1st and 2nd are obnoxiously loud, third one is a bit toned down and definitely looks the best

The best exhaust set up i dont see. f2 thurst header costume exhaust tip made from. Gutted cut and welded stock muffler

The cdh66 is the best you have there by far ...i know it pulls better than those other 2 ...your motor sounded completely different it was so much better it revved better ... iv got one on mine with a shark silencer and it sounds really good it's really quiet and pulls hard 48mph it's fastest iv been 36t gear

2nd stroke motor + expansion chamber = Turbo (feelz like boost) Big expansion chamber= laggy but kicks hard when in powerband. Straight pipe= no power just loud... Lol

the third one because it is actually a 2 stroke exhaust with a expancion chamber, and a 2stoke needs a expancion chamber to get more rpm and run better.

More like 35-45 but yes😂

@@dreygrach no doubt mate i think its awesome and all my respects go out to you ive been meaning to get around to a build like this but time and money was never really playing along but its cool that i can still watch you among many others do builds and ride around

@@romanengelbrecht6717 Thanks man I appreciate it, eventually you'll get there, just stay focused on it and don't give up💯💪

thank you

Mine was never fully welded lol. Sounds good but I bet it doesn't perform like it should. Can't wait to weld it and see if it performs better

Yes I know and it back fires because I hold the kill switch for a couple seconds to let in extra fuel that lights up after I let go off the kill switch.

@@dreygrach lol why on earth do you do that lol wtf

@@ronniewilliz153 because its fun lol

Well yeah tuning it will be much better but I never really tuned it just for an exhuast🤷‍♂️

I had to put it on backwards to make the brake caliper work, it works fine, go check out my full review on the Motorbike, I got a video on my channel, I explained how I made it work.

Sorry no I dont have a video but I took off the cover on the bottom then cut out the welds using a small grinder (whatever its called)

@@JaxInni The kit for what, the motor?

Fully gutted, and thanks!

@@dreygrach how did you do it

@@dreygrach it got the welds off with a flat head and a hammer but having trouble on the baffle part

I usually just mix just by looking and pouring now but either 32:1 or 40:1, I usually have 40:1, its running a very little bit richer and my secret to the pops is right after a let off throttle I press and hold the kill switch for a second or two and let go and it pops, I got a video on my channel of using this same method but shooting flames.

Does this work on a 4 stroke bike kit

you dont

By pressing the kill switch slightly

Hahaha I guess😂

I just used a small grinding wheel idk whatever its called and cut out the welds

Made my own lol, take out the pedals go to home depot get a metal tube cut it and jb weld it.

Loud pipes save lives !!! Especially when you're on a motorized bicycle...

There annoyingly loud

They will have less power without the baffle

The motor is the one from Amazon/eBay but I got it from a friend and rebuilt it, I got a video of rebuilding it on my channel

He has one of the cheap ebay ones. I have the exact same kit and it works great 👍🏻

@@colesonfrieboes4755 alright cheers

A 20 inch kids bike, custom welded frame, check out other vids where I explain more about the bike.

That's what I'm wondering 🤔

20 inch kids bike, custome, got like a whole video series on this bike on my channel.

A bigger expansion would make more power in the powerband, but will take away more outside of it

Took out the pedals put in a bar and jb welded it lol, holds on super strong.

You can also use old bmx pegs and a bicycle wheel shaft

Its the stock exhaust I just removed the Internals

@@dreygrach so you just chopped it off and does it hurt the engine or is it bad because it’s pops and crackles so much but it sounds so good

Seen that you put it on towards the end nice

Oh yeah thats just a cheap version of an mz65, I'm not a big fan of it, but I recently got a real dirtbike pipe, will make a video on that so stay tuned!

Custome one?

If I strip the holes in the cylinder for the exhaust I just use a new cylinder, but using studs and nuts is so much better than using bolts, bolts will always get loose from vibrations, and thanks!

I dont know myself man, I've had that problem to, just get an aftermarket carb these carbs are built really bad and they will always leak.

That's the air bleed valve, sounds like its stuck

Take bowl off carburetor and clean bowl and needle valve under float. Must be a piece of dirt/gunk holding float open letting gas leak.

3 liter

Yea it was pretty tough but I took off the cap then used a small grinder and grinded off the welds as much as I could then used a flat head and a hammer on the welds.

@@dreygrach damm wtf so you basically broke that metal tube but isn’t it tuff aluminum

@@chaosaddictz0072 Yes, like I said it was pretty tough it was a long time ago I did this before I started youtube, I would have made a video on it, but I dont really remember exactly how I did it but I ripped everything out from there and man it sounds good tho.

Of course!

No they aren’t, these motors stock don’t have enough torque to get you going

Maggot Bin I don’t doubt that, but the stock motors even without one don’t have enough tourqe to pull the bike if you’re not pedaling.

@@jeffbruh3253 mine start with 2 people

Truth is yes but stock you’ll have to feather the clutch efficiently

Hahaha yep its louder in person.

Its a kids 20 inch bike just custom made😂

Lol yes, just clutching it.

Nope, I'm just clutching it in to make it sound like it does 😂

lol I'm just pressing in the clutch

Jackshaft kits do allow you to have gears, i had one but just got wiped by a car today, actually gunna see if i can get the motor and kit to still work tommorow, bikes toast, smashed forks and front rim, bent rear wheel forks, also beat to hell and bruised, 3 staples in my head lol, launched bout 15ft in air, dude pulled out on me

Also just for the record i did have right of way, dude left the scene too so im pretty much screwed aswell and a easily 500$ bike cause of jackshaft kit i just built to sell toasted, hopefully wont be a complete loss, couldnt get it to fire tonight :/

michael pendley how much are those jack shaft kits worth in A.U.D

@@meanderingmike7640 dayum dude glad ur alright 😳

I know right😂

Yeah I will probably be getting an mz65 later.

Push start lol, I had a pull start on it before but that chinese shi broke💀

Lmao🤣🤣

Its a 66cc thats what it actually is, but everyone calls them 80cc

All you can do is just take off the cap at the end of the muffler

Good idea

@@dreygrachyou can attach an aluminum soda can and it works as a muffler I tried it

I made this mod myself and it chugs the gas 😂😂

Yes, you mean the mz65?

@@dreygrach mz65 isnt a real dirt pipe it the best bolt on you can buy. cr80-85 eg is a real dirt pipe.

@@dreadknot2238 not a kx 65 is the og dirt pipe

Yuuup

No difference between them and if there is it’s not noticeable

Its just me recording lmao

So your saying its not restrictive??

@@dreygrach i am

@@killiansklassics me too🧐

I'm not a huge fan of the high pitched sound but its all in the crazy power you get from the expansion chamber exhuasts.

@@dreygrach While techically yes, for most cases it is enough to just do the ports, have a good spark, clean carb, sprocket change for a little bit of power etc. vs the pure stock. Personally I run exhaust from pocket bike, sound muffling is combination of small rubber pieces between engine fins, remote airbox (intake silencing), clutch pad mat, as well as rubber radiator piping used at the end of whole exhaust (and some general padding there and there). Helps it sound less metallic. Probably a muffler from bigger motorcycle at the end of the system could make even more difference, if I ever find more time to work on this setup, I will try to post results.

Да👍

😂😂😂 Idk, but thanks!

Just keep the stock exhaust, I don't think there is any other exhuast that is quieter than the stock one lol, but the stock one is super restrictive and not much power.
