:aj:

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.

re: 'I can't believe I waited this long to do this.'

You'll think the same thing when (if you haven't already) you:

1. Revalve/respring your suspension
2. Off that 33mm carb
3. Change the needle profile
4. Upgrade the reed block
5. etc.
6. etc.......

Yeah, it's like they say in dragracing: "How fast can you afford to go?".
Piston is in the works, as I don't want to be one of the unlucky ones....

Forgot to add...
I haven't even began to tinker with the suspension yet. New springs are a must-have, as I go about 185-190 without gear. The carb will be something I'll do when I get everything else, as the bike is already faster than I can fully utilize. Now, if I could just hit that fancy new lottery we have... :yeehaw:

Cool. Do you know Braahp and the boyz? Let me know if you want to ride Coal Creek and I will hook you up. Check out the Vol Riders website for upcoming events....

www.volunteerriders.com

Love to have you guys over for some KDX rides. Congrats on the new ride.

I don't know if I know them or not...I don't know their real names. Where is Coal Creek- up your way in Knoxville? We generally ride in Copeland's Cove in Livingston. But there is also some good riding in Monterey I hear. I haven't been there in years, so I don't know how it is up there anymore. Who else from the site lives near?

Knox, I have been riding my 200 Rev style, which kills me in the tight trails at Coal Creek... The trails that the Vol Riders have cleared, not the public stuff, are tight and nasty, IMHO! My 200 is not setup to deal with single track stuff. Bottom line is that I am going to have to convert the Rev 200 to a torque style 200 or move on to a four stroke. Truth of the matter is that my skills are not what they used to be, and the four strokes are MUCH easier for me to handle in the tight stuff. I rode a Vol Riders WR400 and fell in love.. I'm partial to blue anyway, growing up on YZ's.

I need to hook up with you and hit the open trials for some fun Rev style action... Then maybe I will keep the KDX and suffer through the tight stuff when necessary.

To turn my screamer (which I love to ride 125 style) into a twactor is going to require some additional funds... I've dropped WAY TOO MUCH into my KDX as is... It's easy to get carried away and build that dream machine that you can never get your money back out of...

I'm thinking a torque pipe, EG 225 kit with mid-low porting, flywheel weight, suspension mods and seat height adjustments are a must if I keep riding the single track stuff.

Let's me and you hook up in the very near future for some comparitive KDX test riding.... Maybe we can get Braahp and the other Cookeville guys to join us... Braahp has a nice setup on his KDX... :thumb:

All of the other club guys that ride my KDX say that it is prime time and that the proble is with the rider, not the equipment... :debil: I guess I need to shutup, quit wrenching, and get some darn seat time!!!

And yes, you are on the master distribution list now, but it will take a little while for the guys to update individual lists.

Welcome aboard Knox! :yeehaw:

John, Braahp is all over these boards, I would email him and introduce yourself.. Braahp is a KDX guru IMHO, and he really provided me with some good info when I got my KDX.. His bike is prime-time, one of the best KDX's that I have seen, and I have seen a ton at this point. Plus, he is experienced with TN trails and tracks...

45 pilot, 148 main, stock needle in the 2nd clip from top. Might be just a tad rich in the mid range, may try to go back to a 42 pilot. My elevation is just a little higher than yours, I'm guessing around 1000 to maybe 2000.

I'm in Hunstville, AL. Ever ride at Land Between the Lakes, KY, or Bankhead Nat'l Forest in Danville, AL?

I just bought a new 220 and am loving it.

Hey, one quick thought. I read a post from CanynCarvr in an earlier thread in which he said that running the MT VForceII made it to where he could use the Rev pipe in tight woods. If you haven't already done this, you may want to ping him and see how beneficial it really was. I don't remember which thread it was.

Best,
Greg
