If I drop in an K&N do I need to re-jet. Dealer says I don't but...

I would. Dealer is stupid. Try going up a jet. More air=more fuel. while your at it remove the intake snorkel that is on the bottom corner of the front of the airbox that sucks air into the box. This should help as well with popping issues you might run into. Why dont you try using a K&N clamp on vs. the drop in? Costs are pretty close but you would probably be happier with the clamp on. You'll have a hard time recovering after getting ripped a new one with the clamp on. To top it all off you can then remove the whole airbox, and ugly snorkles plus it looks pimp from behind cuz you dont see an ugly ass black airbox. You dont like to see ugly backsides now do you? So just do as I say and you'll have an attractive little baby to ride around and look at from behind Hit these pee holes up for a K&N clamp on. http://www.hyperracing.com/product.asp?prodid=88-000

Ya see foo. Looks pimpin' dont it?

**notice the little bling bling spot(the sun was hitting a part of the wheel) where the airbox used to be? You can have one of those too. That **** be blinding me** Thats free once you take the airbox out.

What elevation are you at in Ottawa? That has a lot to do with whether or not you have to rejet. I didn't rejet up here at 4500' in Reno. I tried it and it slowed me down, so I went back to stock jetting.

Now, when I run the clamp on filter like John has in his photo, I do have to jet up to the 160 main jet and 50 pilot jet. However, I haven't been happy with how the quad tends to stumble in the midrange when I apply throttle, so until I decide what to do about it, I went back to the drop-in and stock jetting.

hey Rob I know you already know this but your stumble in mid range should be a needle adjustment. As 1/4 to 3/4 throttle is controlled by your needle setting. I experienced the same problem while playing with different jetting and ended up having to place my pin on the 4th clip down from the top to get the problem to go away . I'm not jetted as high as I could be (157.5) but she sure hauls now. Will probably be at 160 or there abouts when I'm done. I ride primarly at the oregon coast. Hope I'm not being to lame in responding to a problem but I'm learning to tune 4 strokes by trial and error. Been riding 2 strokes for years and decided it's time to move into the new century. good luck and thanks for the great site, it's been very helpful
