When is using a PA50 II motor NOT indicated?

(first post, be gentle)

I bought my first Honda PA 50. Sadly, it is a red 20mph bike, not a yellow 30mph bike.

This non-running moped came complete with an additional soft-seized motor. My brother got it un-seized, and I just got to looking at it and happily, the motor is a PA 50 II motor!

It is in pretty rough shape. The flywheel is all rusted and there seems to be no compression. And no carburetor. This motor looks like it would need some serious TLC to put right.

However, there is a 30mph variator and exhaust attached. I'm told that the best way to make a PA 50 I go faster is to put in a PA 50 II motor. I've got one, but I think that assumes a running PA 50 II motor.

What's the simplest way to proceed? I want to ride this bike before snow flies!

Use the PA50II's outer variator ramp plate, intake and reeds for a start. It'll give you a boost with your stock carb. Plus, it's pretty easy to swap over. You may have to file off the flat spot on the variator plate, to make the center round so it will fit on you shaft, and I think there is a pin on the engine case, but I don't remember off the top of my head. Basically if something gets in your way- make it fit.

Or I could trade you my pa50I's variator and ramp plate and a little cash for the engine!

i'm not exactly sure how that red/yellow thing works, but i've seen two red bikes now in wisconsin that are PA50 II's

yeah, the yellow red thing only works pre-1980. After that, its red/black and whatever, they stopped making the gimpy hobbits after 79.
