Boats.net/ Partzilla informed me that the part is not available anymore through Yamaha anymore. I ordered something through another Yamaha dealer, but I don't know what the part number is. Its supposed to do the same things and should be here early next week.

I'm interested to see what you end up with . I'm keen to know the part number when you get it ..

I tried to order through boats.net a few weeks ago and found the same thing no longer available .

I got mine through eBay .

I have been watching this thread even before I brought home my 2012 WR450 (which was this past Wednesday 11/20, got it super cheap too) and I have had no such issues. When its cold I always kick it after pulling the knob, but once she's warmed up I have little to no issue with E-Start, even in gear (as long as the clutch is pulled in)

 

One question, the Yamaha website states the 2012 as having a CDI ignition and the 2013+ as TDI - Anyone know which is which and whats the main difference? Just wondering if that may have anything to do w/ starting it up

I was wondering the same thing about the CDI, I also picked one up on this past Saturday for cheap and have been having trouble starting it. I think I am going to hit the dealer and ask for the sniffer test that was mentioned earlier in the thread.

I asked this question before but don't think I got an answer. after you made these adjustment have you rechecked the settings with the gytr tool?

I find this interesting because I've stalled my bike on the trail and it started back up. do you think its a temp thing that is causing it or elevation or....?

There is nothing that you can check but the Map. The map does not change if you adjust the CO levels. The map from the GYTR is just a lookup table that the ECU looks at to off set the base settings (tuning). The CO level adjustment is a separate lookup table that is adjusted by the FI tool. It should have been part of the GYTR's tuning parameters. But do to CARB and the EPA It's a dealer only adjustment. This is not only dirt bikes but its the sane for street bikes, snowmobiles, outboards, and boats. And the FI tool works on all of these built by Yamaha.

The CDI is a hotter but shorter spark and rev's higher than the TDI style. CDI also cost more. The 2010 YZ's are CDI but are now TDI. I would think both are good on the WR's.

At a glance, it looks like the extra drag of being in gear with the clutch in creates too much resistance for the starter (1/2 of the clutch is spinning when you start or kick a bike in gear with the clutch in)When in neutral with clutch out there is less resistance.

I know my '06 has a rather marginally designed starter motor, mine, like many others, will not physically turn over if the piston stops at TDC. A very rare occurance, but when it does happen you think you have a dead batt or a bad starter motor

I just received the tool from Honda east Toledo and it is the 90890-03182. Its identical to the others using the same part number. The Yamaha sticker on the box also has the number Y070515T and a separate sticker has the letters K@L with the number 35 3028. The parts guy mentioned that it was coming from the Yamaha warehouse, so I don't know why he had no problem getting it when others say they cant. I plan to try it out tomorrow, with hopefully the same results as others have had.

Should have no problems. Green wire to airbox, alligator clips to battery .

Ignition off. Hold down menu button and while holding turn ignition on .

Press up , should read co, press menu then adjust accordingly .

Turn off ignition.

Repeat steps to check .

How much $ for this tool?

Lexx makes an efi controller for the YFZ450 quad. I wonder if that would also hook up to the WR ?

Also if you are using it for diagnostic the codes e.g. D02 etc are all in the Yamaha WR service manual

Well, not sure what happened to my new Earth X battery but it wouldn't start the WR today. Started the bike fine over the last few weeks in the garage.

 

Got out to Gorman this AM and click, click, click. Had to kicj=k the bike all day which wasn't an issue as it fires right up. Will be contacting Earth X to get a replacement battery under warranty. Will let you all know if there are any issues getting the replacement.

Maybe I should have got the power commander v.  That's a lot of extra wires and crap to have under the seat though.

I followed Cassinova's directions, and it seemed to work properly. I don't have any way to check the exhaust, so I set it to 8, it was at 0. I just need it to warm up or dry out a little to see if there is an improvement.

 

Thanks for the help everyone.

Anyone have a Chinese fi diagnostic tool that doesn't connect, have you tried just the center pin plugged into the bike, like so 1385876381111.jpg

      Hello everyone, been looking around on here for a couple weeks and figured I'd finally drop my question for some feedback. Looking for a bike, obviously or I'd be on a different forum, somewhere in the 250/300 range. Heres some info about me and the typical riding I'll be doing..
      My specs: Male, 190 lbs, 5'10, 28 years old. 
      Riding Experience: Two wheel mostly street, R6, R1, Harley etc. I've ridden most of em. Off road has been mostly quad, except one trip down the trails on a Yamaha 450 2t (holy moses that was quick). Ridden quads for a few years, Polaris 850, Yamaha/Honda 250's (banshee style) at Silver Lake and on trails. Trails we ride are in Grayling which are a mix of hard pack and loose sand (tank trails). 
      Planned Riding: the above mentioned sand dunes and trails. Doubt I'll ever touch an actual Mx track. Will use a paddle tire when in the dunes. In my mind I've narrowed it down to the KTM 250/300 XCW or Yamaha YZ250X. Not really a Honda fan. 
      Not trying to open another KTM vs Yamaha thread, Ive read plenty of those. Just looking for some feedback and ensure these are the bikes I should be interested in and if 2 stroke should be my route? I like the easy maintenance but also like the idea of fuel injected 4t. I don't want to be beating the heck out of a 4t in the dunes and turn it into a bigger $ pit than these toys are already. I would prefer having a headlight, 250X does not come with one while both KTM's do (unless I go Yamaha 4t with the WR250f). Thanks for your feedback..

      I am looking for a YZ125 and have found a 99 for 1300 and an 03 for 1600 both in pretty nice condition. Obviously going to negotiate the prices down however I was wondering which one you guys would suggest. Ive been doing research and know that the 03 is lighter with a modified frame though it has a 5 speed. The 99 motor is well liked for the power and reliability.
      I will be doing strictly trail riding so whats the better option here?

      So I was cutting my neighbors lawn when i came across this bike in my neighbors barn. They said i could have it for free and i thought it would be a great thing to try and fix up. But after looking at it and doing some research i cant find what it actually is. I believe  it is a 1985 YZ 125, but i am not sure. Anyone know what it is and where i might be able to find some parts for it? Or if it would be better just top sell it for parts. Thanks!

      PRICE DROP
      For sale is my 2015 Beta 350RR. 2734 miles and 120 hours. Just had some top end work done by Sierra BMW and BETA. Fresh air filter and oil. This is an awesome dual sport bike. Or you can strip the lights and turn signals and have a single track weapon, your choice. This bike will do it all. Unfortunately, I've been riding my 2 stroke lately and don't have room or the time to maintain 2 bikes. My loss is your gain! Front tire only has a few rides on it, the rear needs to be changed. Beta's are super reliable and amazing machines that rival KTM and Husky! 

      -Forks revalved by LT-Racing for 210# rider w/gear
      -Mylers oversized radiators and bulletproof radiator guards
      -Folding ARC clutch and brake levers (I have the stock levers as well)
      -3.1 gallon tank. (I also have the stock tank)
      -Seat concepts dual sport seat (also includes the stock seat with guts foam and motoseat seat cover)
      -FMF powercore 4 with silent core/spark arrestor. I've got the stock spark arrestor as well. Racing compliant!
      -Boano racing billet brake pedal with brake tip
      -FJ Fasst co. brake clevis
      -Billet chain blocks
      -upgraded steel oil pump gears- the plastic stock ones are prone to failure
      -Force accessories case saver
      -TMD skid plate (not pictured but will be on the bike)

      Extras:
      Acerbis X-factor handguards
      a few spare plastics pieces
      key switch with plug and play wiring
      extra tubes and rimlocks
      Printed and bound owners manual and service manual
      10mm billet bar risers

      It's a dirt bike so it has some cosmetic damage. Some chipped plastic and scratches on the swingarm. 

      Can send more pictures/info upon request

      I have a 1987 yamaha tt 225 that needs a new carburetor.  I've looked EVERYWHERE online and can't find an original.  Does anyone know a good replacement one I can put on it?
