Default Re: Top Speed, 80cc Chinese motor? what is the record?

My first pipe was an old pocketbike pipe and it did let the bike accelerate very nicely but top speed was in the high 20's the pipe's outlet was just a hair bigger than the stock pipe's, the KTM pipe's outlet is almost an inch wide... bigger than the original header pipe...
