Re-jetting carb
I just put a set of SEII on my wife's 06 -1200 Sportster.
Did not change air cleaner or re-jet the carb. The bike runs great, actually better than when the
stock exhaust was on.
My question is, how hard is it to re-jet the carb, and how do I know what size jet to use.
I would like to to this myself as the Harley dealer wants 1 to 1.5 hrs labor, plus parts.
Also it would be something good to learn.
Thanks

RE: Re-jetting carb
03,
It's real easy on the 06. Remove the entire air cleaner, work the carb out of the intake manifold, it's just plugged in with a rubber gasget.
All you have to do is tip the carb up some and with a 1/8" drill, drill out the aluminum plug covering the idle mixture screw, be gentle as you don't want to go past the plug and garf up the mixture screw. After you have drilled the hole, take a sheet metal screw and screw it into the hole, grab the screw with a pair of pliers and gently work it out, it's easier than it sounds.
Gently turn the idle mixture screw to the stop, I repeat GENTLY, then back it out three and a half turns.
Now remove the bowl, it's held into place by four screws, have a rag under it to catch the gas that will come out, not much just what's in the bowl. remove the low speed jet, you will need a narrow #1 screwdriver, not one with a tappered tip, it has to fit up into a hole.
replace the jet with a #45.
Reassemble, before pushing the back into the manifold, check that the rubber gasget is in place. Coat it with dish washing soap (liquid) to help the carb slide into the manifold. replace the aircleaner, ride.

RE: Re-jetting carb
rejet kits I have seen provide the written directions to walk you through the change. Pretty much as was described to you. It's a bit easier I think to pull the carb completely off, which means taking loose the enricher from the opposite side....then work at your bench.

RE: Re-jetting carb
Oh lord, don't waste your money on a jet kit. All you need is a no 45 jet. It'll set you back less than $10. Go to sportster.org they have really good directions on what to do once you have the carb loose. Oh you don't need to disconnect any of the hoses/wires from the carb, just follow the advice of DC above. All that holds the carb onto the manifold is the a/c bracket connected to the crankcase breather bolts and the carb. So once that is removed, you can just slip the carb out of the manifold, and tilt it up enough to be able to see underneath. You shouldn't have to change the needle, therefore eliminating the need to gain access through the top of the carb.
I just jetted my 883 this afternoon. If it hadn't been for the usual 8 trips to the hardware store for tools I didn't own, and parts omitted from my air cleaner kit (I changed it completely) it would have taken me, a completely unmechanically inclined woman, about an hour and half. If all you are doing is adding the SE kit, you shouldn't have to worry about needing odd tools and omitted gaskets!
The only thing I'd add about removing the mixture screw plug, is I went at it mostly with a 5/32", for about 1/8th inch, then switched to a 1/8" bit. Drill real slow, don't press down, just let the turning of the drill eat away at the plug. Check it every few seconds. When I saw a what looked like a pinhole form, I stopped and screwed a sheet metal screw in a few turns till it bit good, then took some pliers and pulled it out. You have to be that careful, the screw is right under the plug and if you damage it, you'll be SOL.
