This kind of post is teetering on the brink. First off, it was a polite suggestion. There's a specific folder for these bikes and it exists for a reason...to make it easier for those specifically looking for info on these bikes. My reply would have been the same if someone had posted a restoration question in the "for sale" folder.
If there's anything that smacks of impropriety, it's hawking PRC product as genuine Honda, no matter how subtly or even if unintentionally. This isn't a personal attack in any way. The number of sellers out there claiming "made by Honda of China" , "made from original tooling bought from Honda", "made under license from Honda in PRC" "manufactured for Honda in PRC", "built to Honda specs in China" etc is huge. There's only one reason why these sellers continually try to glom onto the Honda name & reputation. In the wake of this widely practiced misrepresentation, a powder keg situation has been created. If the new bikes were superior to the originals, then the vintage bikes would have zero market value. The reality of the situation is obvious to most people and, as I've pointed out many times now, both OEM and clone machines have their own advantages/disadvantages.
The "22% faster" question still hasn't been answered. 60mph has been quoted. This can be interpreted as meaning a sprocket change will increase top speed to 73mph or that a stocker is capable of 49mph. Considering that 22% is a hard figure, the replies seem evasive. Implicit is that there is some basis for the claim. Why not simply provide the figures? It's to your avail.
"...putting a 120cc monster motor on it, it will own..." Come on, now, let's keep it real. I'm sure it will run well. But, when it comes to motorsports, the only constant is that there will always be someone faster whether its cars, boats, planes or bikes. Once the bike is built, post the results. People will decide for themselves. Boastful remarks just come across badly.
It's also plain to see how easily this kind of one-upmanship can go horribly wrong in a nanosecond. Having already seen what can happen elsewhere, I'd hate to see that take place here. This is one of the few places that hasn't degenerated into a s*** fight. Let's keep things on a mature, friendly, track. If the place turns into another planetminis, I'm outta here
