all bros,
b4 this my mechanic use 2 tulang ikan (4 valve each x 2= 8 valve) to boost 1 bar. But he only open 3 valve. so can i just use 1 tulang ikan and open 3 valve instead 2 valve on 1 tulang ikan and 1 valve on...
juz wanna know, is it really that we can change the hks sqv whistle(whistling sounds)? coz i have seen a few sqv with a different type of whistle colour such as yellow, blue, red and purple.
