i have just purchased a giannelli exhaust for my lc '07 speedfight iron-x but the standard exhaust has an additional pipe which connects to a hose going to the engine. i tried fitting the giannelli exhaust with this hose just loose and my scooter would not move
try plugging the tube with something i think it something to do with the restrictingof the bike. it recurculates the exhaust fumes or somthing. maby wrong but worth a try
