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.
@@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
Tha first one sounds the best but the 3rd one looks great...and also it will put back in the rotation for a combustible power...great job on the build....👍
2 stroke engines always run better with a pipe that has an expansion chamber. The backfiring could be because it's running lean or maybe the exhaust gasket is leaking.
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.
Don't you have to tune the engine or carb before putting different exhausts on so it runs right? I took the baffle out of my stock exhaust and it ran right for a while but then died and it would not idle. I think there was not enough backpressure and I also had a bad air leak at the time so maybe it was that too.
can i ask you a question please?Why is your fork the other way round?Thankyou. Oh and i like the expansion chamber alot but custom pipe is good aswell.
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.
Can you actually cut the end of the exhaust pipe like that will it be ok to do that and can I cut it off with a Dremel disk and what does it sound like with it not being cut off and do you have a pull start on the bike
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.
The reason your front wheel wobbles at speed is that your steering fork is backwards...tucking in the rake angle is going to make it handle a bit weird...having the axle in front of the fork legs will stop the steering 'head shake' at speed
What kit did u buy I’m getting a new one cuz I brought a cnc machined cylinder head and my whole engine is milder together so I can’t replace the actual cylinder head
I see you have the thread bolts, but Ever strip the threads in the engine ( bolt holes) changing the exhausts? If so, any easy fix? I did, BTw, like a dumbass, lol. Nice tank!!
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!
Ya know the expansion chamber for the 66 is way too small of course that's where the power is rite so I went with a pro circuit expansion pipe for a ktm85 it cost but it's way better than any China made and another pipe that works well is a expansion chamber for a kx65 I got one on eBay works well all fun shit for sure and thanks for the vid
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!
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.
@@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.
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 :/
Damn, and I thought my mod sounded like crap ua-cam.com/video/XWR9Y2CoQXE/v-deo.html . I don't get it how you all want to make them sound like high pitched squirrels.
@@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.
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.
Which exhaust was your favorite and why?
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

Tha first one sounds the best but the 3rd one looks great...and also it will put back in the rotation for a combustible power...great job on the build....👍
thank you
The expansion chamber sounds the best I have that one on my bike it sounds good and looks good
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
I use the "Thrust" pipe, which adds a helluva lot of power in conjunction with porting the cylinder.
2 stroke engines always run better with a pipe that has an expansion chamber. The backfiring could be because it's running lean or maybe the exhaust gasket is leaking.

What rims and tires do you got on there. And where can I get a set.? So sick..
Can you actually cut the end of the exhaust pipe like that will it be ok to do that and can I cut it off with a Dremel disk and what does it sound like with it not being cut off and do you have a pull start on the bike
How are you getting it to sound like your shifting gears?
whats your oil mix ratio im damn blown away by those loud pops when you let off the throttle How do you do it? im sure its fuel related??
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
The reason your front wheel wobbles at speed is that your steering fork is backwards...tucking in the rake angle is going to make it handle a bit weird...having the axle in front of the fork legs will stop the steering 'head shake' at speed
What kind of engine is that? I know it’s a two-stroke but what is it exactly
How did you completely gut out that stock exhaust do you have a video of doing it
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)
is the first one fully gutted out or did u just remove the cap? love the vid btw definitely subscribing
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
Were did u get that tank from
Last one with a nice baffle would be best.
I like the last one. But how would you clean the oil out of it.
you dont
What kit did u buy I’m getting a new one cuz I brought a cnc machined cylinder head and my whole engine is milder together so I can’t replace the actual cylinder head
@@JaxInni The kit for what, the motor?
Is it shifting lol sounds like it or was it cutting out in beginning
Nice helmet where did you get it .
with the standed with no mufler how u make the rev limeter sound ?
By pressing the kill switch slightly
Isn't tye cdh the same as the other m65 clones
how you make it pop thata my question?
I know they have a lot more power when you remove the stock baffle, but it is loud.
Loud pipes save lives !!!
Especially when you're on a motorized bicycle...
There annoyingly loud
They will have less power without the baffle
Where did u get the foot pegs from cause I got a pull start
Made my own lol, take out the pedals go to home depot get a metal tube cut it and jb weld it.
You have balls to ride with one hand at that speed
Hahaha I guess😂
How did you completely gut out the stock exhaust like completely
I just used a small grinding wheel idk whatever its called and cut out the welds
what website did you get your motor from?
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
What bicycle did you use for that build?
A 20 inch kids bike, custom welded frame, check out other vids where I explain more about the bike.
Hi mate, do you know which engine you bought and where can I buy it from, also should I avoid £70 engine kits from eBay
He has one of the cheap ebay ones. I have the exact same kit and it works great 👍🏻
@@colesonfrieboes4755 alright cheers
I see you have the thread bolts, but Ever strip the threads in the engine ( bolt holes) changing the exhausts? If so, any easy fix? I did, BTw, like a dumbass, lol. Nice tank!!

Why no pedals?
The clutch slip gear changes remind me of Terminator 2. Lol
m66 pipe is better and you can get a silencer to go on it. front wheel was shaking a bit. try to see why. Nice looking bike.
What are you using for foot rests?
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
How much would you want for that exhaust if you can ship it to me I live in Cali
Custome one?
What size is the frame and wheels???? thansk
20 inch kids bike, custome, got like a whole video series on this bike on my channel.
You see that brass button on the carburetor yeah I pressed that and now it just won’t stop leaking please someone help me
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.
Ya know the expansion chamber for the 66 is way too small of course that's where the power is rite so I went with a pro circuit expansion pipe for a ktm85 it cost but it's way better than any China made and another pipe that works well is a expansion chamber for a kx65 I got one on eBay works well all fun shit for sure and thanks for the vid
A bigger expansion would make more power in the powerband, but will take away more outside of it
How many liters is ur gas tank
3 liter
How much for the exhaust that crackles sounds mint
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
Running a none expansion chamber pipe on a 2 stroke is just silly lol. But hey to each his own.
You need an expansion chamber even the cheap mz65 style pipe will make a big difference
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!
Why don't you have pedals?
Bet his neighbors love him
I love too pop the exaust... 🤣 Or when the muffler falls off and it flickers at night looks like a romancandle
Aye how did u remove the internals on the stock exhaust man it’s hard
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.
Are these motors strong enough to delete the pedals?
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
That 1st exaust is so loud my speaker and phone vibrated with the resonance!
Hahaha yep its louder in person.
is that shit even legal after you took the pedals iff
That's what I'm wondering 🤔
How big is that bike?
Its a kids 20 inch bike just custom made😂
Why such a giant fuel tank?
A proper pipe like a mz65 or actual dirt bike pipe with a 1 inch or bigger header feel free to check out some of my builds
Yeah I will probably be getting an mz65 later.
It sounds like your shifting but how
Lol yes, just clutching it.
How do you start the bike if you don’t have pedals?
Push start lol, I had a pull start on it before but that chinese shi broke💀
Lmao🤣🤣
Does this has gears
Nope, I'm just clutching it in to make it sound like it does 😂
How about you weld a muffler on the expansion chamber so it performs good and also sounds good
Good idea
@@dreygrachyou can attach an aluminum soda can and it works as a muffler I tried it
ASK THE NIEGHBORS WHICH ONE IS BEST...LOL
The f2 thrust exhaust is annoyingly loud! It's better than the stock exhaust but that doesn't take much cause of how much it sucks
some how you can make it sound less ? this is too loud for me
All you can do is just take off the cap at the end of the muffler
Expansion for me ❤
1:45 why does it sound like you have gears
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

I know right😂
Out of all times to eat sumn you choose when you making a video lol Jesus. Thanks for the knowledge tho! 🙏🏿
