Question about 2000 Harley Davidson XL 1200 S Sportster Sport

2001 XL1200S Cuts out and dies at highway speeds for a moment

Riding home from a poker run yesterday the engine light would come on and the bike would just start cutting out and backfiring at speeds about 40. I pulled over and the oil light came on too. I checked oil and level was fine. Re-started the bike and it would idle fine and engine and oil light were off. Hit the road again and everything was running fine. Then on the 25 miles left to get home I would feel it start to sputter, the spedo would drop to 0 and the odometer would turn off and the engine would shut off. This would only last for less than a second or two. Then everything would be fine again and compression would get the engine running again and everything would come back on. The bike only has 4800 miles. The guy I bought it from last fall had it stored for a few years. And it was not ridden much. I also just put new hand grips on it. So I am wondering if I am having problems with the kill switch

If it was stored with fuel in the tank:

1. The fuel filter should be replaced
2. You may to replace the fuel delivery system coming out of the tank
3. Remove the plug in the carb and reset the idel mixture

I just bought one store for 6 years - my issue is the bike will n ot idel but runs on the road like a bat out hell.

Did you put a new battery in it? If not have it load tested and replace if needed. Check the grounds and make sure they are clean and tight. Check the stator by going to the plug on the right front down tube, with a muti meter take a reading with the bike running on the side that goes back toward the engine, I forget the values but you should get a reading at idle and then as you rev the motor the reading should climb. If all of the above check out OK the problem will be your voltage regulator.

I would suggest not making any changes until you find out the problem. especially if the bike was running ok prior. Was the bike sitting for the winter? did you use any fuel stabilizer? Change fuel including draining carbs. Check your air intake passages for spider webs, any mouse nests,... check air filter. change your spark plugs , especially if they look black. The condition of the old spark plugs will tell you a lot. Black indicates running too rich. Whitish or next to nothing indicates too lean fuel mixture. Tanish color is perfect.

It sounds like a fuel flow restriction somewhere. Sure, it'll start every time and idle for a while but take it down the road a bit. If it quits, I'd suspect that for some reason it's not getting fuel to the engine from the tank. Loosen the fuel cap, the cap vent may be bad. The vented cap the right side tank cap. If it's fuel injected, it could be the fuel pump or something. It sounds like a fuel problem to me.

Good Luck

Sounds like you are fouling your plug.Some possible causes make sure you air filter is clean. Correct gas oil mixture.How the bike is being use Trail riding/freestyle.This bike in stock form will foul plugs if it is being used as a trail bike.If everything is good air filter/gas-oil. Then you need to do a spark plug reading. This will determine if you need to rejet the carb. Hope this helps

1996 Suzuki Savage 650 backfires on cutoff


I had the same prob with my 97, It was not the head gasket but the O-ring on top of the head. Replaced the O-ring and has been running good for a year now with no backfire. Hope this helps.
