New A/C and Drag pipes time for rejetting
I have had the drag pipes and am popping on a DK CUSTOMS HiFlow 587 AIR CLEANER K&N FILTER STAGE 1. I am a noob to messing with carbs but I am sure that I will need to rejet this thing. My question is what kind of jets , how many are in my carb and are the jets all i need to replace or should i be replacing other parts in the carb? Also what size jets for that setup? Thanks for the help

Sounds like you should just start by getting a main jet the next size up from what is already in there so you get a little more gas. It's impossible for anyone to tell you without having the bike in front of them but most of the time that's all it takes. I had a Honda a couple years ago which didn't allow you to mess with jets so I bought a set of micro bits (almost like dental drills) and kept honing them out till it ran right. Keep checking your plugs for color. If they turn black and sooty, you've gone too far.

If you get down on the ground and look up at the bottom of the carb, you'll see 4 philips type screws. Take those out, and remove that bottom cover, or bowl, and you can access the jets. You'll want to drain the gas out of it first so you don't spill on yourself, I just shut the fuel at the petcock and let the bike run until it quit. Jets go in and come out with a flat screwdriver, don't loctite the new jet in.
Some guys will tell that removing the bowl with the carb still on the bike is the wrong way to do it, and with a 2001, depending on how many miles you got, it might be a good idea to take it off and clean it up. Maybe replace those seals where the carb goes into the actual engine.
I did mine quick and easy with the carb on the bike, bought a 45 jet for $8 and replaced the stock 42 that was in there, and it's been fine. You'll also need to look up how to adjust your idle mix screw. When I did mine, everyone was telling me a good baseline for a 1200 was a 45 jet and 2.5 turns out on that mixture screw, so I tried that and never adjusted it since. It runs strong and the plugs look good. If it ain't broke...
