Engine/Gearbox Breather Pipes.

Just got back from Afghan and I'm going over the bike to check things are all ready before the start of the season.

It has slipped my mind about the two catch bottles that are required for the Engine and Gearbox breather pipes. 500cc and 250cc respectively.

Am I right in thinking that these are the two pipes that in standard trim run down the left hand side of the bike and finish up next to the engine casing?

What bottles do you use? Coke bottles? And where do you mount them?

Also on a slightly related subject it mentions about a non return valve for the fuel tank breather pipe. Any ideas on where to get one?

Cheers guys.

I'll go take a look at where they happen to go on my bike and let you know.
