Are you getting rid of the stock airbox?
(on SV, to get rid of the airbox you can simply retain the stock catch can)
Try search on oldskoolsuzuki, catch can is a much more common mod on the older stuff.
By chrome hosing I presume you mean braided.
P.s such stuff ain't cheap! (http://cgi.ebay.com.my/Goodridge-Crankcase-Breather-Kit-Suzuki-GSXR1100_W0QQcmdZViewItemQQitemZ110317332834) You may be better going to a hydraulics company and seeing what they can make for you.
You will need a can with 2 ports, and if the port is not on the bottom (like on stock can) you will need to empty it occasionally and top up the oil more.

Don't have one fitted but they are supposed to increase torque or something arn't they??? (breathers)
My friend had one on a Bandit 600 but mentioned it didn't make any difference.
I think the silver pipes your on about are braded lines (like brake lines) but they only come with screw on fittings I think so you will struggle to do that.
Just a little info for you while you wait for a better answer. Personaly what ever it claims to improve it won't do it by much so save your cash :P

Nah that's boswallox. On a bandit they make sense as when you put K+Ns on the vents have nowhere to go.
A lower crankcase pressure helps to make a bit more power, some of the heavyweight drag bikes actually evacuate the crankcase with a pump, but it's a couple of bhp on a500bhp engine... makes sod all difference on a road bike!
You will be able to fit some braided lines to the SV's breather ports, but they are a PITA to get to. The rear one is in an interesting place!

There we go! Didn't think it would be worth it on a road bike.
but they are a PITA to get to??? What! (answered my own question there)

They only make sense if you have had to get rid of the stock system of dealing with crankcase gases.
Nicky S what do you want to know about how they work...

i would like to now how they work i kow they fillter small bis of metal out of your oil by the magnetic screw at the bottom. also i dont know if any one has put one on a sv or if it possible. also how hard are they to fit.
and for any one that asks why waist your money i like the idea of clean oil plus it is a lot easyer to empty and clean.

Nicky, you're getting things a bit mixed up here.
The lubrication system is kept clean by the oil filter screwed onto the front of the engine, it has a filter medium ("paper" if you like) which the oil is pumped through. This medium has pores which get smaller through the thickness of the "paper" so trap any particles bigger than the holes (which are pretty fine). The particles may be wear metals, but also soot type deposits formed in the combustion.
What you have shown is a catch tank fitted in the breather system, which deals with the gas which escapes past the pistons/rings and is a perfectly normal part of an engine operating process. This "blowby" gas has to be vented out of the engine to avoid pressure building up, and by law/regulation it has to be taken back into the intake of the engine so it doesn't pollute the atmosphere. Unfortunately it also carries with it some oil mist from the inside of the engine, resulting from the internals revolving pretty fast throwing oil around.
The oil carry-over in the blowby gas needs to be separated out as best can be achieved, and engines all have some sort of separator arrangement. Some oil inevitably gets through, and gets taken into the intake and is burnt, though this is undesirable due to deposit build-up from the ash, ansd possible contamination of exhaust catalysts and oxygen sensors etc.
If people modify their engines, particularly changing air cleaners, they might remove part of the separator system and what you show is an after-market kit which is intended to a) separate the oil mist, b) look chavvy.
Unless you have a good reason to change your breather system, leave well alone and spend your cash on something more useful. ;)
P.S. the filter thing on the top of the tank shown is there because many breather systems draw fresh air through part of the system (sometimes called "positive crankcase ventilation") which ends up in the intake, so needs to be filtered.

As well as deliberate ventilation there will be some manner of mixing too as well as simple stuff like dead bugs/sand/children falling down the pipe.

i see. so in other words i dont need one and it hard work to get something i all ready have just for looks ?? i know the oil fillter dose the job, but some of my m8s have them on there cars and i have a m8 with a bandit 600 with one on .. they all have oil fillters
thanks for telling me how it works btw :)
