Thank for these replies, on the 240.320 Rotax engines there is a short stub to connect the breather pipe so an easy fit, on the jumbo just a grommet with a hole unless i am missing a part, do i just thread a pipe in and seal it best can looking at pics of other jumbos they seem to route it behind the engine/ swing arm pivot alongside the gearbox breather pipe with a zip tie
Many Thanks
Geoff
