High Idle on a 2007 Night train

Got a new 2007 Night Train and it works fine BUT it has rpm like a japs. Is there a way to adjust the idle to really low ? I know that the high Idle is a sort of adjustment to create more power to the battery. but hey, I'm standing still as little as possible so the battery will be charge anyway. Or changing to a carb, would that work ?

The engine needs 950-1050 rpm's to properly charge the battery and supply enough oil pressure. Lowering it can effect both and is not advisable to do. There;s a small window to play with but it is better left at factory specs. As far as FI injection to carb, it can be done but at a cost and the same applies to idle speed there, just a bit more of a window because of no fuel pump drawing from the system.

I changed my dead battery on 05 night train....starts fine and seems to run good for about 15 minutes....then wants to die with very low idle at a stop..or slowing down


Hi Redmiston64, on the right hand side of the carburator there is an idle adjusting screw with a spring behind it, turn screw clockwise to increase idle counter clockwise to decrease idle. There is also an air/fuel mixture screw inside a carb body lug that may or may not be plugged with an aluminum cap that's about 3/16" thick. This cap can be drilled out to acess the air/fuel mixture screw. Turning screw clockwise will lean out mixture and lower idle, turning screw counter clockwise will richen mixture and raise idle. You need to balance the two adjusting screws to obtain an idle of 950-1000 RPM then back out air/fuel mixture screw 1/4 turn, snap throttle to confirm responce, you may continue to back out air/fuel mixture screw untill desired throttle responce is achieved, if you see black smoke coming out of exhaust you have gone to far and need to turn screw back in 1/8 turn at a time. Good luck.

What is idle RPM of Pulsar 150 DTSi 2007 model. Mine shows 1500 and after warm-up show 2000


Most bikes are in the 1000rpm range unles they are 2 stroke (some small Aprillas etc.), dont always go by the tacho meter, you can usually hear if the bike is idling too high or too low and idle adjustment is usually fairly easy once you find the adjuster screw.

Will not idle down


You have to take it into the dealer and have them adjust your idle with the digital tech, thats the only way to set the idle on these newer injected bikes.

Engine noise at idle speed


Sounds like it's time to adjust the valves. The noise you are likely hearing is due to valve train noise. I suspect you have loose valves. Also I would recommend making sure the carburetors are synchronized. If one side is off you will actually feel a roughness in the motor especially at idle.
When you remove the valve covers be sure to look for any dryness in the valve train. You want to make sure you're not having an oiling problem.
You'd be well off to just do a major tune up. Be sure to replace the spark plugs too.
