Grom Oil Pump Mod How To

This is a how to video on modifying the oil pump pickup on a Honda Grom. This mod works on all years and all pumps. This is a must if you wheelie for fairly long distances

[@EstebanAGaido]

Man... use a holder when drilling stuff... I have a thumb with a nasty hole in it for a drilling accident!! Be safe.

[@jannummensalo2193]

Very good and informative video. Regards from Finland!

[@attnckr]

im a fan for life you guy speak my language i love it!

[@TwistedGripGarage]

Awesome! Glad you like!

[@jbean530]

I like your ingenuity. If I send you some metal chain gloves, would you wear them? I might consider sending you a table clamp if you would use it for your drill work. Fingers are irreplaceable. Blessings.

[@TwistedGripGarage]

Thanks for the offer. I have metal gloves and a clamp. Just didn't use them on this video. Thanks again!

[@glutenfreegam3r177]

VERY nice work! I am surprised this video doesn't have more views and comments as this is such a great video. Did you ever try soldering the copper tube to the pump housing?

[@TwistedGripGarage]

No, I tried to keep it simple as possible for people to do it themselves. Not everyone can solder but anyone can squeeze a tube of rtv... lol

[@mikeoberle6413]

Copper and aluminum can't be soldered together. The best option would be a mandrel to form the copper to fit the oil passage and use an epoxy to seat and seal it.

[@FinnaBin]

3 years later and still the only pickup how to video i can find lol

[@sazzcharles6129]

so true, best video i've seen on this mod

[@XxPuffyWolfxX]

Lmao took forever to find someone who actually does the mod. Everyone else just shows only the after part

[@ShooterMcgavin6]

Why not use aluminum tubing and solder/braze or tig just a thought

[@TwistedGripGarage]

Mainly because this simple solution works great. It doesn't have to be over engineered. I think there are a few people that are soldering them in but for the average diy person, this is the best route.

[@bimmerbob8483]

Thanks for the video. How Long do i need to wait for the rtv to cure before riding? It says 24 hours on the tube. But how long did you let it cure?

[@TwistedGripGarage]

I waited the 24 hours.

[@thegraffitiwriterknowsas6821]

This is so sick

[@andrewlouderback]

That extendo drill bit tho! Haha

[@chrispy9913]

Yea man I was gonna say aha

[@paulhartman7144]

The oil pump didn’t have a tube before ! How did the oil get into the pump before the tube was added. where was the original pickup for the oil pump ? Can someone explain the routing

[@TwistedGripGarage]

An unmodified pump will pick oil up through ports built into the case. Where the pick up port hits the oil pump is blocked off when installing the tube. Stock pick up is around the drain plug. This mod moves it back

[@datahop]

Whats the diameter of the tube? thanks. Great tutorial

[@TwistedGripGarage]

So in this video the tube we used was 1/4 inch outside diameter. I'm my stage 2 Oil pump video, I used 3/8 inch outside diameter for more flow. 3/8 is about the biggest you can do. Go check that video out too and you'll see side by side difference.

[@jakeb3025]

I’m another comment you said you did this same mod to a Takegawa High Flow pump, what size tube did you use for that? Looking at doing that to mine.

[@TwistedGripGarage]

If I remember correctly, it was .25 inside diameter

[@TwistedGripGarage]

Also, I have a video on the Takagawa oil pump mod. I dont go through the whole process but I think the tube specs are in there.

[@jakeb3025]

Twisted Grip Garage awesome, I’ll look it up. Thanks

[@TwistedGripGarage]

No problem, thanks for watching my video.

[@israelperez9103]

what kind of rtv sealant did you use?

[@TwistedGripGarage]

Permatex orange but you can use any that is oil resistant.

[@codyhorton2064]

Has anyone try this?

[@TwistedGripGarage]

I did...

[@lukeburritos]

1/4” inner diameter or outer diameter on the coper pipe?

[@TwistedGripGarage]

Outer

[@diet-water]

If you don't drain the oil and lay it on its side, would it spill out?

[@TwistedGripGarage]

Nope. The bike only hold a quart. Plenty of room in there for that to stay in.

[@rebelking4139]

thats the best way to fill your camshaft with gearbox rice

[@TwistedGripGarage]

Don't live your life in fear of the gearbox rice... lol

[@charle6843]

update on that oil pump modd! is it still good ? im thinking about do it it to mine

[@TwistedGripGarage]

Yes. I recently changed to a takegawa high flow with a bigger tube but I put 5k on the stock modified pump with no problem.

[@GoonRides]

Twisted Grip Garage can you sell me your old one??? I’m ready to buy it haha. DM me on Instagram @goonrides

[@bradthebiker]

What lenght of copper pipe did you use?

[@TwistedGripGarage]

About 6 inches. It doesn't have to be exact. Just needs to get to the back of the case.

[@mikeoberle6413]

Anyone checked the oil pressure during braking with this mod?

[@TwistedGripGarage]

I have not. Not sure about other people.

[@paulhartman7144]

Mike I would think while braking your not on the throttle wouldn’t really starve .but I do see your point . if you like to wheelie your odds are definitely better with this mod , if you don’t wheelie I would leave it stock

[@pebbleman-kw4jz]

why are you missing a part in yo engine

[@TwistedGripGarage]

What do you mean?

[@stevelubs]

Twisted Grip Garage think he’s taking about your kitaco no spinner

[@TwistedGripGarage]

@@stevelubs oh yea, I got ya. Lol.

[@TwistedGripGarage]

Yea, I'm running the Kitaco clutch cover. It deletes the oil spinner.

[@anthonyrodriguez371]

Why waste your time drilling and cutting when you can buy a pre made aftermarket oil pump kit for literally $60 online lol

[@TwistedGripGarage]

I enjoy the DIY stuff. A lot of people do apparently.

[@jbean530]

Pretty ingenious, actually. $60 saved is $60 towards a new helmet or other needed equipment.
