There was a post a few days ago in the new members forum that I posted a bunch a few good mods and tips in. So I figured I should post em' here to compile them so everone with an SMC can see. If anyone has anything to add, please do.
Coal Canister and SAS removal:
The coal canister and the SAS makes no difference in performance, but it does remove unwanted crap from your bike. The SAS (the secondary air system) does eliminate the backfire on decel that our bikes are plagued with from the factory.
Coal Canister -The coal canister is located under the seat. It looks like a big black cylinder with hoses running off of it. You can basically just pull the canister and remove all the hoses that are connected to it. Now just run the tank ventilation tube into the frame tube under the handlebar. Or you could always go with one of those cool aftermarket caps with one way check valves, but it's not necessary. You will also need a small vacuum cap that you can usually get at automotive stores. You will cap the now open port on the airbox right above the rear brake fluid resevoir. You don't want air getting in their as it's unfiltered air.
SAS(secondary air system) - Before you even start your gonna need these items:
-a short 6mm bolt to plug the hole on the intake side of the carb
#33-right side exhaust flange - 58036040100
#34-plug bore - 58336024000
#35-copper washer - 58436054000

I have the part numbers for all those parts, but I have to post them later because I don't have them on me. You also have the option of finding a left hand frame plug to plug the hole that will now be on the right side. I've been running mine without it for a while with no problems. The SAS is located to the right next to the right side exhaust port. It's the big mechanical looking thing in the second picture of the link. Once you get all the parts then you can just remove the exhaust springs. Unbolt the SAS and remove all the hoses that are attached to it including the large one that runs into the frame. After you remove the large hose put the rubber plug back into the frame. Now move the header so you can replace the exhaust flange with the new one that doesn't have a bracket on it. You will also have to remove the copper ring from inside the little port between the exhaust ports. It's kinda hard to get at, but you have to replace it with the new one and also plug it with the new plug you got. Now put the exhaust back together. You'll have an open port on the cylinder intake side. That port screws out. Take it out and replace that with the 6mm bolt. I hacked mine down to make it the same amount of threads that are on the port. Make sure you put a little thread locker on that bolt.
The two pictures are the bike with the SAS and the coal cannister removed. Here's some pictures of the parts on the bike: http://ktmtalk.com/index.php?showtopic=113887&hl=right side exhaust flange&st=15, http://ktmtalk.com/index.php?showtopic=67592&hl=sas+removal. All together both jobs took me about an hour to complete. It may sound complicated, but when you have all the parts it's a snap. If your intimidated at all about removing these parts don't be. They literally do nothing for engine performance and has no impact on how your bike will be tested when you get it inspected. They're put there just to appease the EPA before the bike comes into the US. Good luck.:thumbup:
