Trying to watch this this bad wifi almost made me throw my phone and leave a nasty comment but i've calm'd down and now appreciate the video and good information. People on the internet forums said the cheap expasion chamber sucks but this proves otherwise. A great upgrade for 30 bucks
I really would've liked to hear a sound comparison between the different exhausts. That would've been more useful for selecting my new exhaust... I ended up ordering the Voodoo
Hi, i know im lait to this party but this has goto be the best video ive seen of 2 stroke exhaust system's! thank you mate take care and have a great day!
How are you only maxing that engine at 29? I got thirty on a stock exhaust and without doing any tuning to the carb. Then upgraded to a expansion chamber and did thirty six miles per hour. Is the engine not running right? Is your fuel not mixed properly at the right ratio?
I like my banana pipe AFTER i modified it because its a very high RPM pipe stock, I added over 1' to the header and enlarged the stinger to 13mm because stock size was too restricted with a 10mm stinger so now its in the 60-63% range of the header I.D, with the extra header length and stinger enlargement the pipe kicks in way harder and sooner around 4,000 RPM's and pulls to about 8,500 RPM's with and rev's out to 9,500 RPM's . I also had the big Bertha pipe and the header was way too restricted so I cut a stock header off of a stock Muffler and welded it on the Big Bertha was a great top-end pipe because the Stinger was way too large on it and needed reduced to about 13mm as well to have more low-end, but it was a good pipe I liked it because it had my bike revving over 11,000 RPM!
I run a f2 thruster, good pipe, although build quality could be better, I had to clean it up. Although in its original form it works quite well, I suggest wrapping it in heat wrap though ( if your like me and wear shorts). If like to ride long distance wear ear pugs if you’d like to hear after a ride.
Sorry for my english... In our country (Slovenia) people are tuning their 50cc mopeds and motorized bikes to achieve over 100kmh (62mph) from original 45kmh (28mph). One guy tuned his Tomos moped so much that he was able to achieve almost 150 kmh (or about 93 mph). He was driving his moped on a highway but this was an extreme example.
That's what I want to do I had a 49cc caglari Daytona with a bore kit on the engine and tuned the engine as much as I could and built it as much as I could and I had it doing 80 mph fully topped out
BikeBerry, you guys rock! I get most of my parts and accessories from them...My latest was my 3-spoke Mag wheels which are still performing perfectly! Thanks, BBR!
I'm curious to know whether the bikes were properly re-jetted before the test or just slapped together and run in whatever shape they turned out in. Everything you change on one of these mouse motors affects the jetting in one way or another.
If you want higher top speed get a smaller sprocket like a 36 tooth and if you want more climbing power or more low end torque get a larger sprocket but you do sacrifice top speed for more acceleration. You could get a jackshaft too if you have a mountain bike I find them better because you get more gears and you don't have to worry all too much about chain alignment and sprocket adjustment
@Bikeberrycom The test on 4:30, The lower left hand corner, which exhaust system was it? I like how it doesn't have much white smoke coming out and it seems like it's one of the top performer.
My 80cc anbull motor I modified the stock took off cap and put straight pipe on it and the seal was broken on the engine to exhaust and the rpm was crazy high while bike was idling I took off from almost a dead stop and pop a wheelie almost a foot high it was hella torque and top speed it was unbelievable I was going around 40mph top speed and super fast acceleration I was amazed and I did on accident by the seal being broke cuz I fixed the seal it was totally different and slower after I fixed the seal
The broken seal was allowing unmetered air into the motor that is also unfiltered. It was causing a lean air mixture to enter your combustion chamber thru the exhaust at the cylinder connection that was leaking.it will destroy your motor so dont run the motor like that.you probably did damage the motor already.thats why it runs different now as you say. Your air mixture is probably to rich to begin with tho
Why does everyone of these engines have the metal on metal clinking sounds to em.i just put on another gasket to try to stop it gna wait a couple more hrs to test it but I dnt want to lose performance 🤔
right thise rims should be maken those bikes go 45 mph thay have a 36 tooth sproket thats all mods you need i like 40 tooth my self kits come with a 44 tooth
Hello to all motorized bike riders all exhaust systems present or sold no matter who sells them. I can tell you that I myself tested each of these muffler you will just spend money for the look there is no performance to draw from that. I took the standard muffler and cut it in half to beat all the performance of its muffler sold on the net. That's going to change because this spring I'm going to sell real exhaust systems that will allow you to get 50% more torque and top speed then watch the sleeper ED site. this is where you will be able to order a real performance system as soon as possible. Sleeper ED
This video was fantastic until you included starting the engine in the test. It doesn't make sense to include pedaling and popping the clutch because none of that relates to the muffler. Just go 0-20 from idle and stopped, shooting for consistency with the power application. We're talking about differences of fractions of a second, don't include 5 seconds of human error at the beginning.
Ya know I don't really mind if I waste fuel. Got quite a few of those mufflers and just not right. I'm running a cut chamber and richened it up, Dio reed valve ported head oko setup from y'all. Several coils but running a stock one without a flywheel key so as to advance the timing just a little more. Base plate spacer, machined head for cooling and slightly higher comp, bottom end completely untouched besides the clutch components. Rolls 9500 rpms at 45mph. It'll go faster but I'm not trying to throw a rod. Stock rear sprocket, 1500 miles on it. 25:1 synthetic oil mix ever, 1 break in plug change, 2 clutches, 2 bucking bars, balls, and clutch covers, ordered a front sprocket from y'all never got it, 2 chains, 12 rear 27.5" tires. Bad on gas though. I'm surprised that that front sprocket hasn't let loose yet, the teeth are toothpicks... Might just order 10 so I can at least get 1 of them. I'm 250 lbs and growing.
I have a Performance Speed Demon exhaust with an expansion chamber and muffler from my 49cc on my 80cc upgrade. It worked wonders on my smaller motor and can't wait to see how it performs on this one. Still got a few more things to do to my new motor before I can take her out for her first start-up. Hopefully I can upload her first start video.
Top speed 29 mph? I can do that with a modified stock exhaust. Are you testing with 50cc engines? My builds run between 35-50 mph, whatever the customer wants. Bikes by Bill.
why do you sell rubber motor mounts but never use them! i feel no vibration at all on bike! at first i didnt have them tight enough and it was terrible but after tightening them tight as gerbels ass there fine!
Dont put an expansion chamber on a 4 stroke. Waste of money. A 4 stroke lives from the size of its inlet and exhaust ports, size of the carb and compression. As long as the exhaust is free flowing the engine will run great
Weights of each system was not included in the video. We focused more on how they impacted performance vs each ones physical specs. If you'd like more on that you can check out the product pages.
I believe that starting the motor, and then going to the starting line, followed by accelerating without any pedals whatsoever would have been more consistent.
Agreed, there are some things we would tweak and perfect in the future. We try to provide as honest as possible information but we also acknowledge when we can improve.
NerdyRdneckGamer I'm pretty sure I'm going to buy a motorized bike motor and install it. But I didn't know you could go from a stop without pedaling to get the bike moving. Somebody said you can't. I don't see why you couldn't.
@@jonsmith2217 So if you start the bike before hand there isn't any problem going from a dead stop with only the motor. Just ride the clutch for a moment.
The stock exhaust is not even made for a 2 stroke. If you have some fabrication skills get your hands on A. Graham Bell’s book: Two Stroke Performance Tuning. In this book you will find everything you need to know in order to build a pipe , to fit your engine, like a glove. Built my own for my style of riding and is perfect.
I do 42mph on my 66/80cc china girl stock engine with stock muffler. No silencer tube but maintained the bottom cap. Stock speed carb with no air filter. 40 tooth sprocket and a mini spark plug model L7T.
Don’t give into to advertising techniques. First and foremost you’ve got to remember there’s a lot of beginners who don’t know that much about these engines and they will fall into temptation and buy one of these pipes. I personally have tested a f2 pipe and it doesn’t compare to a slightly modified stock exhaust. Do your research and get what’s best. None of these pipes are going to be good
@@motorizedandrew3942 What did you do to your stock exhaust pipe to make it better than the F2? I sawed off most of the stinger from the cap and it didn't seem to do anything. The acceleration feels really slow. If I take the cap off the bike comes alive and I can feel the acceleration, but it's so damn loud it's not even fun to ride on the road.
@@mad_scientist5597 take a soda can and some steel wool. Remove said cap and replace with soda can and steel wool. Btw just remember to drill some SMALL holes. Nothing too big but you want lots of holes. The exhaust will try to push the can off so use a hose clamp and make sure flow is good
@@motorizedandrew3942 What's the difference between doing this, and just cutting the stinger and drilling holes in the cap itself? And what's the steel wool for? I don't have a lot of experience with this stuff so I wouldn't know
@@mad_scientist5597 the cap technique is really iffy. Some engines will benefit and some won’t. Just removing the chamber inside or what you call the stinger isn’t enough. Drilling holes in the cap also makes it sound like trash. I have never liked the sound the 2 strokes make with the cap holes and chamber removal aka sleeper mod. The steel wool is to help with sound detonation. Although be careful because steel wool can ignite. Fortunately steel wool won’t really burn it will just create a bunch of little small sparks and then turn into nothing. If your engine gets loud then you know what the issue is. On most lawn equipment 2 stroke engines they have a little screen in the exhaust called a spark arrestor. It’s job is to make sure spark don’t fly out. The real truth is it’s mostly an epa thing. Spark arrestors do have a place tho. Generally a well tuned engine isn’t going to create sparks. I’m a 2 stroke since the exhaust hangs open in the upstroke it will let some unburied fuel mix out. Now if your not well tuned and you have pre detonation going on it will create sparks going out the exhaust. To sum it up… you should be fine with steel wool as long as you don’t have pinging or pre detonation or excessive 4 stroking. You will have to tune your carb because you will have changed flow characteristics of the engine. Have fun
i did the stupid thing to use an scooter tuned pipe on my motorized bicycle god.... the sound looks awesome and i think it goes 30% stronger than before... but now i do need a proper carb and reed valves to make this uses all this power due.... since thats bigger than these exhausts.... i think the engine doenst fill right lmao
heres best tip ever.. go with a lower back sproket.. muffler carb none of that matters its all how short youre chain is.. i listend to these dumb people a hole year.. untell i found that on my own my 2stroke dose 45mph with a 36 tooth sproket..a little slower on start but lets race any ways
your tests results are subjective, and in my opinion, a little skew. comparing a stock muffler to the flex fit poopoo, I lost 3mph with the flexi and 1500 rpm on top, due to the flex pipes inner diam was actually smaller than the stock pipe. length also is not good for top end, as a longer pipe is almost always more restrictive than a short one. the performance increase was slight in the low to mid, producing more torque than stock, but beyond 3400 rpm, it fell off noticeably.
scavenging is real atvantage of a tuned expansion chamber. the pulse of each firing and exh. event lends itself to pulling the fresh charge of pure air fuel into the cyl. . the pressure wave which otherwise does not get taken atvantage is used and in effevt acts like a turbo or supercharger increasing the volume of firing charge per event, meaning bigger bang.all chambers have different characteristics.
Did you bother to rejet at all? Heard a lot of 4 stroking. Mz65 pipe is THE BEST BOLT ON PIPE. Without a doubt. Amd with proper tuning no you will not burn your leg. The absolute best is a modified 60-85cc dirt bike pipe
I took the baffle cap off of my stock exhaust and it's four stroking above 24mph. I don't want to try exhaust porting yet but I heard that running it leaner could help. Is this true? I'm getting the f2 thruster anyway but it still might four stroke. So do you have any tips to get rid of four stroking? Thanks.
I was kinda hoping to see a demo of each muffler's sound, as well. Not just the volume ratings
I dreamed I was a muffler. I woke up EXHAUSTED! ;) ;)

First and foremost you’ve got to remember there’s a lot of beginners who don’t know that much about these engines and they will fall into temptation and buy one of these pipes. I personally have tested a f2 pipe and it doesn’t compare to a slightly modified stock exhaust. Do your research and get what’s best. None of these pipes are going to be good
They may look and sound cool but are they worth the bang for your buck
@@motorizedandrew3942 What did you do to your stock exhaust pipe to make it better than the F2? I sawed off most of the stinger from the cap and it didn't seem to do anything. The acceleration feels really slow. If I take the cap off the bike comes alive and I can feel the acceleration, but it's so damn loud it's not even fun to ride on the road.
@@mad_scientist5597 take a soda can and some steel wool. Remove said cap and replace with soda can and steel wool. Btw just remember to drill some SMALL holes. Nothing too big but you want lots of holes. The exhaust will try to push the can off so use a hose clamp and make sure flow is good
@@motorizedandrew3942 What's the difference between doing this, and just cutting the stinger and drilling holes in the cap itself? And what's the steel wool for? I don't have a lot of experience with this stuff so I wouldn't know
@@mad_scientist5597 the cap technique is really iffy. Some engines will benefit and some won’t. Just removing the chamber inside or what you call the stinger isn’t enough. Drilling holes in the cap also makes it sound like trash. I have never liked the sound the 2 strokes make with the cap holes and chamber removal aka sleeper mod.
The steel wool is to help with sound detonation. Although be careful because steel wool can ignite. Fortunately steel wool won’t really burn it will just create a bunch of little small sparks and then turn into nothing. If your engine gets loud then you know what the issue is.
On most lawn equipment 2 stroke engines they have a little screen in the exhaust called a spark arrestor. It’s job is to make sure spark don’t fly out. The real truth is it’s mostly an epa thing. Spark arrestors do have a place tho. Generally a well tuned engine isn’t going to create sparks. I’m a 2 stroke since the exhaust hangs open in the upstroke it will let some unburied fuel mix out. Now if your not well tuned and you have pre detonation going on it will create sparks going out the exhaust.
To sum it up… you should be fine with steel wool as long as you don’t have pinging or pre detonation or excessive 4 stroking. You will have to tune your carb because you will have changed flow characteristics of the engine.
Have fun
i did the stupid thing to use an scooter tuned pipe on my motorized bicycle
god.... the sound looks awesome and i think it goes 30% stronger than before... but now i do need a proper carb and reed valves to make this uses all this power due.... since thats bigger than these exhausts.... i think the engine doenst fill right lmao
The worst part about aftermarket mufflers is finding the control arm bearing. Once you figure that out it's all uphill from there. 😆
Please look up cosine error. You are not using the speed gun correctly. Otherwise this is really good information.
My bike runs 37 mph. All stock
mine dose 30 pulling 450 pounds
Mine did 32 during the beginning of the break in period. I haven’t tested the current top speed yet.
heres best tip ever.. go with a lower back sproket.. muffler carb none of that matters its all how short youre chain is.. i listend to these dumb people a hole year.. untell i found that on my own my 2stroke dose 45mph with a 36 tooth sproket..a little slower on start but lets race any ways
@@spunn_co very true. I got rid of my chain tensioner and what a difference. I had to cut the chain and ad a link to the bike chain but it's worth it
@@richardprevost8187 does it really work how much chain need to be tight
your tests results are subjective, and in my opinion, a little skew. comparing a stock muffler to the flex fit poopoo, I lost 3mph with the flexi and 1500 rpm on top, due to the flex pipes inner diam was actually smaller than the stock pipe. length also is not good for top end, as a longer pipe is almost always more restrictive than a short one. the performance increase was slight in the low to mid, producing more torque than stock, but beyond 3400 rpm, it fell off noticeably.
what is this?
ehhhh idk abt this also it matters what engine you have as well keep that in mind
scavenging is real atvantage of a tuned expansion chamber. the pulse of each firing and exh. event lends itself to pulling the fresh charge of pure air fuel into the cyl. . the pressure wave which otherwise does not get taken atvantage is used and in effevt acts like a turbo or supercharger increasing the volume of firing charge per event, meaning bigger bang.all chambers have different characteristics.
I got the f2 thruster in mine also called the thrust racing muffler 😍😋! Check mine out plz!
Did you bother to rejet at all? Heard a lot of 4 stroking. Mz65 pipe is THE BEST BOLT ON PIPE. Without a doubt. Amd with proper tuning no you will not burn your leg. The absolute best is a modified 60-85cc dirt bike pipe
I took the baffle cap off of my stock exhaust and it's four stroking above 24mph. I don't want to try exhaust porting yet but I heard that running it leaner could help. Is this true? I'm getting the f2 thruster anyway but it still might four stroke. So do you have any tips to get rid of four stroking? Thanks.
Hello, please add Russian subtitles) we just don't have such videos)
I put a f2 on my bike
at 2:00 we wanted to hear the exhaust
