2023 Honda Grom DH Motoring Cam, Chimera Intake, ECU Tune, Sprocket Install | Test Ride Motovlog

[@phillythakid]

Might wanna recheck that valve lash brother. It’s sounding a little chattery on the vid.

[@sethsimmons6638]

You do not need to slip the clutch on every shift like that man! You are going to burn your clutch out prematurely riding like that if you haven't already. You only need to slip the clutch to take off from a stop, you can actually just let off the throttle for a split second and upshifts without using the clutch, it's smoother and easier in the trans/chain/sprockets

[@BigBoyzToyz1974]

You change gear a little strange 😅 it like you don't let the throttle off a slip the clutch

[@asheredwards9506]

my grom topped out at 78 mph 9200 rpm in 5th downhill all stock. went to 13/41 sprockets and top out at 72

[@Rayan-rw3gt]

what do sprockets do?

[@asheredwards9506]

@@Rayan-rw3gt they are the final drive. like on a bicycle different sized sprockets (gears) change the amount of power rotations to wheel rotations.

[@christopherbassit6896]

Stock I went 81 and bounced 5th down a hill. My friend too

[@Schwing27]

Kinda sounds like your clutch is slipping a bit when you are shifting on those high speed straights.

[@xChewyV]

My gps tracker on my phone clocked stock sprockets and everything all stock to be 1-2 mph less than what the speedo says. With 14t front sprocket at 45mph it reads 5 mph less and at 56 it reads 6 mph less. I'm assuming at 70 you're probably 7mph slower than what the speedo says

[@outbackdiecast6730]

I love it man I got the same exact bike. Definitely didn't buy it for speed but I wish I could go 70 at times. I top out about 64 stock

[@Matt_Yniguez]

64 is still fast for a grom!

[@MrZachgonz]

I’m at 62mph on flat ground with my SF Grom. I weigh 230 though so that’s probably why.

[@Matthewb20]

I also just bought one but I already have some experience with groms, I specifically bought mine as a fun little get to work and back type deal and if your behind a car you can use them to your advantage to get up to 76 or so mine’s completely stock and I hit 76 on the way home from using a cars wind draft

[@baldbeardedx]

Stock can be off 4-5 at 60. Dropping a tooth your probably less 6/7 at 60

[@julianchong3912]

Question if I don’t want to waste to much or do it much to my grom Do you think the Yoshimura exhaust rs9-t, dhm performance ecu flash, and chimera air intake is enough? If so would I need to do anything to the grom by adding these parts ?

[@ghettosled1976]

They’re all easy jobs and will get you having plenty of fun. Honestly if you’re going to do those, get the cam right away and the flash that goes with it. It’s not super hard and it was the biggest gain I noticed on mine.

[@hartfordraces]

I'm planning on getting a grom. Can't decide sf or new one. Ps nice ep3. Got a black one as well. K24 turbo. Just got her running the other day

[@Matt_Yniguez]

I'd say new. They're cheap even for a brand new bike! And nice car!

[@2AM_Garage]

I’m pretty sure your speed is accurate, it’s when you change the wheel size, that that should make a difference because your speedometer is in the wheel.

[@Matt_Yniguez]

Gotcha! Thanks for the info brother 👍

[@2AM_Garage]

@@Matt_Yniguez 💪🏽

[@2AM_Garage]

@@Matt_Yniguez OK I just learned something new, I was informed that on the Honda Gramz, that your speed sensor is actually in the crank case or something like that, so it’s not the front wheel. So apparently you have to purchase some kind of plug-in play system to accommodate for change in gear ratio.

[@MrPond-xp6dl]

Mine is always reads 2 over when I go past a radar

[@ilyxuan_]

can you do a parts list w/ links

[@phunkdoctaspock]

He likes your comment but doesn't actually do it... Ok.

[@jeremypierce1979]

If I was you, I’d get rid of that chimera intake and go with a man in the box and take it so much cleaner luck doesn’t have that wire that could short out a lot of people put it on those newer models check it out

[@Matt_Yniguez]

I'll check it out thanks! 👍

[@bikebilderbear6786]

Pretty cool video. I'm topping out at 70mph with my 2021 boom vader clone 4 speed. I did add pwk power jet carburetor Z40 cam and springs/ Ported and grooved the head / Hand made header tube to high performance canister with a 17t. You got a sweet bike there.

[@Matt_Yniguez]

Sick! Thanks a lot!

[@jeremypierce1979]

Do you want the baffles removed? I have a Vance and Hines exhaust on my grom to be heard from people, so you don’t get run over wear earplugs in your helmet if it’s too loud, that helps

[@usmcmsgt5487]

I'm looking forward to doing pretty much the same thing.

[@remyche8768]

Hey grom folks, I have stage 1 flash, for exhaust and intake, and putting a dhm cam,.should it be fine to ride till I get some else?

[@Ezdrumms]

all I want to do to mine is ecu flash, exhaust, intake and sprockets. Is there anything wrong with that? Do I have to do all the internals to make it safe or am I good with previously stated mods?

[@Matt_Yniguez]

Those mods are good enough 👍

[@Ezdrumms]

@@Matt_Yniguez thanks for the reply bro!

[@904outdoorz2]

Did you adjust the valves ? Sounds like they need adjusted

[@droneartists6137]

I dont think the speed is displayed exactly anymore when inserting the 14t sprocket, so your reading is off bro

[@2AM_Garage]

Nice! It almost looks like you’re out in Arizona. I’m waiting to install my intake, and waiting on my ECU to arrive in the mail. I’m gonna run it with just intake, exhaust, and ECU then see where I’m at. And I imagine I’ll be going for that camshaft next. Good video.

[@Matt_Yniguez]

I'm actually in the high desert in Cali. That's a good combo to start with!

[@Dragonstorm1557GAMING]

Hi there, I'm looking at getting my ecu tuned for my 2023 grom I've got a kemimoto exhaust and I'm planning on installing a k&n ha-1222 air filter. Curious to know how your doing!

[@2AM_Garage]

@@Dragonstorm1557GAMING mine is doing great. Tune ECU is worth it. And the intake and exhaust. I end up putting a 39 tooth rear sprocket on, now it lets my RPMs hit almost 9000, TopSpeed has increased and so has to torque

[@DiogenesOfCa]

@@Matt_Yniguez Apple Valley is my guess.

[@JesusDeAnda-pc4hn]

​@Matt_Yniguez bro I know I recognized Santa fe and the 138 I wasn't trippen! I hope you still have your grom! I just got mine slowly doing mods. But wanna get people together for cruising up here.

[@GhostTheSigma]

Was that the only 4 mods you put to reach 70mph ?

[@kimyeahph]

😍🏍️ be safe on the road!

[@Matt_Yniguez]

Always 😊

[@antonioperry9585]

In my neighborhood. Looks like you're riding right around the corner from me hit me up if you want to do a project?

[@royalknight4742]

What was your price for all that?

[@David-nv8vu]

By the sound of it, you may need heavier clutch springs .

[@ghettosled1976]

It’s his terrible shifting ability lol.

[@AttentionClouds]

Do you have the links to the parts?

[@anthonymoy4471]

What license plate bracket do you have i ju s t bought the same 12 bar ?

[@Matt_Yniguez]

@anthonymoy4471 i can't remember if it's TST Industries or if it came with the Toce exhaust

[@anthonymoy4471]

@Matt_Yniguez is it ajustable or is it fixed in place it looks like the tst high mount or ajustable

[@Matt_Yniguez]

@anthonymoy4471 it's not adjustable

[@357bkg]

I know it’s late but u need stiffer clutch springs

[@RichUp-z9u]

yes he does need that

[@User-kb1tq]

Do they ship to Europe too or usa only??

[@Matt_Yniguez]

I'm not positive, but I think they do! Give them a look dhmotoring.com

[@mikebaker2522]

How did this affect you mpg?

[@ghettosled1976]

I have the same cam and flash with intake and exhaust as well as the 14t and I’m still around 105 miles per gallon and I’m 230lbs. I was surprised. Thought it would at least drop to 90

[@PrelandRanger]

What exhaust are you running man?

[@Matt_Yniguez]

Toce

[@mariohernandez6733]

Can you install that exhaust without that wheelie bar ?

[@Matt_Yniguez]

Yes

[@baseballfanatic110]

If I get exhaust and air intake will I need to tune it?

[@Matt_Yniguez]

You don't NEED to, but it's highly recommended to.

[@lavishlex]

Can you run a mid faring with that air intake?

[@Matt_Yniguez]

I've looked into it and I don't think so tbh

[@lavishlex]

@@Matt_Yniguez would you have to cut the mid faring or would it not fit at all

[@Matt_Yniguez]

@lavishlex the fairing isn't what's in the way, its the air intake

[@tonyromo4778]

You probably going 58 14t sprocket is off by 7 or 8 mph unless you have speedo healer

[@Matt_Yniguez]

Don't you mean 68* then?

[@tonyromo4778]

I had the 14 t, and I was over 7 or 8 mph on my gps

He’s power shifting, meaning he’s not letting the throttle go before shifting, which will tear his clutch up
