Motorcycle Repair: yamaha flywheel puller, fastenal, shively

Question
I am not sure what it is called but i am trying to remove the alternator or stator. I can not find a remover/puller to get the flywheel off in my repair manual it shows the tool and it looks like a bolt with a square head. My manual says it's part number is YM-01080-A or 90890-01080. Can you please tell me what size bolt and thread count it is so maybe I could go to my local fastenal storeand get one? Thanks for taking time to help out  

Answer
Hi Chris,

Instead, why not provide me the year, make, and model of your Yamaha? Maybe I can find the part number of the tool or a link to the tool.

Include your email address as requested and explained in my instructions.
