What should the AC voltage be on a Yamaha RD?
If you do read resistance the Stator is bad. Also check the output of the stator. With the bike running check the AC voltage output of each white wire. You should have 30 to 40 VACS above 2000 RPM.

How do you replace a stator seal on a Yamaha tank?
Use an impact driver to get the stator screws out. Then take a drywall screw and hammer it gently into the old seal. Only poke it through a tiny tiny bit. Then screw it in only until it grabs. Then use a hammer to pry, and pop out the old seal. Side note – if you can get the seal out with a pick instead of a drywall screw, do it. Good luck though.
