Correct p# is 07937-4300000 as shown on puller I bought from Honda some time around '82. I'll see if I can determine the thread size and get back to you.

The lg center bolt on the puller that screws into the center of the flywheel has a metric thread size of 18 (probably a 2.50 pitch). See attached pic.

The tool in the pic I posted pulled the flywheel off my '74 MT125 a couple years ago. I wonder if Honda changed thread sizes during production. Strange.

Just a guess, but the MT125 flywheel threads look the same as on the MR175 flywheel. This flywheel takes an M27x1.0 LH-thread male internal-thread puller, such as the K&N 82-0150, Motion Pro 08-0026, etc.
