Replace the pilot jet, do not waste your time trying to clean it.
Easy for you to say! Any idea how much they charge for one of those up here in Canada???
Seriously, spend 2 minutes cleaning it out with a toothbrush, compared to the 20 bucks the dealer wants for a 5mm piece of Brass!

You have no idea how many people swear their pilot is spotless. They soaked it for a month, they scrubbed it. Spent days trying to get the bike right. I spend two minutes putting in a new pilot and off they go.

I'm in Canada to so I think your dealer is ripping you off in a big way. I just bought a few pilot jets and they were only $6 bucks apiece. Find a new dealer. WR Dave
Hey Matt, Me too. $5 or $6 bucks for jets.
So you guys are telling to stop wasting my time cleaning the pilot jet and just get a new one. Now you tell me. Maybe that explains the stutter while on the pilot circuit.
Hey James, I would get some fresh gas in there. Drain the old stuff to use in your lawn mower.
Here is a fantastic thread on working on your jets. With photos too.

And then they wonder why they go out of business.
We do have some places that will sell them cheaper but you usually have to wait for them to come in, then they ordered the wrong one from parts canada!
My brother in law lives in Alberta and he seems to get better prices on everything too, unfortunately - around here, it's a 1 hour drive to get better prices - and with the gas prices the way they are, I'd rather spend a little time with a toothbrush.

does the bike start easy when cold, 3 kicks max??
First new pj, you need to elimate this.
is the gasket on the floatbowl -- good?
make sure the slide is properly installed and verified!!!
does the gas from the tank run freely from gas line, not plugged? and or at the air vent?
and yes I am serious about the mouse nest thing in the muffler and or air box?
intake boot is alright?
no leaking at the exhaust flange?
do you know anybody that has a wr426 or 450 and could try his carb?
and was the bike runnin well last year?
let us know how you make out? we are all hoping that you can get it running soon!

Thanks for the response and tips. I recleaned the entire carb, one thing I did was clean the throttle valve and the wheels that attach to the valve and slide up and down. I cleaned out all the grease and re-assembled. Now the throttle sticks!!! The manual says to put fluorochemical grease near these wheels (what kind of grease is this), and do I actually put grease on the wheels that move up and down (there are 4 wheels, a little smaller than a dime). Sorry for these questions but I want to do this correct. Thanks. JIM.

The grease is for the the actual wheel axles, they specify flourocarbon as it is fuel insoluble.
Did you replace the pilot jet and not merely attempt to clean it?

you verified the slide plate is installed correct (it should look like it's installed wrong so be careful).
You can use Molybdenium (moly) grease on those wheels - it's usually dark grey.
Once you have verified that everything is good and you have your idle and fuel screw set to their default positions, put in a new plug, once it fires and runs, you'll need to fine tune the carb once the bike has warmed up.
