I am sure you know this ,but, these carbs have an accelerator pump ,which, shoots more fuel into the intake, thus, may foul your plug when the throttle is chopped. Good luck at the dealer just be nice to him...I have the same problem I have a wicked evil temper too. People are way more helpful when I don't rip their heads off. It has taken years to relize that. I am sure he will be willing to help. He doesn't want to loose a future customer.

I feel absolutely no loyalty to Yamaha. I totally agree that you and all other owners should not have to be fighting these problems. It appeared to me that your original post was a thinly disguised attempt to pitt one brand against another. Apparently, I was wrong and I apologize for that. Not much more I can do than that.

I wanted to ditch the POS many times, but after I finally got things "dialed in", I would not give this bike up for anything.

I'd drain it out and then pour it on the groung and light it. Some times I make little gas rivers
and float little green plastic army men in boats
down em. Fire crackers are good too!
Then I'd get some new fresh gas. I like the good stuff c-12 b-32 some guys say ya dont need it
but You cant beat the jetting consistancy. And it smells good too. You should be able to get a 55 for lessthan $225 Or for $225 you could get 45
plugs. Get the gas. I switched to decaffe a coupl years ago. You should try it.

I am with Herbski or Herpies or whatever his name was. Go with the decaf and a little river of fire, sounds to me like you are heading for CNN about now.....Take the piece of crap back to the dealer and go with the old school..I have an AC Corba that beats the **** out of any Viper that comes along and it's 34 years old...

Most here seem to be blaming you for the faults, myself included. I can speak for myself and maybe most, that were sorry for your troubles and glad we don't have to endure the crap your going through. These bikes are assembled by HAND so human error can effect at any time.
We know that were proud of these machines and if you can get yours dialed in you'd be happy as well.
I know I can speak for everyone and say were glad were not in your shoes if you do have a lemon.
Do take your bike back to the dealer, but try one thing.
Wet plugs equal too much air = rich setting.
Check your pilot airscrew at the bottom of the carb. Stock setting is 1 3/8 turn out. Turning in equals lean setting turning out equal’s rich setting. (These are set manually by humans at the factory) It’s worth a try.

Go talk to a bunch of guys who own Porche 911's, Lamborghini Diablos, or Ferrari F-50's. I bet you would find a few that have had problems with their machines they couldn't fix themselves for free. They probably spent a lot of time at the dealership and plunked down some serious coin to get the issue resolved.
I think the problem is that you're not being realistic. First off, you have no stats about the model or year of your motorcycle that indicates how frequently this problem occurs, yet you bash Yamaha for making bad motorcycles in general. I saw quite a few posts here that indicated that they've never fouled a plug regardless of what they've done to the bike (like myself).
Next, you expect that your highly sensitive racing bike run perfectly out of the box. As a lot of folks have indicated here, once you find the fix, the problem goes away. These bikes run awesome when they're dialed in and pretty poor when they're not. I heard you mention a lot about fouled plugs, but not much about structured problem solving to investigate what is causing the fouling. Perhaps instead of riding it and continuing to foul plugs, you should brainstorm all possible reasons a plug could foul (perhaps with your dealers assistance?) and systematically eliminate possible causes until you uncover the root cause. If you're not inclined to do this yourself, I agree the dealership should do this for you since your bike did it since you bought it.
Also, you're kinda preaching to the choir here. Everyone (or most everyone) on this board came here to learn about their bike and perhaps how to make it better. Most came because they have an issue they think a fellow TT'er knows the fix for. So perhaps instead of initiating a message by bashing Yamaha for making a POS bike, you could fully explain your problem and solicit feedback on possible fixes? Seems all you've done is alienate some really experienced folks from helping you out.
I am truly sorry your bike isn't running as well as other bikes here. I really enjoy my 426 every time I take it out (except the one time I put the cam back in it with incorrect timing...DOH!). Unfortunately I'm not an expert on plug fouling and don't have much to offer to you. I would suggest if you don't have the money/time/willpower to troubleshoot it yourself, take it back to the dealer and demand they fix it or exchange it.
As for all of you that wrote in complaining about how Yamaha won't pony up to their mistakes like automakers, keep in mind that automakers sell millions of cars every year and make billions of dollars doing so. Because of that, some very powerful consumer advocacy (sp?) groups have formed that make life hell for auto makers if they screw up. Ford/Chevy/Dodge/Toyota won't willing admit to failure and offer new parts and free labor to fix something unless they're pressured to do so. I think Yamaha gets away with this not because they're any different than the big automakers, but because we as consumers allow it to happen.
Sorry for the long post, work is boring today...

I have owned numerous bikes and never wined about any of them. And if I did buy a Honda, KTM, or any other two stroke 250 I know what needs to be done to work the querks out of them. Right now I have to pay some guy 60 Bucks an hour to figure out what the hell is wrong with my new bike(right now it's sitting at ACtion Motorsports) Sereously, you can't tell me that I have unreasonable expectations.
And another thing, I have always wanted to own a 426, I Had nothing against Yamaha, I have something against a company who charges me 6 grand for a god dam rubix cube.
And Boit, I understand.
P.S. Beakley, if you can't sleep tonight, just jump on T.T. and tell me I am right. It'll help.

The point I believe Mike is trying to make, and I can agree, that when Honda and KTM make a bike that starts like it's got an e-button, even when it doesn't, why can't Yamaha do the same thing. It's stupid.
That aside....Mike, how tall are you? ONe thing my dad DID do that has significantly helped his starting abilities, is build a box to start it on. He is 5'6", and has a tough time starting it on level ground. he must be a good 6-8 inches higher to get it to start. I am 6'0", and yeah, I have had tough times starting his bike too. I would think it is indeed all jetting though. He is still running stock.
The thing is, the bike doesn't even sound like it is TRYING to start. Something else we do to get his to fire:
-turn the fuel off.
-Tip the bike over until the carb drains.
-Hold the throttle WIDE OPEN. Hold in the compression release.
-With the throttle wide open, kick the bugger 8-10 times, just like a 2 stroke, just plow through.
-Let go of the comp. release and throttle.
-Turn the fuel back on, and do your normal routine. This should help.
You are not alone in your starting harrassment, but there is a simple fix to help but not entirely cure hard starts, and it does not involve blue wires, grey wires, or anything else, it probably involves jets.
Needless to say though, my dad and I can understand your frustration, as like I said, I can walk over to my stock ktm, on an old plug, and 1 kick she'll fire, yet dad can fight for 20 mintues sometimes to get his to. That is indeed frustrating.
