So I bought a Posh CDI after doing quite a bit of research and coming to the conclusion that this is the best CD for the Honda Ruckus. It was actually kind of hard to find as most people where out of it. I think I ended up getting it from CoreSport as they had the best deal, and they had it in stock.
I knew the Posh was a bit trickier to install than most, but it would be well worth it. The only problem with the Posh units is they come with Japanese, or no instructions at all. So I did some digging around and I nfound a few different resources for installing these things:
This helped me a lot and hopefully it clears up some of the fog when installing these things. I installed this while at the same time installing a Dayton Drag Variator.
With this particular variator, you MUST upgrade your CDI or you will bounce of the re-limiter all day. The combination bumped my max Mph from 37 to 42! Most importantly my torque and acceleration significantly jumped which is exactly what I wanted because I live in the city and I battle hills all day, plus IO weigh 210 lbs.
I highly recommend this Unit
