OLD Question First 640 ADV accessories

I just read the thread about what to get first for your KLR, well, I would like to address that for the KTM 640 Adventure.

If you had a brand new one, what would you get first? or what needs to be changed first?
ahh budget.. $1000

Electric outlet..$25-40
GPS mounting.. $70-100
GPS unit.. spare no expense, get the best there is, Garmin 276C.. $600-800

Get a GPS unit that gives you routing and estimate time for arrivals, that way you can give yourself good estimate of how much time you want to spend riding. Personally, that feature on my GPS makes me ride longer than I should sometimes.

Depends on how and where you intend to ride it, and what kinda stuff blows your skirt up.

Basic stuff is:

Re-jet.

Air box side cover

New muff or mod the stocker

Renazco seat (boejangles)

Loadedagain or similar risers (if your 5'10" or better)

Adjust damping for weight or get suspension reworked if your heavy

Factory service manual

Grips


Other stuff:

Panniers

GPS & mount

HID lighting

Better tires (if your doing lots of off-road)

FCR carb

Alternate gearing (if your doing lots of off-road)

Mirrors (stockers are lame IMO)

"Bigger" pegs


Lots of other odds & ends... personal wants and desires... your perception of requirements... some objective, some subjective... even some regional stuff.

Thanks, can you direct me to a thread that tells how to do the re-jet, air box and Muff?

i took things from a different angle because of warranty... mine is 5 years. i couldn't get into dickin with the engine as far as replacing silencer or mods because the warranty doesn't allow it... and if she cavs inside five years i want them to pay the bill.

so i started outside.. panniers came with the bike, but to me are essential. since i build and sell risers... i have a set of them. i also messed with the suspension to make the bike more roadable with my 225 pound ass on the bike. as cat2000 says a gps was a cool adder. started with a little etrex which was neat, but now have a garmin 276c.

i was worried about the subframe with the added weight of the panniers and gear, so i custom made a stronger one... fine if you have fab ability, but really expensive if you have to have someone else do it.

little things like the tripmaster switch... auto fork bleeders... canisterectomy... maybe i'll add more later.

Manufacturers, in fact, cannot prohibit use of aftermarket engine stuff and then withhold warranty repairs..........I 'spose this point is up for debate, and even think I saw a thread on it somewhere here.....

Canada has different laws. Sometimes not enforced, sometimes non-existent.

You are partly right, adding fancy mirrors will not void engine warranty. Full Akro exh. sure will.

Well, seeing as how you're going to be doing all that typing anyway...the '02 I picked up Sunday is bone stock. I want to add the open airbox cover, rejet, and open up the stock exhaust. I must be the dumbest sonofabitch around, because I searched the forum and couldn't find a thread covering modifying the stock exhaust, and jetting to go with it.
Love ya - mean it.

As promised...

OK… here we go. As I have never seen a 2005 640 Adventure, we are, for purposes of clarity, going to assume it is the same as ’03 - ’04.

1. Main jet.
You should have a 152.5 as stock. Remove this (the bowl cap is a 17mm as I recall) and install a 160 main jet; pay attention to the spacer that comes out with the jet. This is only a starting point, you may go up or down 1 or even 2 sizes for your conditions. They are the same main jets used in Mikuni HSR carburetors for Harley-Davidsons, which makes them available at just about any H-D dealer or custom shop.

2. Removing the vacuum cap from the carburetor.
Remove the fairing and fuel tank, you don’t have to remove the dash, simply tie the “ears” up to the handlebars.
Remove the 2 screws holding the cap on while lightly holding the cap down. Remove the cap, and gently remove the vacuum piston/slide assembly. Remove the spring and push the needle up and out the top of the slide.
Note the position of the parts; refer to your owners parts catalog for correct position.
2.a. Remove the clip (do this over a large table, maybe with a white bath towel on it… just in case you “loose” the clip) from what is I assume will be the 3rd position from the top and relocate it to the 4th position.
2.b. Obtain a drill bit, preferably a longish one, .110” to.125” in diameter and drill out the two vacuum ports in the slide, on either side of the needle hole, to the drill diameter. Drilling from the top is slightly better because the surface inside the slide is square to the ports; the outside has a radius that requires you to have a bit of drilling talent.
2.c. That’s all the mods… you can reassemble the carb. You can use your finger to help guide the needle back into the needle jet in the carb body, then insert the spring. Be careful when reinstalling the cap that you do not pinch or distort the vacuum diaphragm. Don’t over-tighten the cap screws.

3. The air box is easy… either buy or make a copy of the KTM high flow air box side cover. Do not remove the snorkel on top the air box… unless you plan to run a 41mm Keihin FCR and a complete Akrapovic system, or it’s equivalent.

Here is one I "hacked" out of some 1.5mm carbon fiber plate... actually cost more to make this than go buy a KTM one.



4. Stock muffler.
Remove the Supertrapp spark arrestor discs and end cap. Obtain a 1.5” hole saw (might be 1.375"... but I think it's a 1.5" ), find a wooden dowel that fits tightly in the center hole of the mechanical baffle… you need this to help center the drill. (Vrago’s bitchin’ idea )
Core out the baffle tube with the hole saw. A tube of about 6 inches in length comes out when the hole saw cut thru.
Reinstall the discs… the bike probably comes with 10 – 12 discs stock… you can add up to around 16 to suit your personal sound meter, but as I recall, 10 – 12 is more than enough for most folks.
A bike that sounds good is great… a bike that deafens citizens is not so good.

That’s it… I hope.

Creeper

Quick addendum...
While you have the tank off... this is a good time to remove the stock evap cannister and hoses. Just run a regular gas cap vent hose into the hole in the fork stem nut... just like 99.9% of the dirt bikes, or get a spiffy one way valve from e-line... or whatever.

E-line one way vent

Your mods are almost identical. You start out with a 142.5 main jet, so you'll be going to a 152.5 as a starting point. If anything, it may be a bit rich.
Some folks with pre '03 LC4s have felt the need to richen the pilot circuit. This can be done by installing a richer fuel jet or a leaner air jet. You will have to decide for yourself if this is really needed.
