748 Crankcase Breather Hose Diameters???

  1. Can anyone tell me the I/D and O/D of the crankcase breather hoses'?

    Will be replacing these. Guess I can measure when taking apart, but replacing with PTFE Oil Hose (Braided) so good to know beforehand. Can't find any info anywhere.

    Thanks.
     
  2. Just measured the neck on my spare crankcase breather at 19mm.
