1200 Sport Engine Breather

Technical All CARC models

Has anyone had any experience of blocked or restricted engine breather or any breather mods? The timing position sensor weeps oil despite renewing the o ring and there is a very slight weep from the main bearing seal. Cylinder compressions are good, but I wonder if the crankcase is getting pressurised a bit.

Constructive suggestions welcome.

most of the breather pipes go into the plastic box that sits in front of the air filter case, so I would start to look there first and work back from there, one of the pipes does get trapped to an extent so that it is flattened a bit if you are not careful.

out of interest what pressure readings are you getting?
