I just corresponded with LeoVince, asking them what cyilnder the LeoVince pipe was designed for.
The answer:
The camino/hobbit pipe was developed/designed around the stock cylinder for the camino. All R&D testing was done with the stock cylinder.
Just information for us all. I had thought that maybe this pipe was specifically designed for a Malossi, DR, or other cylilnder. Guess not.
Of course, it doesn't mean that the pipe won't work with other cylinders, but it does tell us it was designed tuned for the stock cylinder's port timing.
