started taring the 99 down some more and realized after a gallon or so of gas leaked all over the garage that the petcock isn't working :thumbsup: then i try to remove the tank and every bolt is different and rounded off or so rusted i had to go a size up... this is gonna be more of a project than i wanted....lol. i don't think it was in this bad of shape when i originally had it :thumbsup: anyone know where i can find a full bolt kit? hopefully the threads are messed up in the frame

Took out my WR400F after installing the FMF powercore 4 exhaust (with the FMF powerbomb header I already had).

Sure enough... the bog is now back. Very minutely, and not nearly as bad as before, but it's definitely back. Time to focus on jetting I guess?

EDIT: The issue is only at idle? Perhaps the idle mixture is off?

Try turning in your air/fuel half a turn and your idle up half a turn...

Will do!

actually on my 07 some how the air/fuel screw backed out all the way and fell out :thumbsup: i put a new one in and turned it out 3 turns i believe and the bike would bog and die. i kept turning it out untill it was barely hanging there and the bike ran perfect till of course it fell out again. worked on it for a couple hours in the desert then a buddy came and had to turn the idle up like 4 turns! then it's been running great ever since :thumbsup:

Rule of thumb. If you have to back it out more than three turns you need a larger idle jet. :thumbsup:

Yeah some how both screws got adjusted out at the same time cause the bike was set up cherry back in 08 (put on some machine that tests everything) and it never ran bad until the air/fuel fell out.

The Revloc Dynaring would be my first mod on that list. I love mine and would never go back. You couldn't give me my money back for it.

If you're on a wr400F and don't have powerbomb header it should be the first thing you do no matter what. It isn't from a performance standpoint, it's from a longevity of your engine standpoint?

Why is it relevant to your engines survival? The stock header makes changing and/or cleaning the oil filter a nightmare, as it requires removing the header... etc etc. It turns a 5 minute job into an hour or more long job, and so most people don't do it frequently enough.

With the powerbomb header, it's out of the way of your oil filter, and you can make it happen no problem!

Oh yeah, and adjusting my idle and air mixture setup a bit seems to have done the trick. I really need to figure out exactly where I'm at though out and see if my pilot needs adjusting. Temperature is a factor as well possibly...

I'll keep experimenting. While there is a very minor and slight hesitation off of idle, when riding, even at a lugging rpm, I can grab throttle and stand the bike straight up no problem.

Well I tried to put my 07 on the charger so it'd start but it still just clicked... I think it's a relay or something cause I can hear the starter trying to turn. Any helps appricated and I've got another thread going, trying to sell it and the starting issue is a black eye

Could be a bad connection in the harness or a bad ground. If that's the original battery, it might just be time to replace it. I figure on a battery every couple of years. If you've charged it and when you try to start the bike it pulls the battery below 10.5v and it doesn't immediately come back to 12.6v when you release the start button, then you're battery isn't holding a charge and it's time to replace it.*

* too much bother (imo) to try to regenerate sulfated cells, but some folks try it anyway.

yeah i'll see what happens to the voltage when i press the button... may have to toss a new battery in. a couple people hit on $3,500 then i dropped to $3,250 when they heard the damage on it... they havn't gotten back and i'd really like to not go cheaper than that cause i'm needing money and how much i need is pushing $3,000 and i'd like to keep some...lol

Relacing my rear wheel right now! Going to go get a proper spoke wrench! Man oh man were the old spokes destroyed. This should be pretty good though!

After this I don't really have anything I have to do on the bike. I'll probably put a new piston and cam chain in at some point this summer so I can relax knowing my bike is pretty much good to go for a long while!

      Rockstar Energy Husqvarna Factory Racing Rider Tops Podium in Belo Horizonte

      May 21, 2017 – (Motor Sports Newswire) – With the four-day event cut short after day two due to environmental concerns beyond the event organisers’ control, Rockstar Energy Husqvarna Factory Racing’s Graham Jarvis has been declared the winner of the 2017 edition of Minas Riders having ended day two as the overall leader.

      Jarvis entered the second edition of the Brazilian race determined to start things off with a victory. Ending a rain-soaked prologue as runner-up, he then went on the attack when the race entered the mountains for the first off-road day.
      Pushing hard throughout the five-hour plus opening day of hard enduro racing, the Husqvarna rider claimed a three-minute margin of victory to establish an early lead. Maintaining his position at the head of the field with second on day one, Jarvis was holding a two-minute buffer over his nearest rival Cody Webb as the race entered its second half.

      But with days three and four cancelled, Jarvis unexpectedly found himself as the early winner of the 2017 edition of the Brazilian Hard Enduro Rally.
      With victory in Brazil, the Rockstar Energy Husqvarna Factory Racing rider now looks to add one more victory to his 2017 campaign at Austria’s ErzbergRodeo in June.

      Final Classification — Red Bull Minas Riders 2017
      1. Graham Jarvis (Husqvarna) 5:46:47 
      2. Cody Webb (KTM) 5:49:29
      3. Alfredo Gomez (KTM) 6:03:51
      4. Philipp Scholz (KTM) 6:15:01
      5. Paul Bolton (KTM) 6:37:28

      Hi, my stator on my 99 wr400f sumo needs a replacement but I cannot seem to find any here in Ireland and I need it ASAP so 3 week deliveries can't do, will a stator from any other dirt bike fit right in as a replacement? No wr400 s here so I need to look for other ones for breaking, thank you!

      This current fad of people going all ga-ga over KTM motorcyles is hilarious.
       
      Over priced, under engineered 'fashion' statement motorcycles are duping people left and right into this fake engineering game.
       
      Iv'e seen this same thing before with cars: Mercedes, Audi, Porsche, Maserati, Ferrari, Fiat, Lamborghit, etc, etc.
       
      Create a really stunning 'hook' of a machine, that everyone wants to own, then sell enough to figure out how to keep them from blowing up, and falling apart, hopefully by the next model year or two.
       
      Oh, don't get me wrong....Mercedes does make some really great cars. But MOST of the cars they make are not so hot.  They are poorly designed, over priced, and un-reliable.  Same with the other euro manufactuers. Fiat make several really great cars, like the 500. But all the rest are just garbage commerce.
       
      This is EXACTLY what KTM is doing. 
       
      Throw 15 different models on the market, all based on old technology, but with shiny billet parts, or ultra-impressive specs, and see what happens.
       
      KTM is providing their customers with sub-standard quality and engineering on dozens of levels, selling it as 'high-tech' and then ignoring all the issues with oil starvation, throttle bodies, frames, triple clamps, shock mounts, CDI's, bars, brakes, rims, hubs, all failing, braking wearing out extremely fast, or in the case of motor internals, make them to such terrible tolerances that you cannot change broken parts with new parts, unless you buy the matching case it was machined to.
       
      I have never seen or experienced such CRAP sold as a premium brand in my life, accept Audi in the 90's and Maico in the 80's. 
       
      I've owned (2) 2012 KTM's that both failed on several levels, that the KTM factory, KTM usa and my dealer could not resolve. 
      I even had KTM USA tell me 'that's just the way it is with new bikes sometimes. We don't have an answer to your problem, sorry". 
       
      My dealer was so frustrated that they now refuse to work on any KTM that has been modifed in the suspension, electronics, or motor, period, even out of warranty.
      They also will not replace any internal motor parts below the piston without replacing the entire motor, no exceptions.
       
      Yeah I know: ..... " My KTM is great, I've never had a problem with it" .  Well good for you. You are in the 50% that actually get a 'good' one.
       
      Did you know that until recently  (2010) KTM would and did make as many as 6 different gasket sets for one model of motor, depending on what portion of the year it was made? They actually look up gasket kits by serial number, because the factory produced a motor with so many flaws and failures that they had to upgrade the motor in the production line 6 times in one year....rather than just get it right and then push it on the general public. 
       
      I talked to an KTM partially sponsered Enduro team at a D36 race in 2012 about KTM reliability, and this is what they told me:
       
      " Oh, we get 50-75 hours out of the factory motor, no problem. They run great, most of the time. Not quite as long as the Yamaha we used to run, but they are Ok. The real problem comes when we try to rebuild them. We cannot get a rebuilt motor to last 1/2 as long as a new one, because there are so many parts in the KTM motors that are stressed at 100% from day one, that the whole motor, not just the top end, wears out very fast". We try not to rebuild the motors, we just sell off the whole bike and start over with a new one."
       
      Hopefully, honest, non-Germanic companies like Beta and Sherco will take some of KTM's market share away.
       
      Long die KTM.

      Are you suppose to be able to go through the gears with the cases split? Got my 03 yz450 split and its really hard to turn the shift cam with my hand. I can get neutral, 1st, and 2nd but not the other two gears. All of the components are in great shape. No sign of wear
