2004 yfz 450 (ATV)

Question edited for full 'year make model (what it is).
Question moved from motorcycles to make model category.
Please don't type in all CAPS, it is considered SHOUTING and is harder to read.

'clips' and 'turns' it took me a while to realise you were talking about the carburetor and you were playing with the mixture screw and needle position! 4 turns out is a lot different to the factory setting which is 1 1/2 turns out.

If it is overheating it is running too lean. As you changed the stator, also consider the ignition timing. Popping can also be caused by the ignition failing under load, coil, lead and spark plug.

There is a good possibility that your main fuse is blown. The main fuse is located on the solenoid. There also should be a spare fuse that is stored on the solenoid, however, if it's blown, something has shorted to cause this, and needs to be found. An important note, if the battery has been hooked up with the polarity reversed, that will blow the main fuse.

There's also a possibility of a bad connection at that fuse, or in the plug that connects the solenoid to the harness. If this is the case, it would just need a little cleaning, or replacement of the whole solenoid.

try cleaning the carb.

that is a shift cam problem most likely. Pull the clutch cover and inspect the clutch shift quadrant and the clutch discs while you are at it.

I had a similar problem. pull start worked no problem, and starter only sometimes. turns out the starting system as a whole (starter, old wires, solenoid etc) were drawing so much power that it wasn't allowing much for power for the coil and spark. it was too weak

check the main fuse
