When you guys cut the seat foam, how exactly do you do that? Do you cut from the top or bottom? Do you cut a slice off the whole thing, or just out of the middle? And after you're done, how do you get the seat cover to go back on right? (For instance, wouldn't the word Honda be wrapping around the bottom of seat and look pretty trashy?) Any advice you could give on this would be great. BTW, this is for my buddy, he's in the ballpark of 5'7", and can just touch the ground on tip-toes. Thanks!
