocking the fuel went by by or at the bottom of the bowl. It wouldnt even and have only taken it out on one trip when this happened. It sat for about a month also.

I used a screwdriver and set it up against the carb bowl and tapped it with a small hammer very lightly and it brought it back to life. I never had this problem with my 02 raptor.
