Question about 2000 Harley Davidson XL 1200 S Sportster Sport

2 Answers

1998 Sportster XLH 1200 seems too smoky. Carb, including jets were checked - ok. Not visible smoke, but just gives rider that exhaust smell even after short trips. 14 k miles and recently serviced. Is this just typical for sportys or should I look for some solution? Information required is closest to allowed entries.

Is this a recent development? Or has it always left that smell? I had an older Sporty, that I ran too rich for years, it left lots of black soot on the inside of the exhaust tips, and a very pungent exhaust smell on your person. When I went down a couple jet sizes, it got much nicer, and ran a little better as well.

As you ride, there is a low pressure zone created behind your back. Exhaust gases from the bike do get trapped in this low pressure zone and this may be causing the problem you're talking about.

Now, the jetting can be correct in your carburator but still the accelerator pump could be a bit on the rich side or if you're "blipping the throttle" too much while riding, this causes that "running rich" smell. If you are concerned about the mixture, put your bike on a dynometer that has an exhaust gas analyser.

Recently purchased a sportster 1200 xl low rider 06 plate. Which is great in every way apart from town use, I find that once the engine has got warm I am having to continually blip the throttle to stop it...


Regrettably, it is a "norm" for an H-D Sportster but it's fixable. The engine is jetted very lean in order to meet EPA emission standards. The lean mixture is what causes the spitting back through the carburetor and poor idle qualities of the engine. You can improve the low speed and idling characteristics of your engine by going up one size on the low speed jet and readjusting the idle mixture. If you can do this work yourself, let me know and I'll give you the instructions on how to do it. If not, take your bike to a performance oriented shop and talk to them about it. If they have a dynometer and an exhaust gas analyzer, they can fine tune your bike to where it runs like it should.

Good Luck & Ride Safe

Cherryvalleytoolmaker@msn.comHow do I get more power out of a 2003 XLH-883. Can you do jet work or purchace a new carb that is adjustable?


depending on what you want to spend , what you can do yourself it varies.

new hi-flow air filter and exhaust will add a few horses but you will also need a carb adjustment to go with that
new cams will also add to your output

I have a 1996 883 Harley Sportster with a S&S carb (E) . When ideling its ok , but as soon as you try to excelerate it cut right out . Could it be the excelerator pump ?


Suspect items are the float level, accelerator pump, acc. pump inlet and exit check valves, off idle circuit, and main jet circuit. Be certain that you have no intake leaks.

I have a 88 sportster 883 /1200 is what I was told .How can I know or tell for sure a kit was put in it ??without tearin it down ..It now also has a s&s short E carb and samson double tube exhaust...


There was a way the drag strips used some sort of instrument to determine the displacement of an engine without a teardown. Seems it was called a P&G tube or something like that. I've never seen one. The only way I know of telling if your engine has be bored to the 1200 cc. piston size is to take the head off of a cylinder.

The S&S carb is an old design but it's simple to tune, that's what most people like about them. The CV type carbs are much better but American riders don't like them much. Although Mikuni is making headway under the Screamin' Eagle trademark.

Now, if you bike was orginally and 883 and it was converted to a 1200, there are two ways of doing it. One, was to buy a complete kit with pistons and heads. The other was to bore the original 883 cylinders and use the original 883 heads but the pistons had to be special drop top type pistons to keep the compression to a reasonable amount. The combustion chamber of the original 883 heads are much smaller than the chamber in the 1200 head. If you don't use the special pistons, you won't be able to keep head gaskets on the engine. Wiseco makes the pistons for the conversion.

As long as the engine is running good, don't worry about it.

"Backfiring" is a pretty broad term depending on where you live. Some people refer to backfiring as popping from the exhaust while others refer to it as the engine spitting through the carburetor.

I'll assume that you're talking about popping out the exhaust pipe. If it does this after you rev the engine and it backfires on the way back down to idle, this is typical of an exhaust system sucking air. The mixture is extremely rich under these circumstances and will not ignite. But, if your exhaust system is sucking air, it combines with the fuel air mixture already there and bring it to an explosive mixture thus the backfire.

You can check you valves but I've always found that if the valves on an Ironhead are too tight, it's extremely difficult to get it started due to the low compression on that cylinder.

Check you ignition timing and points setting. Also, what kind of condition is your mechanical advance in the distributor in? I'm assuming this is an XLH model and not the magneto equipped XLCH.

What type of carburetor is on the engine? Hopefully not the original Tillotson that it came with. If it's an S&S, the low jet should be a 28 and the main jet a 66 to 70.

1994harleydavison 1200 sporster sat a long time flushed tank and carb idl fine no hi speed after 3000 rpm ?


Sounds like your high speed jet is still stopped up. You didn't tell me what type of carb you have on the bike but what you've got to do is the same. You must remove the float bowl, remove the main jet, and clean it out. Also, clean the very bottom of the inside of the float bowl.

Flushing a carb will not clean the jets. The reason is that fuel must be able to flow though the jet in order for any chemical additive to clean it. If no fuel flows through, no cleaning action is taking place. That's why you must disassemble the carb and manually clean the small holes in the jets.

If you need more specific instructions, I need to know exactly what carb you've got on the engine. Good Luck, Steve

Took apart carb cleaned and now there is no mid or high range


did u install new gaskets, the engine might be sucking air from outside the carbs. u can use a propane torch (not light) spray a little around outside of the carbs, see if engine sounds different, if it does... leaky gasket.. u might check there is no unplugged vaccum hose.

If you are not running an open or free flowing exhaust go back to the stock size jets but use the DynoJet parts instead of the stock.
DJ jets tend to run bigger than oem jets
