There are tons of tools out there, and they all seem to have different bolt sizes and thread pitches, etc. I would like to order one that has multiple sizes with it, but I have no idea what size my son's bike requires.

Can anyone tell me, or link me to the correct tool? It doesn't say the size in the repair manual. I have tried searching, but unable to find the needed info.

Thanks in advance!

 

I looked at a fiche, it looks like there are 3 threaded holes in the flywheel. Correct?
If so, you'll need a 3 prong puller that you put bolts thru to pull on.
It's a good bet that the holes are 6mm x 1.00 threads.
