[QUOTE="F-Bomb Pilot115, post: 62286, member: 22818"] If you read your manual it tells you NOT to twist throttle because the carb has a pump on it that will fill the cylinder with fuel causing huge backfire that will burn bike up with screen or no screen. The screen is built in ti the filter cage & Yamaha swears you lose no horsepower with it on. All 4 strokes have these cages due to backfire, that is why you are not familier with it on 2 stroker ------------------ [This message has been edited by F-Bomb Pilot115 (edited 04-19-2001).] [/QUOTE]
