Oil cooler removal
I've removed my oil cooler like most of you have, my question is do I blank the 2 oil holes up with blanking plates or make it so it still flows round in a full circuit? If I make it a full circuit it's ran at high pressure so what's best way to make a good pipe system? Thanks

Re: Oil cooler removal
There are two schools of thought on this; one is that you can simply blank the holes and rely on the bypass system for the oil to flow and the other is that you should make a pipe to flow the oil through as it was intended. Personally, I always went for the latter as I thought the bypass was leaving too much to chance, but I know others that simply blank them off and I'm not aware they've had any problems.
If you do go for a pipe, I got mine made up for me by Earl's Performance for around £40-50 from memory. I sent them a picture of the underside of the engine/sump and explained what I needed, plus sent them one of the old pipes to the oil cooler so they could see what fitting I needed. They sent me the right fixings and length of hose plus oil seals and I bolted it straight on....easy I used it for three seasons and swapped it from one engine to the next several times with no problems.

Thank you for the reply, I think I"ll get a pipe made up to be on safe side

Re: Oil cooler removal
Another school of thought is to stick a zx4 sump on there.

Re: Oil cooler removal
You'd need to swap oil pick ups on that mod! zx4 sump and zxr400 sump have different depths and different oil pick up lengths so careful over time that =BANG!zxr500man wrote:Another school of thought is to stick a zx4 sump on there.

Re: Oil cooler removal
Nice one- you mean the oil pick up? I actually bought a zx4 sump on ebay the day after i posted the reply to you, just to see what the difference was in depth of the 2 sumps and cud anything be done, so whats the story, much of a difference?

Re: Oil cooler removal
IM starting racing this year on a zxr4 , all the mods are a bit new to me, whats the advantage of removing the oil cooler? And is it an issue if its left on, as mine still has it fitted.

Re: Oil cooler removal
No probs with leaving it on. Ive got one race bike with it on, one without.They only real saving is the weight and not having it can make fitting the fairing a little easier if you have to lower your water rad for an airbox scoop.

Re: Oil cooler removal
I'd probably stick it back on for the road. I'm sure you'd be fine for 99% of the time but that one one hot sunny day stuck in traffic for a while might see the oil temp get really very high. Just my opinion but its all just guess work.

Re: Oil cooler removal
Hi
Could someone post a picture of one of these pipes please, just so I've got an idea as to what one looks like please before I try and explain to the guys I use to make my hydraulic lines?
Cheers

Re: Oil cooler removal
I haven't got a picture but I've basically done away with the oil cooler and used the metal piping that flows return and feed oil to the cooler and welded them together to make a solid loop pipe. I've done one track day and one 1.5 hours on dyno with no problems since
