doing dual cans, one for cam covers and one for crankcase, does anyone know where you can get hose the right diameter for the crankcase breather vent? I think its 21mm?

Got all mine from an aquatic shop. Sold in black, flexible and easy to cut. Not too cheap to break etc.
Mine has lasted 4 years under there and looks very OEM/discrete rather than miles of aftermarket water hose and jubilee clips.

I did all my breather mod for under a £10 mote. Ceapest mod I have ever done!

If you're taking one off the main crankcase vent and ditching the two way adapter thing on it, then yes, it is something like 20mm.

I use my local marine supplies shop -every kind of hose you want, stainless hose clips etc, very handy! Apart from the oversize crankcase vent, the rest of the system can be done in 13mm.
