Nice video John, great to see an install video on the Morin oil cooler for the Monkey and with the way it’s suppose to work with that head stud I think I’ll give this mod a miss for my bike
Thanks! With the one half sheet of instructions coming in Chinese or a language not familiar to me, I think this will help people. Probably pretty easy on the Grom, but a little different for the Monkey. I too don’t think the cooler is too effective using the head stud method of oil delivery either, and will probably go the way of a side cover with oil ports route in the future
Thanks for another informative video! This is a job I will be doing tomorrow on my Monkey Bike! fitting the MSX 125 Morin oil cooler! I have already fitted the Kitaco Clutch cover so my oil lines will go direct from the oil cooler to the clutch cover! So I think I will not need that cover that goes on top of your engine head! the one with the oil port? I think I will not have the issues with clearance as the bracket should bolt directly the same as yours on the two top head bolts! I think I will not have the problem with clearance from the front mudguard as I have already fitted a Kitaco front mudguard lowering kit? The Morin kit certainly looks a lot nicer with the oil lines than the Kitaco oil lines and cooler! I will post my findings and let you know how I get on! Thanks for the great videos and keep them coming!
Awesome job on the video (as usual). That's an interesting install, it's have already pointed out what seems like questionable decisions on TB Parts side of things. Not many options on a stock head, though, the kitaco side cover has made life a little simpler on my install, but cool to see some innovation at least.
Thank you!! At first I thought TB made this cooler, but now see that Morin makes it and TB probably just imports them. I believe the Kitaco side cover is the way to go as well and I’ll eventually end up with that to help make life a bit easier on oil changes and to help this cooler work a bit better
@stelio yeah I’m not sure what’s going on with that. I know TB is a distributor for a lot of items as well and think this is the case with these shocks. Where they might not have them on their site, but sell them to other shops for retailing. I know MNNTHBX has them on their site as well as TBolt.
Honda Grom here. Stud torque is 8 ft-lbs. I had no trouble using a pair of 8x1.25 bolts as jam nuts to remove the original stud and torque the new one down. Stock instructions are pretty bad.
I'm very impressed with your modification skills! 1) how much would charge to make me t same bracket bc I love t placement of t cooler and I cant/wont do that kind of work 2) I wonder if my chimera intake dimensions wld conflict with your new bracket design, hmmm 3) do u have the super flow oil pump on your bike 4) are u worried abt stealing critical oil flow from the engine and thus increasing engine temp/wear? My 181 bbk blew up due to heat n sustained highway speed. I'm having it fixed and adding a digital engine head temp read out. Then I will run around monitoring engine temp under different conditions b4 I decide to do t cooler. Since I know how 181 bbk feels b4 death I shld be able to get some good Intel without doing serious damage to t engine. Thx!
Thanks! I’ve done this kind of “reshaping” so many times with my racecars, so I was confident I could make it work. 1. I am thinking of designing a bracket like this and selling them, so yes. How much, I don’t know yet cause it all depends on how much it costs to manufacture them. I have good manufacturing connections though from our Miata business. Stay tuned on that. 2. That’s a good question and I am not sure! It might hit other intake designs and I really custom designed it to work with my bike, which has the Mtake. 3. I don’t have any mods done to the oiling system. 4. To be honest, I’m not sure if I understand how this cooler gets any oil at all! The channeled stud doesn’t seem like it would flow too much oil to me, and if I am gonna get serious with an oil cooler, I’m gonna go with the side cover that has the oil ports on it near the oil pump, with an upgraded pump
I had to look this up, and see it on eBay. That looks more complex actually, and still uses the channeled head stud. It is however a good solution for using with the stock air box. Thanks for pointing this out 🙏
Ive read a discussion about that oil cooler installed in the air cooled engine is bad?.. because it slowerd down the oil pressure from the oil pump going to the designated area such as crank shaft ,connecting rod spitting to the piston. The oil coming from the crank shaft spitting to the piston cant get enough oil to spit because the oil cooler is sucking up oil pressure..
its not true... there are 2 holes in the head. 1 is going to Pisto and the is in the Cams to timing chain... Its normal because the Engine is Soaked in Oil stator design.
I have just watched this. Am I correct but one of those hoses does not actually pass oil through it and is just fixed on a cylinder head bolt? If that is the case; surely there is no circulation through the radiator as the oil is only coming in to the radiator and not returning back to the engine?
It’s a channeled head stud that’s designed to allow oil to travel along it. The oil flow in these engines push oil through that stud to the head, so this is why this cooler is designed this way. How much oil it moves is debatable
Are you using a high volume oil pump with this kit?, it's really not doing to much cooling, that setup would only cool the rockers and cam, at most, the Kitaco and Takegawa setups cools the big end and the underside of piston plus the rocker cam assembly's
No, stock pump. I agree it’s not as useful in this configuration either. I shot this video to help TB Parts see if the cooler worked on the Monkey installation-wise. For the best efficiency, a side cover with ports would be the better option for ultimate oil cooling.
I am trying to put on on my monkey and this video is very helpful. One question though; do you need to put in more oil or even have to prefill the oil cooler?
Hey John, was just looking at this video and seen you had to modify your bracket for the Monkey install.I almost think it wasn't even designed for the Grom. I put one of these kits on my wifes 2020 Honda Grom with a TB Big bore kit. I mounted it the way directions show coming off of the 2 bottom head bolts. Needless to say we are on our second bracket. the tabs on the bracket keep breaking off where it mounts to the head. I have a2015 Grom where the cooler mounts to the tappet and haven't had any issues. It seems to me that the cooler might not be cut and dried install for either the Grom or the Monkey. It also seems that the pieces that are part of the oil cooler assembly tend to rattle from vibration. Im just curious if anyone else has had some of the same issues. makes me think there should be some kind of redesign for the bracket or a relocation to the tappet cover. as always great video thanks for the time you spend to inform us.
Yeah I don’t think the cooler is designed as good as it could’ve been. I couldn’t have it mounted so low because of my off road riding, so I had to modify the bracket to put it on top. It didn’t really seem like it was doing anything anyways, and I feel the feed method of the channel bolt is ineffective
The more of these “mods” I see done on these the more convinced I become that you are way better off to leave it stock. I definitely wouldn’t buy one that someone did any type of mod on it. Save your money and spend on maintenance. Your bike will run better and last longer not to mention mods devalue it substantially. Keep it factory parts when doing maintenance or repairs.
Mods don’t do much to this bike in terms of performance, it’s more for the fun of tinkering than anything else. A pure stock vehicle (any vehicle) is 99.9% of the time perfect from the factory with that OEM’s spending millions on research, testing, and development
Do you think the pump has enough strength to push the oil round that oil cooler especially as you are mounting the radiator so high up. Do you think it would really help with cooling? I ask because the Honda Monkey/Grom is manufactured in Thailand for the world market. They are popular in Thailand, especially the Grom and I have not heard anyone complain about overheating etc.
Did you ever get any benefits from this oil cooler? I have one on my monkey, and I don’t think it’s doing much. It’s definitely not cooling it down as I have temperature sensors to verify this.
hi ! I am a honda monkey 2020 owner and I just saw your handlebar video, can I fit the handlebar on my 2020 and where did you bought it from ? thanks 😄
Yes you need to Run the bike for 30 seconds and add oil needed to bring it back to prior full and repeat as necessary unti your dip stick (or sight gauge 2022 and up) shows full
Does this also come with the intake ? I’ve been wanting a intake on my monkey and there all pricy, I feel like for $170 you get an oil cooler and intake ? Seems too good to be true or am i buggin
Paps! Can you give more ideas tutorial about honda 150 supremo 3gen.which part of this motorcycle can installed oil cooling system im newbei in rhis field can you help me about this.
I wish I could, but sadly haven’t heard of the Supremo before 😕 Also, I would have to have an example of one in the shop to be familiar with how to modify it
Is your mc's engine is the same engine with the xrm 125 fi here in the philippnes?? I would like to install a cooler just like what you had installed. Thank you
I didn’t measure, and just topped it off on the window. I didn’t notice much more needed when I did an oil change last month, but it could have already been in the cooler
John, Changing my monkey front sprocket and cant get the rertainer that hold the sprocket to engine to line up with the sprocket,,, Can figure why it will not help me out man
I added a little extra oil, but I don't feel the cooler even flowed much oil, it's kind of a novelty part and the right way to add a cooler is by way of plumbing it to the oil pump, which requires the Takagawa replacement side cover with the oil ports.
You defiantly need the Hi-Flo Takagawa or Kitaco oil cooler when installing this kit! as your adding volume to the oil system you need the bigger stronger pump!
No worries at all brother! Ain’t gonna lie though, you kinda scared me for a minute because I filmed this last fall and just had a good chance to test the cooler as the bike was cutting out for a long time. I was thinking something was messed up with the recording 😬
I wasn't impressed with it and have since removed it because I installed the high-compression piston. The next step would be to install the Kitaco side cover with the oil fitting direct to the pump area to supply more oil to the cooler. Not sure I need that at this moment though
Absolute JUNK.. I watched this, then ordered one for my sons Grom, installation was easy, however, the new headstud (with a channel cut for oil) is supposed to seal against the bracket. I tried three different washer setups and it still leaked. The actual cooler was ok, however, you really have to watch the lines from the tappet cover to the cooler, as flat as possible with no loops. Had a pretty good loop at first and the bike temp rose, however the cooler was cool to the touch and it leaked at the return line at the head. Re routed the line to a flat position and got better oil flow, however, the return line would not seal at the head.
