solution

new exhausts combined with new flange M 8 G ( flangia scarico inox exhaust flange) and M 8 G 1 (guarnizione scarico exhaust gasket)

can cause the exhaust studs to come out of the cylinder and some to break off.

enlarge the 2 holes of exaust flange to 7 mm or more,

than use Loctite 1372 sealer instead of M8 G1 gasket

the studs must be insert 12/15 mm inside the cylinder

with the exausts 02 serie also the bolts must be used ( 6 MA - thin) to fix the inox flange.
