Weld-I think the engine may be 212cc. And it's 5.5hp, not 6. Because of the 0.4hp output of the stock engine, I might need to beef up the frame just a bit. I did find an owners manual online and according to the lawyer pages, you probably shouldn't even ride it.
Advertised top end was a blistering 14mph. Either of the Solexes would kill it in a drag race.
I have found a boatload of mini bike parts online, so stuff is available.
