Hey guys, I got the 88 vert and the stock seats are so ugly so I replaced it with one of the carbon fiber Netami racing seat. But, I can't seem to find out how to adjust the lower back of the seat and it's killin my back because it bulges out, like most seats that u can adjust that part it'll go in and out but I can't seem to figure out how or if u even can? Anyone ever used these seats or kno of a way to fix it?

Thanks!
