Inliners International Forums General Discussion Hi Performance Idea on the "lump port" design

John C- I've tried the tounge or thin sheet metal lump. It didnt work! Because The air passing thought the port would lift the sheet metal peice just a little. After a period of time the sheet metal tore at the base of the lump and got sucked in the motor. NOT A GOOD SOUND! Stay with the bolt in lumps they are worth years of trouble free service.
