Ok, my fault. I get that, it only depends if the finger is on the hose in the engine. If it can get air in some way, it will drain. Not much experience with these engine's, sorry. I will shut up now and hide under a rock again.

I will shut up now and hide under a rock again. Both end's of the pipework to the cooler is technically submerged below oil level all the time, so in this case, the oil is both the "finger" and the "water in the glass" so no air can get in, unless you drain the system. (Interesting side-thought, After an oil change the system does ofc drain itself, but do we worry about that when we hit the starter after an oil change? nope.)

When you hit the starter the engine will imediately fill the cooler, creating no pressure.

I get the feeling someone will say something about magic soon.. I'm now pretty convinced (after some quite Intellectual shouting that I'm going to do mine bottom entry (oooeerr missus) just for that reason. His much pressure us supplied by the oil pump? Will I have to remove the cooler to drop it below the level if the filler to ensure no air block? Cheers for help BTW guys

Cool makes oil changes considerably easier!
I k ow pipe diameter of hoses to and from cooler will make a difference to the pressure, what sort of hoses would be better, larger diameter for less pressure / higher flow or thin hoses for increased pressure. The original b12 hoses have a mixture of both! Small diameter at the ends and larger diameter at the flexible section!

Good question.. I think there's only one size hose that fits the blue red fittings as most people have used, and since it has been done, it works. If it makes a big difference I dont know ?

There's several hose sizes and matching fittings. AN8 being the most commonly used for fittings on bikes and AN10 in cars. AN6 is used for head coolers. Brakelines and banjos are AN3. Here's a chart with various sizes and data. www.earls.co.uk/earls/technical/Thread%20Sizes.pdfAN10 has been used on plenty of bikes because the coolers, hoses and fitting are cheaper than AN8 stuff.

Why do a lot of builds have the hoses at the top of the cooler? is it just so everyone can see the (fake) goodridge hoses? IMHO they would look better with shorter hoses. Is there any other reasons they go in at the top? clearance from header pipes? I fitted mine at the top for the reason you have suggested, clearance from the headers being my main reason

It's all in the angle of the dangle.

But can you use both the smallest size hose, or the biggest, on a an8 fitting? Thats what I meant, since he was asking about what size to use?

The AN sizes are not that hard to figure out. It's all to do with sixteenths of an inch. 3/16 = 3AN which is braided brake line. 6/18 = 3/8 which is used a lot in head coolers 8AN is 8/16 which is equal to 1/2 an inch so you use 1/2 inch braided hose to suit. You don't use any other size fitting with this hose. There's a host of adapters out there so you can mate any size fitting to another, such as use 8AN hose with 8AN fitting and adapter to fit to a 10AN cooler.

Ok... thanks for everyone answering my daft questions.
as I'm using the thing daily I need to get all the bits before I start any job!
Last question....
Where the banjos currently fit on the engine, what fittings will fit? will I need adaptors from metric to an-8 etc..

Whilst you can shop around and possibly get things a bit cheaper there is always the risk of buying the wrong bits so i'd advise phoning somewhere like HEL - tell them what you've got and what you want and they'll sort you out. They may even be a site sponsor so mentioning OSS might get you a bit of discount! With regard sizes - cooler outlets are usually 1/2" BSP or 5/8" BSP - Personally I prefer the larger and use dash 10 for the hoses for main coolers and the smaller with dash 8 for head coolers or secondary coolers. GSXR oil pumps move something like 80 gallons a minute so no need to strangle them!
