What did you do to your WR today?

4,495 posts in this topic

Ordered a "EKP" needle from the USA for $10.

Hope it works :)

Here in Australia they are $51 !!!!!!! :/

All jetting is a rip off here.

Makes tuning really difficult.

Just did zibbit's "Oil system upgrade" prior to leaving for Baja. Do a search on this, as it is pure genius, and is a wonderful mod to keep these WR's running forever!!!

It is where you basically add an oil jet from the Yamaha quad (YFZ450) into your clutch cover and it squirts oil up and underneath the piston. So oil hits the wrist pin bearing, and then falls down into the crank lubricating the crank connecting rod bearings. In my eyes, this is a must do!

Went to my local spot this weekend and didnt even make it 2 miles..........

IMG2271.jpg

Started back firing when on the gas, and then would only idle, limped it back , pulled the plug.

IMG2268.jpg

what the crap !!! I figure the missfiring caused the lean look of the plug, cleaned it up a bit and put it back in.

Started right up and ran great ......for about 300ft.... then POP POP POP !!!!! and it died and wouldn't refire at all.

Back at home I tested the spark and it seemed very erratic so it was time to whip out the manual and multimeter.

Everything was fine except the primary side of the coil pack which read .30 ohms and it should read .08 to .10 ohms.

Coughed up $114 to my local stealership and it might be here by thanksgiving :(

I hope thats the actual issue

So glad this didnt happen at the places I normally go. It would have sucked bad had I been 20+ miles away from the truck.

bummer. I had problems too..

went to check my valves.. accidentally cut the big rubber gasket on the valve cover.. such a tight fit to get it out!

valves are (way) out of speck, so need to go to stealership to get shims and order a gasket. ugh.

Think I'll get a hotcam while I'm waiting.

I thought 07-up already had oil squirt on the wristpin?

Keyed ignition!

this: $15 off ebay. It will help keep the "honest people honest" if you know what I mean. Good for the times when I don't have my disc brake lock on me

It has 4 wires.. green and black w/ white strip are not used.

The other two are used with the brown and solid pink wire.

Got my new coil and it gives a way better spark and then I found out why...........

IMG2357.jpg

This is the connector on my old coil. The pin on the left is corroded away at the back. !?!?

Also got around to a couple long overdue tasks,

Extracted 2 broken bolts that the PO left frozen in the frame that hold my left radiator on .

Dispite all the red loctie that went shockingly well, usually for me it gets pretty ugly.

And finally installed the TT AIS removal kit. I am really sick of the decel poping .

I bought my first dirt bike in 19 yrs - a super nice 2007 WR450 with a few go fast goodies. My previous bike, that I sold back in Oct of 1993, was a Yamaha XT350. I cannot believe how hard this WR pulls - so far Ive been trying to figure out what all has been done to it, as the previous owner didnt seem to know much; he said he bought it 2 yrs ago just like you see it. This is what I know has been done through my reading on here, looking through the TT store and then inspecting the bike: moose radiator supports; FMF megabomb Ti header; LEXX MX slip on; AIS removal kit; grey wire cut; TwinAir airfilter; Ready Racing oil filter cover; Race Tech rear spring SRSP 6228 5.8kg ; Race Tech Front springs; Alum chain case guard; moose chain guide; MSR hand guards & deflectors; aluminum skid plate

I traded a 2000 Polaris Xplorer with winch and plow for it - I think I came out ok. :)

Is there anyway to tell if any carb work has been done to it, without tearing the card down?

retard your ex cam whilebyour at it

I will but I kinda feel like I should fix the jetting issue I have first. Which is a just barly open throttle cut out that ,

thanks to Krannie I beleive is a pilot circut adjustment issue. Once its running perfect I am retarding the

exhaust cam.

What tip are you running on the Lexx slip on ?

I thought the " quet tip " one it came with was good

and then I took it out and used the "race tip"it also came with

and the power increase is hard to give up. Its just loud as hell

but sounds badass though.

Thinkin about trying the 2 other tips that RMATVMC sells for it.

Also what what jetting changes did you have to make when retarding the ex cam ?

      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
      6. Pol Tarres (Beta) 6:52:57

      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
