I have read the web page (http://www.itslookingup.com/moped/pa50/rampplate/rampplate.htm) titled:
"Modding a Honda PA50-I Variator to a PA50-II"
I happen to have the 30mph ramp plate from the original II engine. The carb and reed valve are also from the II engine.
Question: The instructions are to
"Mill off the side of the PA50-I drive face threads to accept the 30 mph ramp plate."
Is this all I need to convert the variator to 30mph? When I bought the engine via eBay I wasn't informed that it had come from a PA-I.
I had been wondering why the beast ran so slowly in spite of the engine running well.
Until I installed a replacement motor I had never had the bike on the street, so I didn't know what performance to expect.
Any input will be appreciated.
