Finally got the Gnarly Desert installed last night on my '03 220. All I can say is holy cow! It makes the 220 a different machine, it's 250-like as far as power. In fact, I'd say it's pretty close to my old ATK 260. Very smooth on the delivery, and it will definitely wind out now. Low end wasn't hurt at all, and mid to top is a huge improvement. I can't believe I waited this long to do this. I'm gonna have to relearn to ride this girl....
As far as fitment goes, I didn't have any of the troubles others have mentioned. It only needed some encouragement a couple of times, mainly when inserting into the exhaust port. I recycled the orings from the stock pipe. I think the biggest help was that I removed the PCII before install and had the mounts loose or removed until I got it all together. Be careful when tightening up the stock mounts, I twisted off one of the bolts that runs through the rubber grommets. Minor setback - luckily I had a bolt that would fit. (Aren't Dremel tools great!)
Jetting- 45 pilot, upped the main to a 148, with stock needle in the 2nd from the top position, AS 1.5 out. I had to up the main from a 140, as "she was a little lean" - resulting in a lean bog similar to what I had posted a month or two ago. Boy, would she scream though! Anyway, jetting is now spot-on and she's purrin' like a kitten.
Next up - 607 reeds and a new piston. I heard of someone locally who had a 220 piston grenade on them at about 500 miles.
