So a few months ago I caught wind that either BTX or StandardFunctions (can't remember which) was bringing to market an intake they had designed specifically for the Grom. It was made of hard piping, had a provision for the air intake temp sensor and was topped off by a UNI Filter.

When I was considering ordering the intake I had to deal with Ming of Standard Functions. I had a few questions about the intake (does it have a AIT sensor provision, better pics and install instructions, etc.) so I emailed Ming. Getting the questions answered was like pulling teeth with this guy. He finally let me know that it did indeed have a provision for the AIT sensor, he had no pictures aside from one small Instagram picture collage and there were no installation instructions. Fair enough. Against my better judgement I ordered it anyway.

The intake arrived soon enough. I opened the box and was impressed with the intake. The welds appeared sufficient, there was a mounting tab and the finish was nice. There it sat for a few months. Fast forward to today. I went over to a banks619's house and took the Grom body panels off to fit the intake. I put on the rubber piece that connects the intake and the throttle body. Then I went to attached the intake. It was quite a task to get it just right so that you could put it in the coupler. Once inside the coupler I noticed that the mounting tab was just hanging out in the open, not near a mounting point that I could see. So banks pulls up a picture of the intake installed on another Grom. To get the mounting tab in the right place you had to bend the coupler in a way that I was not too comfortable with. Nothing much I can do, just tighten it down and hope it stays. Now I have the mounting tab in the general area it needs to be, but there is no way to get the mounting tab in the right spot without actually bending it. So we bend the tab and bolt that up. Time to slap on the filter and check my fitment. The filter position is TERRIBLE! Not only do the forks compress the filter at full left lock, but the horn in the stock location contacts the filter on left hand turns. So you have to bend the horn as far out the way as you can in hopes that you do not rub a hole in the filter.

On to the ride report. The sounds of the bike is much throatier and I feel like the bike has a little more pep than before.

Overall the quality of the intake is good. With so many minor issues I am kind of perturbed with it. The issues are so minor they could be easily fixed if the maker actually wanted to. I am going to see if an angled UNI Filter will do the trick or possibly see if there is a shorter filter.

LateNA,

It may be just the way i read, but it doesn't sound like you are very happy with this "Designed for Grom intake?"

Would u recommend for us to wait for another vendor that makes one that actually fits?

Geez and i thought i sucked at using my caliper!!!

Do you have photos of it installed on your bike?
I wouldn't call those problems "minor issues". The mounting tab not lining up and the filter being crushed/compressed by the forks and horn are big problems.
Who cares if it looks good? If it isn't fit for purpose, it shouldn't be sold.
Sounds like someone needs to re-design it.

Yeah it seems like if they took just a couple more days to tweak it it would be a very good piece. He had to totally bend the horn to keep it from touching the filter. The forks still touch it and when it was attached to the upper mount and slid into the rubber piece that attached to the throttle body the rubber piece was all misshapen due to the angle of the intake.

You read that correctly.

I completely agree. But that is the price we pay for being an early adopter of parts. So I am going to do what I can to make it work.

K&N directly on to tb.. All problems solved and saves you like 150$
That is an option but I have always had less than stellar results when mounting filters directly to carbs or throttle bodies.



The good news is that I was able to find a UNI Filter kit that has two filters that are an inch shorter than the one I am using so I ordered it and hopefully that will fix the problem with the shock hitting the filter.

I appreciate the review guys, and I stand behind the products that we sell here at StandardFunctions.com

As far as the fitment issues, I've installed plenty over the course of the months. all of my projects and customers lined up perfectly granted the fit is a really tight one, I'll say that much.

The filter does run a bit long as BTX provided but it was never an issue for me since the contact is very minor and the foam filter will "flex" with contact WHEN the forks are fully turned to the left. (which is really when its parked unless used on a stand of course :peaceful:.)

How are you liking the overall feel of the intake installed?

I for one love this and it plays a major reason to why I even carry this product. The feel at every gear for a 125cc engine, is exactly why I bought this kit for myself. The throttle response is just right and the overall length and design plays its part over a simple airbox removal and filter "slap". I ride with many grom friends on a weekly occasion and lets say this mod compared to a stock air box, has its advantages :blackgrom:

I agree with Minkus.

I also have this intake and it was a Very tight fit. I did not need to bend anything and it fit perfectly but it is tight. It doesn't hit my horn in the stock location. The only issue is when the bars are fully turned left while parking it rests on the soft foam filter. Not really a deal breaker for me.

The intake is MUCH nicer then the air box mod that I did before. I noticed gains across the entire spectrum and a higher top speed.

I just want a velocity stack or something to get rid of the foam filter later on since I am not a fan of the UNI foam filter.

Otherwise, great product and a stand up guy that makes them.

Well when I installed it I had 3 other guys there with me. I still have the plastics off for an HID install, so I will take a second look at it in the next few days. My main concern is the flex on the coupler.

I enjoy the build quality of the product and the performance, as stated in my initial post, feel free to check it out.

Once installed, I cant see why there would be any flex as this will sit stationary once the couplers are tightened in place on the throttle body, and the aluminum tab is bolted up to the side of the frame.

Feel free to review my pictures and let me know if you see anything out of place.

Feeling that I may have overlooked something I took the time to go out to the garage and take the intake off and then, only putting the mounting tab on the correct side of the backbone, put the intake in the coupler and tightened it down. This is the result:

Logic would dictate that if anything the intake should sag when not attached. Instead my mounting tab is to the rear and above the mounting hole. Help me out here, because I must be missing it. If I make it so that the mounting tab lines up then the coupler will obviously be flexed.

I didn't find any issues during the install. I lined up that screw on the bracket first and put it on loosely then installed the rest of the intake and then tightened that screw.
