Supertrapp IDS2 on '03 KTM Adventure

To those that are interested, I recently installed a Supertrapp IDS2 “quiet core” muffler on my ’03 Adventure.

Part number 611-96002 is, according to Supertrapp, actually intended for pre ’99 LC4, but by drilling a new hole approximately 7/16” above the existing hole on the “S” pipe mount, (that, or find a longer rubber mounting bracket) you can easily install it on a later bike with the stock turn signals. If no turn signals are present, no additional hole is necessary.

I currently have 8 discs installed. Jetting with the OEM BST40 carb has been changed from the stock 152.5 MJ to a 157.5 MJ in warm weather and 160 MJ in cold. The needle clip was moved down 1 from the 3rd to the 4th notch from the top. I drilled the vacuum piston ports out to .125” (1/8”).
I made a airbox side cover from 1.5MM carbon fiber plate with a port size of approximately 4 sq. inches. The bike runs quite well, sounds better than stock, but is not so loud as to attract unwanted attention on the street. Acceleration and throttle response are improved, both over stock, and with the IDS2 alone with no jetting or air box changes. Vibration is minimal and possibly slightly less than the stock bike. All impressions are based on riding at sea level to 1,000 above.
I have felt no reason to alter the low speed air or fuel jets, or the low speed fuel mix screw at this time.

For those having trouble finding main jets, they are the same as those used on the 42 HSR Mikuni sold as a performance carb for Harley-Davidsons. In other words, almost any Harley dealer or custom shop should have some.

At this point I feel that I can recommend the IDS2 for installation on a '03 640 Adventure. I will continue to make modifications and report any results.

Last note, that stainless is hard as hell, so drill slow, push hard and use drilling lubricant.

Regards,
Chris

I like Supertrapps. One for my KLX just came today to replace the old, rusty, nasty sounding Arrow that was on the bike.

Best feature is spark arrestor... Being able to tune the pipe is nice too! I paid $240; how much for yours?

Got mine at prts direct for $190 something

It's for a dr650 but sure looks the same as the pic of the ktm.
some one posted about small scratches, metal polish takes em right out and the super trapp looks like new again.

I'm a dealer... so lets just say, less than what you paid. But not by much, $240 is a very good price if what you got is an actual IDS2 with a "quiet core".

And a view of the carbon fiber air box cover. I am in the process of making yet another air box cover using 5 UNI filter pop-in air filter vents.

I'm one of those sick individuals that takes as much pleasure in wrenching and cleaning as I do riding. Sorry, I don't mean to set a bad example.

I can see things falling of better when they are clean, like me for example.

Now if we could just get Scotty to hustle it up with that low mount fender... I'd have a new thing to buy and polish!

I start out with a simple install info for a IDS2 and look what happens... dirty girls and clean bike abuse.
The horror of it all.

Flanny, if your bike gets all dirty, will Loadedagain lust after it and want to take candid photos of it in a short skirt?
