Before you start let's be clear. You are getting a measurement of 1.2 ohms on your meter from one white wire to another white wire? If so, that's fine and they're in good shape.
If you're only getting 1.2 volts ACV on your white wires to ground with the engine running, then they are damaged and you need to do what I list below...
from above posts I wasn't sure what your situation was.
First you remove the timing cover, which is on the left side, and says yamaha. 4 bolts.
I poked holes in a pizza box in the pattern the bolts were in on the side of the bike to keep track of where they go back to.
the clutch rod case comes off easily, just loosen the clutch cable at the adjuster nut on your handlebar before you take it off.
Once the clutch rod cover comes off, you'll see the chain sprocket, the yellow wire, the blue wire, and the wiring going into the stator and coil. If you see breaks at this point you're happy, but it often takes pulling off the stator cover too and looking at why there's a shortage. I had to cut off the shell around the bundled wiring, sort of a long sleeve of black pvc, that had hardened and cut my wires up, admitting oil and causing shortages.
back to the stator cover. Inside the timing cover you'll see the bolts holding the field coil in place. For now leave them attached. remove the bolts going around the stator cover and put them in the pizza box holes in the pattern that matches them on the bike. This is because they're not all the same length.
Cover your pipes with aluminum foil beneath the stator case so oil stays off them. If it smokes later you'll think you fried the bike and smoke needs to come from only one place. Put an oil pan or oil catcher beneath the timing cover area. It will drop a pint of old oil with the stator cover removed.
You'll need to pry up an edge of the stator cover because it's usually gasket sealed to the other half. Don't stress about the gasket, it's just a heavy paper template. You can make one after the stator cover is off the bike.
The stator cover indexes onto the bike with these large circular key pegs that are hollow in the inside. I pressed them onto the heavy paper to get an impression, cut out a hole the same shape, and then pressed the paper down over the cut holes onto the key pegs and traced the outer edges of the stator case to get my outer dimensions of my stator gasket. The inner I matched by taking the old pieces of the old gasket and laying them into the new outline I cut for the new gasket. New shape minus old shape equals gasket. Then put the gasket aside for later.
Get in there and make sure the wires are all intact and not touching each other or any oil if they are dented or dinged. If they are they will not measure the right ohms (1.2 to each other on white wires, no ohms when measuring white wires to engine or ground.)
The stator is stubborn and will not come out easily if you get it crooked. So inside the stator cover, you are going to undo the three bolts that hold it down and put them aside, as a group. label them.
The stator should stick up above the ridge it's bolted to the same amount all around. Make a depth measuring tool from a long thin piece of wire or something. Same height around is good. One high side is bad.
