Hi, Virgil and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

I have 1998 FLHTPI when i slow down at to stop engine light comes on and bike shuts off cold idle is fine when this happens rpms drop below 1000

It sounds as if the idle system is blocked or restricted. If the fueling is injection then you need to get the bike on a diagnostic machine and check the fuel map and the fueling sensors. If it is Carbs- then you need to clean the carbs, the idle jets are very small and block easily over time. I hope this helps. Or you could just keep the revs up along with the front wheel, and save rubber(he he)

I have a 1980 kz1300 that starts up but mis fires any ideas?

Basic tune up. May need the carbs cleaned, new plugs/wires, and ignition system gone over, including points cleaning/replacement (if equipped) and checking for proper operation of alternator charge coil and rectifier/regulator.

Ensure battery is properly charged.

Can't get 1980 Harley Sportster to idle. New

My guess woud be that you either have not got the timing set correctly or something to do with the intake/ carb.

Since you say you replaced the advance weights, this tells me that you removed the breaker plate. I hope that you replaced the entire mechanical advance unit unstead of just the weights. The problem is that the pivot pin wears and replacing the weights does not replace these pins. I always use the needle bearing equipped units.

Now, to check the timing, connect a timing light to the front cylinder and start the engine. Remove the timing plug from the left side of the engine and shine the light in the hole. Bring the engine up to about 2500 RPM. You should see a "dot" in the middle of the hole. If not, you'll have to move the breaker plate to change the timing.

Intake and carb. I've seen brand new intake clamps with new "rubber bands" leak. I always pressure test them. To do this, you must make a plate that replaces the carb and bolts on to the intake. In the middle of this plate, there should be a hose nipple. Rotate the engine until both intake valves are closed and apply about 5 PSI pressure to the intake. Spray soapy water on the intake and clamps to find the leaks. Once the leaks have been stopped, work on the carb.

If you're using the original Keihen carb, you'll probably find that the slow speed jet or the idle port is plugged up. I'd disassemble the carb and soak it in carb cleaner. Make sure all the air and fuel passageways are clear. If the idle mixture adjusting screw is frozen up, trash the carb and get another one.

Good Luck

You need to go thru the carb.s again. Looking closely for very small holes in any of the jets. Next will be to sync the carb.s together.

1979 KZ 1000, with four mikuni vm26ss. Pilot Fuel Screw located on the engine side, opp. air filters. In or out for air? Category section would not let me enter proper info.

Those arent ajustment screws as the screws are in front of the float bowels in the center of each carb and they only trun a quarter turn unless the locks have been removed they'll keep turning with the blows off and they are likly to be dirty. Remove and wash out with carb cleaner and compressed air as all the other jets do too. The ones in the air horns too. Air screws are out 1 1/2 turns if the motor is in good shape' The screws in the sides are plugs that let you hook up your vacume gauges to sync the carbs. with all the vacume matched up then adjust the air jets then re sync the air then resync till any change makes it worse then ride it to see what you got their more senitive with the idle set low and it keeps to have a strong fan on the motor as sitting still with the motor out of tune till you get it right makes a lot of heat. When its right the sync gauges are on the same numbers and you hit the gas just some they all move together to the same number and hold RPM's just fine staying on the same numbers as if it won't do it the exhaust valves may be too tightand as it heats up everything changes and if you ride it it ca smooth out as the temp comes down with speed and the lash will open a little. Too tight and it changes too much to keep the tune.
