Question about 2000 Harley Davidson XLH Sportster 883 Hugger

3 Answers

I have a 1999 Sportster Hugger that burns a lot of oil and blows out a lot of white smoke when I first start it up. After it warms up it does not stop but it smokes a lot less. I have changed the oil and spark plugs numerous times but the problem persist. When I remove the plugs they look black, I believe it is a timing issue, if it is can you let me know how it can be adjusted.

The problem is not timing. The problem is the piston rings not working as they should. Chances are the cylinders need to be re-bored or honed at the least. New pistons and rings will solve only the constant smoking. The smoke when starting is oil leaking past the valve guide seals. When the pistons and rings get done, get new seals in the guides or totally new valve guides. Have the vale faces re-lapped as well. When you are done, you basically have a new engine. Change oil more often. Dirty oil is what caused the problem. Please rate my answer. Thanks!

Your valve guids are in need of repair. There is too much clearance between the valve stem and the guide and this is allowing the oil to pass through to the cylinder. The engine will spit out white smoke until the valve and guide heat up and form a better seal. I would recommend having the valve guides sleeved with silicone/bronze sleeves instead of pressing out the old and pressing in new one guides. Any time that the spark plugs are coated in oil or fouled (black), this is caused by faulty heads. Your timing will not cause the engine to burn oil.I hope this helps.

    Rebuilding a motor is a blanket solution but to fix the actual problem and not repair unneccessary engine compontents is the point of this web service. I had the same issue and the correct fix was to repair the valve guides. Ask a professional head builder near you for some unbiased advice.

X-Type Jaguar blowing white smoke

White smoke is steam. Blue smoke is oil, Black smoke is too rich a mixture.

Check your water to see if it is going down. Check your oil to see if there is any water in it.

some cars will steam when warming up as condensation which forms in the exhaust is burning off.

White smoke is usually coolant burning. Could have also been a large buildup of water/moisture in the exhaust.

CEL blinking smoke coming from exhaust, rough idle

White smoke is indicative of burning coolant. Gray smoke is burning oil.

Have a compression test done which will often give an indication of evolving head gasket problems. If the coolant level is going down, and there's no obvious leak, its a head gasket.

White smoke

White smoke is usually a sign of the engine burning coolant.
You may have a gasket leak where the coolant is leaking into the cylinders when the engine is off, and you are burning it out until it warms up.

99 Grand Am Smoke Exhaust

I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

What would cause my 1999 sportster 883 to have white smoke coming from the exhaust?

sounds like it could be piston rings allowing oil to get into the pistons then burning out causing the white smoke stand behind the bike when its running and put your hand over the exhaust if there is we specs of oil on your hand or even a tissue sheet would do then afraid this is the piston rings and sadly not a job for the faint hearted mechanic hope its not best of luck

Blowing light smoke and burnning engine oil

Blue smoke is usually oil burnig related. White smoke is due to coolant mixing with the oil. (Head gasket leak) You should have the coolant system pressurized by a garage to see if your system holds pressure. This test will tell a lot. Coolant in the oil is a big problem.
