Aside from pissing your neighbors off you're also going to ruin that engine bud. I know they're expensive but just buy an exhaust for it. Unless you want to blow it up of course then go nuts lol
I ride daily and work on motorcycles regularly, having no exhaust can damage your valves and the cylinder head. Very little of this happens on four strokes is, some of the combustion can happen in the few inches of your exhaust and it's better at transferring the heat from the engine. It's not safe to run an engine without the header/manifold for extended periods of time and really should only be done if you have to, like after rebuilding your engine or maintaining an engine that has sat for a long period of time
I heard that the dealerships were selling the grom above the MSRP.I didn't know that they were able to do that, but I have heard it from a few different people now.
yeahhh getting mine for about 2-300 over msrp mainly due to popularity. cheaper than my phone bill to own tho so definitely a good purchase , using it to make a stunt bike
Actually when I was 10-11yo I ran a Honda dirt bike like this for days/week. Put the exhaust back on and rode it for another 2-3 years now problem. I did it just to piss off the neighbors! 😂
No exhaust (at least a few inches) can allow cold (atmospheric) air to scavenge (via the venturi effect) up the exhaust port and onto/ past the exhaust valve. If that low temperature air touches the valve that is piping hot (600-1300°f) it WILL warp or crack the valve. (the same applies to the valve seat....
Throw a zoom loop exhaust and a dinger built titanium intake. Have a dhm stage one tune on mine. It sounds mean for what it is. I’ve had so many people flag me down asking what it is. It likes to backfire. Hell my brother can here me probably 4 or 5 blocks away
Haha reminds me of buddies 1983 Honda ATC 110 we called bubbles cuz it has no exhaust, sounded just like this with flames as well, great for trail riding in the grass and dry leaves, right
Do people not understand that every engine will “make flames” if you take the muffling off. That’s literally how engines work is compressed air and fire
Sounds like 🫧🫧🫧🫧 at idle
So did it gain or lose power??
@@Gazanova85 lose
That’s exactly what I thought.
@@proelitjump1355why would it lose power?
Bubble maker
I knew exactly what this was gonna sound like lmfaoooo spongebob sounding ahh
LOLLLL
Lmao imagine if it sounded like squidward walking!
😂😂😂😂
😂😂😂😂
😂😂😂😂
Bros didn’t do a straight pipe, they did a no pipe. Lmao
Sooooo long compression!
@@SirLancedHerLot7 Has nothing to do with compression.

RiP BoZo 🤡🤡🤡
That's not a straight pipe, that's a gay pipe.
@@fish_R_stinky69Yes it does. The exhaust valve can warp or fracture doing this which will absolutely affect your compression.
I hear the valves burning 😂
That's not how valves work bud
common misconception☠️ yall say the dumbest sht
Uhhhhhhhhhhhhhhhhhh😭😭😭😭😭

No back pressure any more I bet it would program awful untill it slowly dies
@@davidsautomotivereviews7673 Backpressure is worse for it.
I welded myself a real straight pipe.
@@fish_R_stinky69 tell me you dont know nothing about engines without telling me you know nothing of engines
@@bigshow196 Well, I know backpressure isn't good for an engine. That's for sure.
I love the sound of the piston sucking in and venting air (💭💭💭💭💭 sound)
does it blow bubbles too?
No pipe isn't straight pipe lmao,
Legend has the grom never ran again
That burnt valve calling
I recently changed my pipe and found this out it was hilarious, Everytime it's funny
U can Crack a valve seat that way. When u Rev it and let off it sucks cold air back in.
Sounds like them bee movie bee cars 😂
I was always told that would warp the valves
There is a possibility of it.
it can over extended periods of time…all engines need a little bit of back pressure to help the valves
Put it back on it'll hurt the insides of the head
and the inside of everybody else's head too
But what about the bubble sound?

@@Drayman1011 that's what I thought when I seen it burnt valves
@@Dragoneerengines need the back pressure provided by headers/exhaust to run properly.
@@DragoneerIt cools too fast
@@Dragoneer The exhaust valve since it is exposed directly to the air
Wonderful for back pressure!
Back pressure is a myth. Exhaust scavenging is what you mean.
The jetsons 😂😂
Wtf 🤣🤣 I wasn't expecting that at all 🤣
Sounds like bubbles popping🤣
The bubble sound got me 😂😂😂🫧🫧🫧🫧
I love these type of bikes you can do whatever you want to them and it's still fun
That idle fckn sent me 😂😂
She's a flame thrower 🔥🤣
Sounds much better with the exhaust
Bros got the bubble mobile
I heard that the dealerships were selling the grom above the MSRP.I didn't know that they were able to do that, but I have heard it from a few different people now.

You’ll do a lot of damage to a engine like that put it back on
Why is so? I do actually don’t know why
Na it needs some pipe on it it will be fine as long as cold air doesn't touch the valves
@@juanpablomagadan5296because it can burn out the valves
No shit. He did it for a video, nobody over the age of 6 would ride anything without headers
Actually when I was 10-11yo I ran a Honda dirt bike like this for days/week. Put the exhaust back on and rode it for another 2-3 years now problem. I did it just to piss off the neighbors! 😂
Fuggin jetsons mobile. Who remembers that sh!t?
Your gonna burn up your exhaust valve doin that
Imagine a fleet of these idleing at a light together
All exhaust shoot flames. Mufflers/CATs eliminate that. That’s why straight pipes and aftermarket exhausts are so fun, pops and 🔥
Bet it would look good with a half sized exhaust system
I just bought one. They are fun af 🤘

Sounds like it could be a kids bath toy! 😆😂🤣
Sponge bob bike? Lol
Now we know where the spaceship sound from the Jetsons came from.
My navi sounded the same until I tossed a cheap chinese amazon muffler on it. Bubble bike is awesome though lol

a mufflerless 212 sounds the same but better a 212 pair to that trans if itd fit itd be a lot faster n more torquay
Oh God, it sounds like the bubble sound effect or someone after they Taco Bell 😂
Sounds like that bubbling sound when a kid puts their lip together to make various noises or it's take a hit off a bubbler
I have this exact Grom with a zoom exhaust and it backfires when I try to ride soft. Why?
Shi sounds like its blowin bubbles
Good way to Crack piston
Shit sounds like an underwater queef
Haha reminds me of buddies 1983 Honda ATC 110 we called bubbles cuz it has no exhaust, sounded just like this with flames as well, great for trail riding in the grass and dry leaves, right
Do people not understand that every engine will “make flames” if you take the muffling off. That’s literally how engines work is compressed air and fire
Sounds like my four wheeler 😆
Mine sounded the exact same when I took it off😂
Its gonna run rich as hell
Sounds like my cammed minibike
I was waiting to see bubbles flying out.
“It’s shooting flames” yea no shit there’s explosions right fucking there
its sounds like pop cat when it idles
bro took the whole pipe not just the muffler tf😭
Soulds like the krabby patty mobile😭
Sounds like the bee movie cars
I heard my friend make that exact noise last night
Exhaust valves are just a suggestion
It MaKeS fLaMeS.
It's so weird how internal combustion engines do that.
Piston rings leaving the chat
Absolutely not
@@danielfrazier840 says the person who doenst know how to work on engines
Valves left the chat
Bro it sounds like the cars from the bee movie
Listen to my grom lol
Out here whipping the not so invisible boat mobile
You taking off the exhaust will make it go faster tho lol😂
Pretty sure they all say u cna burn an exhaust valve doing that
Ya that thing wont run 1 minute that way
youll warp those valves fast.
That’s gonna blow your valves to heaven and make the tune shit
Grom people are a different breed..lol
Great way to warp a valve and/or valve seat.
Ur gonna cook the valves
Squidward when he walking around the kk
used to have a 125 moped with no exhaust it also shot blue flames out the bottom
it’s only making flames because the combustion chamber is like a centimeter further down the hole
It sounds the way it looks lol
Its a single cylinder. Its always a straight pipe. Theres no second pipe for a H or X pipe
Bro that bike is done
Stock sounds like my crf80
Someone explain why this can damage the valves
Sounds like it runs on flubber😂🤣✌🏽
The term straight pipe does infer a pipe still needs to be there
Exsaust valve is leaving chat lol
One speed bump sending you to God
Love it
After years I have found the source to the sound
have fun with the two days you have with it running your going to wreck your headers and blow it. Hell of a rebuild for ya
Sounds like spongebob to me
Get a lifan kp mini 150 cc it’s a 5 speed carbureted I have a 28 mm nibbi carb and a kpm 200 front and mid pipe and it spits fire
GeeT way to blow it up
The bubble bike
That will blow the top end
Most engines under 1000cc sound like this when it’s straight off the block. No compression after the combustion
Sounds like me in that 🐈
So uhhh back pressure straight out the bottom end huh
Bro sounds like SpongeBob's burger car😂
Also need to rejet
What kind of Grom is that?
