great video i have the dhm 186 as well and went to the 16 tooth front sprocket its smooth still has torque but struggles going up hills. im going to go back to stock gearing.

gotta say, love the wrap on your bike

Great video man!!!

I love the colors in this bike

Very nice, thanks bro

Nice video mate. Did you get a street port and bigger valves on the head? Also, are you running a koso 34mm throttle body or did you stick with stock?

hey dude, I'm on the line about purchasing a grom. Here in Chicago, I see a lot of people riding them, and they do really look like a lot of fun. I owned an older CB400 and I liked it just because it was really nimble and just really snappy. I just don't know whether or not I''d enjoy the Grom. I was thinking about buying an R6 as well, just for fun. Most of what I do is just ride around. Got any feedback? Was it worth the purchase for you? I''d also like to ride around the suburbs and usually the speed limit is around 45, so I just want to know if shit is also capable

@gromerman Do you think you could stand it up after a stretch and lower with the 186cc BBK?

Did you replace original front fender n if so what is the one you have now looks nice.

Hi, question for you. I have installed a big bore kit with ecu flashed by DHM. I for some reason cant even get up to 62mph. Not sure, I am thinking to resend the ECU back to DHM see if they can re-flash it. Question is after installing the kit with flashed ECU did you perform the ECU and TPS reset? And did you install a new updated injector for the 186cc kit? Thinking of getting a power commander for it do you recommend a good power commander? Not sure if its worth it. Please let me know your thoughts. Thanks!

Hey man, where did you mount the kitaco catch can to? I’m having the same issue with a cage

I'm here in idaho falls! Love riding my grom around here. Keep an eye out for me blue grom bright orange jacket.

may i ask where did you go get the anime decal on the side fender for your grom? thanks

I see you are a man of culture as well.

Nice👍🏼 my 2021 (2022 in the US) Grom do 65 mph stock. Wonder how much gain the new engine makes plus the extra 5th gear🤔

Huge favor to ask...could a group of you ride down to Black Foot and have some Rupe’s for me? I live north of Portland and a drive out there for a malt shake and a badass burger isn’t something I can do. Keep the videos coming man. +1 SUB.

this is ths same 125 motor thats now in the Trail 125 correct? So all your upgrades would cross over just the same...mostly. Might give it a go.

Will the 5 speed tawagawa clutch be compatible with this 183cc DHM kit.?

What gear ratios & clutch are you running? I just ordered this kit & stunt the mess out of mine so I'm just curious.

who wrapped your gorm? i been trying to find something like this

Where did you get the anime wrap tho thats so dope

I don't know if it's the mic but it's sounds like your timing is off in the top end, you should also be seeing 80mph+ with that kit.

You have the oil cooler mounted upside down? Is there any cons to that? I hate how 'low' the cooler sits.

Love the anime graphics. How or where did ya get that??

Where did you get your graphics?

I love my little Grom. I have about 1300 miles on the stock parts. I'm going to wait for the warranty to go out before I change it up

Did you get it like reflash for Dyno tuned or whatever?

Do you have an oil pump with an extended pickup tube or just a high pressure oil pump?

Where did you get that front fender? Been lookin

Does the oil capacity go up from doing a big bore kit?

So any issues with this? How many miles have you put on it? You should do an update video!

Yeha the next step on my Grom is definitely a big bore kit!!! Enjoy the Grom life mate 🤙

Did u have to upgrade ur crank when u did ur 186 bbk

What gps app are you using to get your speed on your phone?

Where did you get the prefilter from

what type of paint did you use? looks sweet!!

Quick question 🤔 I have the same kit as you do, but once in a while it doesn't start on first try. Do you have this problem with yours? Someone said it is because of where the piston is at cause of compression.

Is that all you need to bore it? Or do you need more like a throttle body or anything else?

Where did you get the filter cover?

I’m 15 don’t know really anything about motorcycles but I’m trying to get mine to do 74 how’d he get his to get up to 74?

hey i just also finished up my install of my dhm kit, i was wondering what spark plug did you use and what did you gap it at?

So did you use your stock head and stock cam

The new 23/24 groms can get up to 70 mph I wonder how much faster they will go with that kit

Do you still have this setup currently ? Is it reliable

Great video, how’s the reliability since it was installed?

Can U still stunt it after going back to the stock motor? That's the REAL question!🤪

Do you have stock sprockets?

Hows it holding up?

How do the Groms ride on the highway? Are they smooth or do they feel like you are cheating death?

Yeah I care about acceleration too on this grom cause like you said if your worried about top speed you need a bigger bike👍

Not to mention on going on 14k miles and I only got a 14t on the front and Rear is Stock my little grom can go places lol

I counted a 4 second gap between the dhm 186 grom and the dhm flashed/cammed grom 😱

What altitude are you at? I'm up as well

What front fender did u use??

What sub-cage on ur grom?

Where can i get graphics like that?

Are you in idaho falls idaho? Gotta let me know when there is a grom right

How much faster in top speed is this then stock

How is the gas mileage with new kit?

Hey what is a good setup for stunt on a 186!

how’s the dhm kit after a few years now any issues ?

I get 118km at 9000rpm on 2020 ,airbox 15 /38,no other mods,,siting up and thats it,,and its still a grom ,,

Saw 74mph damn dude that’s awesome👍

where did you get that handlebar pad?

34mm tb an ported head from dhm thing would scoot out well shit gets spendy fast

I’m stock grom only intake and Exhaust and I’m topping out 74mph on freeway lol how’s this big bore only doing so much ? I thought it be hitting 80-90mph atleast dam

Last time I did a full tuck, my ole lady yelled at me

Are you in Cali?

What did your stock MPG go down to?

Stock crank and rod?

Do you have a straight up oil pump?

72 73mph??? I get 78 on my grom and only intake and dinger exhaust and flashed ecu

Where did you get your graphics

Dear God... I had hoped that's what it ran like stock! They need to make these in a 250.

how much do u weigh

I don't get it, I have a stock motor with ixil exhaust and a stock intake mod... 14 front and 36 rear sprocket, and I hit 73mph on my bike. For whatever reason my bike is faster than all my friends and it's a nearly stock '19.

only think i dont liek is that high front wheel fender. i have seen better high options.

WTF! That’s a Toys R Us! They have been closed for several years now!

I want a dont fucking die sticker

I’m hitting 74 with just a tune and intake

That can't be right. I just went 115 kmph on a stock 2014 GROM.

Dad

Sounds like its bogging

Good video, I like it! BUT.......You never said........HOW MUCH! LoL!

About as fast as my old Suzuki K50 moped with 100cc less 😜 They should've made it a 2 stroke instead but I guess the climate-talibans put a stop to that.

Dig the grey but uhh... The nude anime girls... Like bruh....

I wonder why literally every American leaves their high beam on while riding... In every Grom video in the USA you ride with high beams on. Why???

Still looks super slow sadly

Stop chopping your throttle

my china bike is faster than that lol

Look up Cocks Stuntparts They Have Amazing Cages
