factory oil cooler

ok i have a 202 r1 and really wanna add an oil cooler or at least run a line to the clutch cover to cool the clutch plates as i pretty much only drag my bike. i jus bought a service manual for the bike and saw that it has a factory oil cooler mounted behind the headers. my question is could you put some sort of a t on either the intake or discharge line of the cooler and run it to my clutch cover or through another cooler and back to the clutch cover. similar to the mccoy bikes. i know on the 04 and up models there is a plug you can just pull out to access an oil supply, but no such luck on the older models. i guess real question is how and where does oil flow through the factory cooler, and if you t'd into it would it affect flow or pressure through the engine. any help is very very appreciated. i am not a total idiot about bikes/engines, but i admit to bein out of my comfort zone on this. so thanks in advance

not sure on flow either, but i would suspect as long as you tap into the return side that you wouldnt loose any pressure and T it into oil line to clutch cover. not sure which way it flows on bike, but i would just check it before and after and make sure you dont have pressure drop. also even with my oil line kit, i run oil little high just to be on safe side.

i cant really tell what its internals look like in the manual. all i know is it has an inlet and outlet for coolnt to i guess flow around oil in this cup thing. looks like an oil filter with 2 pipes comin out it. guess i could take it off and try to see how things flow inside and try to see if i could drill and tap it somewhere. its gonna be a biatch to get to cuz i gotta drop the headers and all. so i wish i could get a solid answer before i go tearing into it. like i said i not to comfortable wit this project. i really gotta do research before i do anything. my girl says im anal i say im just thorough ha ha

lol i know feeling bro. i dont like tearing into anything without some sort of plan. wish i knew more to help you. you gonna be in town for Fat Tuesday racing? not sure i will have mine together, but damn i want to make it to hattisburg.

that saturday is supposed to be an all bike day its gonna be insane, lot of heavy hitters comin down and lots of money will be changing hands. if my schedule stays the same i will be gone for it, but i supposed to be going to work on a new rig after so maybe that will throw off my schedule so i can be home for it. if nothin else i might have to jus fly in friday, race saturday, and go back out sunday, my boss should understand right ha ha ha

Whoa........before you try to tap into the oil cooler, you definitely need to rethink that. The oil cooler is the first place oil flows in the R1 engine after the oil pump, before it flows anywhere else in the engine. Tapping in here with a T will significantly drop oil pressure to the critical parts of the engine. I have a diagram of the oiling system, and I will make some pictures to send to explain this. But basically, if you are looking to reduce oil temperature, my first starting point would be the addition of an external oil cooler. You would want to add it into the oiling system in series, rather than with a "tee"; and the easiest way would be using a sandwich style oil filter adapter, which will go behind your oil filter and send oil to your cooler, then through the filter and engine. As far as clutch cooling goes....I have never seen the system you refer to with "lines running to the clutch cover". However, if the purpose is to spray cooled oil onto the clutch plates for additional cooling, you can tee into the oil line returning from the cooler to the engine. But you must keep in mind that this is your engine's main oil supply. To keep engine oil pressure from falling, you will require 2 additional considerations: 1) metering orifice - the line running to your clutch cooler must have an orifice installed to meter the amount of oil going to the clutch. A simple jet installed into the line, or precise sizing of the nozzles spraying onto the clutch, will control the volume of oil going to the clutch cooler (and thus the amount of oil left to go to the engine). 2)regulating valve - some sort of pressure regulating valve must be used to keep the clutch oiler from using oil when engine oil pressure is already low. A regular spring-loaded check valve can be used, set to flow to the clutch cooler only when opening pressure is attained. The opening pressure must of course be lower than the bypass pressure of your oil pump to make the system work at all. With that in mind, if I were to design an easy clutch cooler using readily available parts: I would use standard -3an stainless lines and nitrous system flare jets to plumb the clutch cooler and control flow. I would use a wilwood 10psi residual pressure valve to make sure the clutch oiler does not activate when oil pressure is under 10psi (at start-up, or in the event of an oiling system malfunction). Remember, in order to "hold pressure" in the main oiling system, the valve should be installed with "out" facing the oil cooler/filter, and "mc" facing the clutch cooler. As with any oil system modifications, I would recommend installing an oil pressure gauge to the engine's main oil galley and recording oil pressures before (idle pressure, max pressure, and rpm where max pressure is achieved) and after any modifications. I would expect to see idle pressure remain constant or drop slightly, maximum pressure remain the same (70-80psi), and max pressure rpm raise slightly.

the lines on the cooler are water lines.
