    WR450F 2006 larger tank

    How did you make out with your replacement tank for your WR? I'm ready to do the same and am also hearing you need to replace the shrouds with the Acerbis tank which is contrary to what I'm reading here. Any clarification would help, don't want to buy shrounds if I don't need them.

    Here is a good guide to disconnecting the gray wire: http://www.thumperfaq.com/gray_wire.htm

    Yes, the gray wire is in the harness on the right side just behind the gas tank. My understanding is that when it is cut (or the pin is pulled out and taped up like I did) it puts the engine response on the YZ power curves instead of the limited ones to meet emission restrictions. You removed the Air Induction System (AIS) crap too right?

    The needle inside the body of the carb is only adjustable in the sense that it has a lock-clip on the high end to change it's length. Are you talking about an adjustable throttle mixture SCREW that you can change on the outside of the carb? If so, that is not stock and they added that as well.

    It's adjustable in length but I think the gyt-r needle in their AIS mod has a different taper at the tip which is the YZ needle. I did many mods at once so I can't tell you how much the needle replacement is contributing to my significant better performance than stock.

    I have not read about how well this insert works compared to stock. I removed my 2006 stock insert and opened up the exhaust probably as much as the GYT-R does so I'm skeptical that it will get you that much of a "performance increase". Have you ridden you bike with no insert? It does look pretty sharp though so maybe it's worth the $40.00 just because of that.

    Excellent, I knew it was buried in here somewhere, thanks for the pointer.

    I purchased the GYTR AIS removal kit from the Yamaha dealer for my 2006 WR450. I got up the nerve to do all of the mods except the carb needle, pilot jet, and throttle stop mod. I can say that the other mods have helped tremendously with the cold-start problem I was having and there is a noticeable power increase with these alone. The directions for the carb mod are not that clear and I don't want to start these mods if I can't complete them. Does anyone know of a post that details the steps for the needle and pilot jet replacement? The big exploded views of the carb in the user manual don't give me any more confidence either!

    Great information in these posts, thanks to all. I'm a newby and just bought a new 2006 WR450. My concern at the moment is cold starting the bike. I have yet to start it using the electric only, I always have to kick start it. Once it's started, it runs (what I think) is fine. I've read about all the mods I can do down the road but what is the easiest way to make the mixture richer and get this puppy to start with the magic button? The local dealer says they can do something for ~$40.00 but it would be nice to do it myself.
