Hi everyone new to the forum. I'm currently building a streetfighter out of my 1997 vfr 750

Where have people relocated to oil cooler to? Any guides, advice or pics would all be greatly received.

Thanks in advance

Hi, I was thinking the same thing for my track bike, as I have a larger one from an RC51 to fit.

Was thinking of fitting it below the std radiator using goodridge style hoses, mated to the original block mounted flanges, but this location is very closer to the exhaust and may not be ideal for a road bike. However on a track bike this might be a positive move, allowing faster warm up from the radiated exhaust heat. 

If money was no object I'd have a bespoke 2 piece HRC style rad with an oil cooler integrated into the lower rad. 

Another possible option for a streetfighter might be to mount a larger aftermarket cooler towards the rear of the bike, perhaps up under the rear subframe area ? A good excuse for some sexy plumbing !

Can the Goodrich hoses be mated relatively easy to the standard flanges and block?

Good ideas but I how hoping to do something slightly simpler. As I am new to the mechanical game

On a budget have to either cut and flare the original steel cooler lines to take a rubber hose, or weld an appropriate steel fitting to the pipe flange to accept a goodridge fitting. 

Alternativly get a machine shop to make up some nice aluminium fittings based on the OEM pipe flanges to bolt up directly to the ports on the block. 

There where aftermarket fittings of this kind available for GSX-R etc, but i'm pretty sure RC36 are slightly different dimensions.

Often used where motorcycle engines are used in kit car installations, so maybe CBR1100x would do but I've not seen them myself.

Thanks for the advice 

After some research the hoses seem fairly easy to sort out with hardline AN adapters and a weld on fitting it the cooler end.

Now just the issue of placement haha

IIRC, you can drill and tap the oil cooler to accept different fittings (adapters, I mean).  I think maybe Mohawk has done this?

IASTR that NC30 guru Rick Oliver developed some sort of oil cooler alternative using BSP fittings (my gripe with that being that BSP was not very common outside of Blighty).

But of course (no acronym, sorry), if you have a friendly machinist who can mill you a set of fittings, you're golden.  Although I'm not sure, I would expect all of the Hondas to use the same fittings; Goodridge used to list some for the XX in their big catalogue, but I don't think they are actually available anywhere. 

Ciao,

AFAIK, BSP fittings are commonly used on the Old Continent as gas fittings. 

They may go by another name (G ?) but they're BSP. Dunno about the US and not sure if hydraulic hoses use them, though. 

Edit: : Ah, the US have the NPT standard for pipe thread which uses a different thread profile. Not compatible.
