Manifold, Exhaust Bushing Maintenance - Vittorazi Motors Moster 185 Plus Maintenance Manual

3.7.2 Manifold, exhaust bushing maintenance

Clean flange contact surface with the cylinder from any gasket or silicone residue and check that
it is flat.
Check the integrity of the exhaust manifold: there must be no cracks or damaged areas,
otherwise it must be replaced. For routine maintenance, follow the table.
Check that the exhaust joints are regular. Small defects on the surface (sticking marks, cracks,
steps) must not prevent a regular motion of the joint.
