Question about 1979 Harley Davidson XLH 1000 Sportster
Have a 1980 sporty 1000xlh. sputters a bit when you hit high gear and get on it a little. stalls out pretty easy too. the bike has an S&S carb and is otherwise stock.

Hi Anonymous, check your intake seals and plug color, should be a light tan color, also check to make sure your accellerator pump is working, drop the bowl and check for contaminated or clogged jets, proper float level, depending on plug color you may need to re-jet. This of course assuming that your plugs and cables and timing are up to spec. Good luck

SOURCE: bike is stalling
Your going to have to determine if its an electrical problem or a fuel problem. Could be bad plugs a loose wire, misadjusted carb or contaminated fuel or a pluged fuel line. and actually a few other things including a bad piton ring. I would start with the cheap and easy stuff. Drain the fuel tank, clean the fuel filter......see if that helps

An 82 model Harley has the Shovelhead engine in it. These are good engines but they are aggrevating in that they are not as reliable as the later Evolution engines. I know a lot of people that have them and get good service out of them but they have to do their own work. Most Harley shops will NOT work on them. The reason is that they no longer have parts for them. You can get parts but they're aftermarket parts and sometimes don't work as they should. Most of the parts are made in Tiawan. If you find New Old Stock parts, they want a very high price for them.
If the bike has an aftermarket carb on it, it's probably an S&S Super "B" or Super "E". The original carb was a Keihen "butterfly" type carb, not the later version "CV" Keihen carb.
In short, the old shovel will give you lots of miles of riding but you must be prepared to do a bit more work on it than you would an Evo model. The old Shovels do have a good sound to them as well. It's a good bike for a person that doesn't mind getting his hands greasy every once in a while. If you don't want to do your own work, look for a good Evo or Twin Cam bike.

They go in the accelerator pump on the bottom of the float bowl. These are the check valves. Turn the float bowl upside down. There should be two screws left in the accelerator pump plate (one of them holds the float bowl to the carb body). Remove these two screws. Underneath this plate, you'll find a diaphragm and a large spring. Over towards the float bowl drain plug, you'll see two hole. One hole is deeper than the other. The deep hole is closest to the drain plug, drop the small spring into this hole and place one ball on top of it. Put the other ball in the other hole. Now, lay the diaphragm on float bowl over the accelerator pump well in the float bowl. Put the large spring on top of the accelerator pump diaphragm and place the plate over it. Work the plate around to seat the diaphragm in it's groove and install the two screws.
For a better view of what you're going, go to S&S's website. Click on "Tech Info", click on "installation instructions", and select "fuel systems". Look of instruction sheet #51-1012, installation instructions for E & G "shorty" carburetors. Download or print out the instructions which will include a complete parts breakdown, tuning instructions, everything you ever wanted to know about an S&S carb but were afraid to ask.
