For years ive been putting off pulling the trigger on one of these and then MDK Hard parts devision tanked... so i knew i could get the oil filter cover from PWR for 100 bucks and machine my stock cover myself to make it work and order a small cooler and hoses and try and build my own, after pricing it out, i should of just bought the kit. So through my hours wasted on ebay i found this kit. Its basically the MDK oil filter adapters and cooler (minus the sticker on the cooler mount) assembly and the guy throws a power steering fluid hose and fittings kit in with it... 120.00 bucks and its at my door, not bad considering the kit from MDK retail put you back 400 bones. First thing... theres no chance that this will fit with the works connection radiator braces so thats a bummer. I also had to switch from my after market hoses ( custom fluid works hose 2.99 a foot!) and back to the stock black one. no big deal. it has a custom bent mounting bracket thats welded to the side of the cooler. that fits nicely around the curves and creases in the radiator. I initially had some alignment issues as it shares the same 2 holes as the plastic radiator fins, this was a combination of production line drilled holes and i can only assume after 3 years the radiators are not exactly straight and true. so with some mild tweaking with a pair of composite pliers (didn't wanna narc the aluminum up!) i got everything lines up. i mounted the cooler unit then the filter adapters and then went to pluming. Thinking ahead, i left the the mount bolts loose until i was happy with everything. I was a little disappointed that i was provided with 4 foot of power steering fluid hose and these ugly Phillips head hose clamps.... the inside line on the cooler, once mounted with the hose and clamp, rests on elbow coming out of the radiator, its dose tilt the cooler to the right a little but this will easily be fixed once my parts get here but well get to that... it mounted up easy as pie and all in less then an hour id say. I asked the guy on ebay how much extra oil will this hold... he told me to check the window:bonk: So i added some oil and then let it run for about 2 minutes, shut it off and added a little bit more. Got it to where she was happy and so was i. Im not sure how much i added but im going to change oil this week so ill measure whats in it then. My first ride with it was yesterday at my track. Its a mix of really tight slippery sandy supercross with some semi long straight aways. I was nervous... something goes wrong with this thing we could have a whole bag of problems.. did a few easy laps and let it cool off with not issues. Then went out and ran an all out 15 minute sprint and it was all good, ever so often i would notice a little hiss or hum coming from down under that i haven't heard from out of my motor.. its either me hearing oil whipping through the cooler or now that im thinking about it, a pin hole exhaust leak under the sub-frame mount. investigation to come... anyway, everything seemed peachy after finishing that moto and then me and my buddy did a little free riding on some hills near by for about 30 minutes and then we both did a 10 lap moto following that and everything seemed to check out. The bike didn't seem to preform any different with it on but it looks cool and that what matter right? I ordered nylon hose and different style clamps to clean it up a little and get everything moving free. My winter plan is to cut the existing mounting bracket off and mounting the cooler like the PC bike mount theres; they have the coolers mounted on the inside next the frame and are secured with a mounting plate welded to the bottom of the radiator, the cooler its mounted to that with nuts and bolts, this version allows the rad, braces to fit! ill try and find a picture.
2nd Hand lions version of the MDK oil Cooler kit off ebay for 120 bucks!
On a 2007 CRF 450
Adds X? amount of CC's to the engine oil
Easy install and maintenance.
The oil is coooooolllllerrrrr:banana:
minor alignment issues (proably my fault)
Something else for me to worry about failing.
Rad braces didn't fit with this mounting method
guess work now that MDK is MIA.
Overall: Im glad i did it and i enjoy it as a performance part just as much as a conversation piece and project. Seems like the guy had a few of them on ebay if some of you off road guys want to search for one. Ill try to update the improvements i make to it... Sorry for the book! Thanks guys
This is the mounting system in going for, in principle:
