Is there a problem with my RMZ fuel injection?
The bike wouldn’t run clean through the RPM ‘s though and I see yours runs fine after started. Had an ultrasonic cleaning done and the bikes fired and ran fine after.The flow bench test showed increased flow after cleaning, but % increased with higher flow readings.
Why does my 11 RMZ 450 not start?
My 11 Rmz 450 is doing exactly the same thing, simply will not start no matter how many times I kick it, but as soon as I spray aerostart or something like that straight into the throttle body it will start second kick.
How does fuel injection work on a CRF450?
My buddy had the same problem with his CRF450. Turned out to be a bad ECM. There is a circuit in the ECM that supplies the voltage to the capacitor to fire the injection for starting. Once the bike is running the injection gets it’s voltage direct from the stator, or something like that.
How can I Fix my fuel pump problem?
I have replaced the fuel pump and the stator, valve clearances are all in spec, timing is spot on, new piston and rings, all this done after the problem started and still does exactly the same thing. Fuel injector works perfect on the bench with a 9 volt battery but once it’s in the bike it won’t spray while being kicked over, so no fuel no start.

How is the drive ratio of a Yamaha YZ250F determined?
To determine the final drive ratio, divide the rear sprocket size, say 49 teeth, by the front or countershaft sprocket size, say 13 teeth (like a new Yamaha YZ250F). In this case, the Final Drive Ratio is 3.77 – the front sprocket revolves 3.77 times to make one complete revolution of the rear sprocket.
When did the Suzuki RM250 lose its power?
In 1983, the RM250 loses power and the other Japanese companies catch up. Over the next few years, the Suzuki doesn’t quite keep up with the rapid pace of technological improvement in the motocross world.
Why is my fuel injector not working on my bike?
Fuel injector works perfect on the bench with a 9 volt battery but once it’s in the bike it won’t spray while being kicked over, so no fuel no start. Why would no power be getting to the injector on initial start up. When the bike is started with aerostart bike runs perfect, doesn’t miss a beat. Frustrating.
How is the speed of the injector controlled?
The injector in a basic picture is an electronically controlled valve that is supplied with pressurized fuel from the fuel pump at a certain pressure level injector can be electromagnetically opened and closed at very high speed—this speed controlled by the electronic control unit using.
How can I test the resistance of my injector?
Another way to test the injector is to measure the resistance of every injector between the two terminals and compare it with the highest and lowest values stated in the injector datasheet; if the result outside the allowable boundaries, then change this injector.

What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
Why does my bike start with a bad ECM?
Turned out to be a bad ECM. There is a circuit in the ECM that supplies the voltage to the capacitor to fire the injection for starting. Once the bike is running the injection gets it’s voltage direct from the stator, or something like that. Bottom line it was a bad ECM. Powerband in every gear ! Double and triple check your timing.
