  1. Stock leak jet is a #60 A #45 comes in the GYT-5TJ93-69-01 Kit
  2. Anyone who installs the whole '07 AIS Removal Kit (GYT-5TJ93-69-01) is going to have a bike that runs too rich. You can call Yamaha techs at: 800-962-7926 and see if they have figured something out--but to date, nothing! Can't comment on the JD Kit. But the bike does run great just stock after throttle stop removal, intake (air) silencer, plus removal of gray wire from CDI unit. This is what we ran this March in Baja.
  3. The first GYTR Kit was indeed recalled. The new kit is: GYT-5TJ93-69-01 However, you might find, other than removing the AIS System, you will be happier with the stock jetting. Putting in the jetting that comes with the GYTR Kit seems to make the bike run very rich.
  4. The grey wire is located behind the L panel (by the air box). Take off the side cover and locate the plastic wiring harness w/six wires on either side. After disconnecting the wiring harness, carefeully push out the grey wire from the end that comes apart with a small screwdriver. Fold it, the grey wire, back and use black electrical tape to cover it up and protect the same. It's better than cutting and allows you to replace it should you desire to do so.
  5. No, you will need an '07 Kit. Yamaha recalled the first ones they put out. But you can now purchase the Yamaha Technology-Racing AIS Removal Kit/YPAD Competition Kit, GYT-5TJ93-69-01 for about 50 bucks. I would not recommend that you use the #175 main jet that comes with it. Consider going down to a #168. You also might consider a #48 pilot jet instead of the #50 that comes with the kit. Good luck!
  6. The part kit you are looking for is: Yamaha Technology-Racing AIS Removal Kit/YPAD Competition Kit #GYT-5TJ93-69-01, about 50 bucks. You should consider going down to perhaps a #168 main instead of the #175 that comes with the kit--it, the #175, is too rich. Also, I have noticed that others have used a #48 Pilot jet instead of the #50 that comes with the kit--#45 is stock.
  7. Just purchased two 2007 WR450's Worked great in Baja with following adjustments: removed small tail pipe leaving spark arrestor, adjusted fuel/air screw out from lean, removed snorkel on air box, replaced throttle stop, and that was it. Bikes ran perfect. We changed oil after first ride and replaced oil filter with Scott's steel unit. Will take off AIS. Yes, suspension if soft, but nice! NOTES: Check your air-filter plastic cage--early 2007 models have small hole in center that can suck in dirt. Replace at dealership or plug hole with silicone. LED rear tail light w/3rd wire can accomodate brake light function for converting to street legal.

  9. My son and I just purchased the new 2007 WR 450F's. And I must say they run great stock. We removed the stinger leaving the spark arrestor in place and did the YZ throttle stop. That was it! No, we didn't cut the grey wire at the advice of our service rep. Not sure how it is going to run in Baja in two weeks when we venture down there with new bikes. Yeh, it has the 162 main. Will tell you more after Baja. Pablo
