No sweat. Screw the idle mixture screw in until it "bottoms out". Do not tighten or you will damage the screw. Back the idle mixture screw out about three turns. Install carburator and check for proper operation.
When you get the bike running, allow it to warm up and then adjust the mixture for highest smoothest idle. Set idle speed to about 1000 rpm with the throttle stop screw.

SOURCE: I want to put a new battery in my 2004 harley

First check the manual that came with your motorcycle. I dont understand that you have to do anything to the exhaust. Remove the battery cover and you will see the battery. Take off the support bracket. Undo the positive and slide out the battery. It should slide out just enough to undo the bolt holding the neg cable onto the battery. then just slide out the battery. look at the neg cable where it is mounted to the frame. You should be able to see it peeking from the left side through the frame to the left side. I am only just replacing the battery on my 2004 1200 xl so if it only has 900 miles on yours you may want to trouble shoot before you do the deed. there is just enough room to charge the battery without disconnecting the cables using small alligator clamps on your battery charger. just slide the battery out as far as it will go and hook it up. I hooked up an accessory electrical plug for my bike and i was able to charge my battery with a tender. I just replaced the alligator clamps with a cigarette lighter type plug and stuck it into the accessory plug and it charged it with no messing with the battery. Just think it through and you can make it work. disconnecting from the frame is alot of work to feet the cable back through after you pull the battery out. good luck

SOURCE: if I change the head gasket on my 1200 harley should I do the base gasket too?

YES, you should always do base gaskets when you do head gaskets, the reason is, when you untourqe the head bolts, you do disturb the base gaskets, you have just releived the pressure on them needed, once you do that, its not worth risking it. you should never untourqe that gasket and retourqe it.

Testimonial: "I did decide it would be better to do the base gasket while I was there. I also changed the rings while there. Thanks for your help. "
