In Malaysia, we have a method to clear up the carbon deposits that clogged the exhaust pipe of 2-stroke bikes. The exhausts in the picture is the one for Yamaha 125Z. This method works but need to be done properly. So far, the exhaust works better after the burning and none of the parts inside the exhaust fall out. The sound is noticebly crispier and more ‘ting… ting..’.
