Trying to resurect my Aprilia Moto 6.5 and have found the rubber between the carb - BST40 - and inlet manifold is dead, deceased, popped its clogs. What other thumpers used this carb and might have an interchangeale bit? alternatively any help or advice at all would be much appreciated.
Seem to have buggered up the plastic screw that the choke cable goes into as well, will need one of those too.
nice thumper when it's running
