Picked up a YFZ
I just picked up a yfz from the local dealer and have a couple questions. I already ordered a Jardine full exhaust and I need to know what intake I should get? I ride in very dusty areas but no water. Also I was wondering if anyone in VA could give me a base for jetting. Does the pipe come with jets or do I need to buy a jet kit?

You can either get the ESR airbox eliminator (if you don't ride in wet or muddy conditions), or get the Pro-Flow set up that still utilizes the stock airbox without the lid. Use the outerware if you get the K&N filter, or just stick with a foam filter if you aren't comfortable running a K&N in dusty conditions. I've heard pro's and cons of both.
I don't think the Jardine comes with jets, but I have never heard of whether it does or not.
Just get a
45 pilot
Put the stock needle on the 5th-6th clip position, or the YZ needle on the 4th clip
170-175 main
and adjust the fuel screw accordingly.
That should get you pretty close. [img]i/expressions/face-icon-small-wink.gif[/img]

I'd say check it within the first 30 to 50 hours at least to make sure things aren't moving around on you. These are pretty high strung motors, and you don't want to go too long without at least checking them.

Blazing, I just picked up an 05 YFZ450 myself about 4 weeks ago and also live in Virginia.The elevation where I'm at (Marion) is a little over 2000 ft. So far I've added a DG Xcellerator Stage 1 slip-on, K&N filter w/Outerwear, removed airbox lid, Big Gun CDI, 13 tooth front sprocket and 39 tooth rear sprocket.I'm running a 168 main jet and the quad seems to like that.
The instructions that DG sent me with the slip-on suggested running an aftermarket air filter with the airbox lid off and running a 170 main jet at sea level.
