Do a test with the stock pipe and remove the end cap vs the mz65 clone. The results will be much much closer . Also stock pipe with stock jetting is rich so there is a power loss there compared to the clone.

@@LAHover personally simply removing the baffle cap of a stock exhaust will never make as much power increase as a ktm65 or ktm65sx pipe. It just simply isnt designed for resonate flow. To each is own though. Personally i run a ktm 65sx on a ZL40MM crank with a Falcon 911 cylinder, ktm pipe is MUCH better than the stock, even baffle cap removed, also better than even gutted. Just personal preference tho ig
@@LAHover for the record bro i am also referencing a real ktm65 basic dirt bike pipe rather than the clone WC80 styles so chances are your results are exactly like mine haha, to be fair its all in the name. A clone isnt going to do as well as a standard db pipe but its certainly better than nothing personally (for the record the first time i ever hit 50 mph was with a gutted stock exhaust, didnt do it very fast but could wind up like hell lol)
Any chance we could run a test with a silencer that will get the dbs wound out down below 95db which is about bylaw and neighbor pi$$ing off volume. Where I live there is absolutely no way I can run the better pipe (probably even the stock)unsilenced or I'll have the cops on my doorstep every day! Thanks.
Myself, I appreciate the excellent play by play on the voice over, excellent job man. And do agree on selling your own performance motors because you've tested everything very meticulously, so out of the gate you are already a trusted by many of us.
with a 2-stroke swapping out a straight pipe with an expansion chamber is like putting a turbo on a 4 stroke. 30+ years ago an old timer/ old school racer said it best. Putting an expansion chamber pipe on a 2-stroke is a sonic supercharger, as the pipe gets bigger it creates a negative pressure between the exhaust port and sound wave pulling out the burnt gasses and even some fresh air/fuel charge, as the pipe decrease in size it pishes the fresh charge back into the cylinder increasing the pressure at time of port closure acting like a supercharger/turbo. My person ride was a TRX250R with a grand national MX porting to boost midrange power, pipe/chamber was an LRD adjustable/tunable chamber where I could lengthen or shorten where the reverse cone started. With the MX porting and the pipe set in the middle my little 250 would DESTROY 350 Banshee and quadzilla 500 on the MX track. For bottom end punch lengthen the chamber, top end shorten the chamber. Class dismissed LOL
I just can't express how much I like these videos. So helpful and joyful sounding! Many thanks. Also. My 49mm iron sleeve arrived today so opening it up shortly. Gonna upload something
Love this test! The mz65 clone pipe all FB group guys swore did nothing for my bike's performance and any gains were in my head finally gets some recognition.thank you for taking the time to do this video
I got one of them pipes , it did help in getting to top ram a little quicker. Can't say it actually run better with the exception of when it was singing. I expected more. After taking a good look at the pipe with seem to be made out of cheap electrical conduit pipe rather than exhaust pipe. The pipe was shoved in like 6 inches on the one side and 4 or 5 inches on the other side. I cut the welds pulled the pipes out and rewelded them. Actually works better now. Not sure if the volumemetric is right for this motor but helps Like you said in one earlier video relating to bang for the buck keep em cheep a little elbow work and fun
When you're ready to build your own pipe leave one variable, that being a stinger that can slide into the expansion chamber and back being clamped at any given point, thus creating a variable back pressure which will help with the scavenging effect. I once did r&d for Kawasaki and that trick saved tons of time when testing expansion theories on dyno tuned pipes
"Welcome back motorized bicycle enthusiasts!" And if you're a sad angry old man who knows none of this is "rocket science" because it's all "simple stuff" then you should go spend your time making grumpy old man videos that no one will watch. Meanwhile, the rest of us enthusiasts will enjoy something worth watching.
Hey now ! Leave us grumpy old farts alone ! lol . Just got into the motorized bike life style a year and a half ago and loving it. I listen and watch you young wipper snapers here and you guys showed me alot ! thank you. Been riding mtrcycles since 1973 and I'm having more fun now than then . Already starting on my 4th build . At 61 I'm looking for comfort and pulling power.But this next build is going to be wilded ! I may post my rides on you tube but I'm no content creator...enjoy !
I've had other engines, but this one with the G4 cylinder, real NT Speed carb and stock pipe, with a rubber ring in the carb, was the best running engine out of the box. It idled and I couldn't see any need for a jet change. A good bit of torque for as quiet as the stock muffler was.
Bike engines got the new bushings in for the phantom 85 last week, should be shipping units in the next 1-7 days. Pretty excited to have a running bike again.
When I put the faux MZ65 pipe on my Zeda80, I could hear, and feel the difference from the stock pipe, and with a 41T sprocket it pulls like a tractor! It IS like night and day, and it just seems to run better and better every time I ride it...
@@Bobs-yer-uncle all I did was swap the stock #70 mainjet for a #66 (for that bike), and moved the needle down one space. If it's a new engine it will 4 stroke during break-in, but that should go away after time. Like I said before, mine runs better every time I ride it...
Thanks for the video! Been planning my own Expansion exhaust, port mapped and everything, just need to get ahold of some cone sections. The clones had me weary, but this video has been insightful
ive made two expansion chambers for these bikes, I think the basic things to note are that the longer the header pipe is, the lower rpm range it will help. If its too short, your bike might not even get into the rpm range where the expansion chamber is useable. The length of the diffuser come also affects this. The angle of the diffuser cone affects how wide of an rpm band it affects. Lower angle = more range less peak power. I think since these bikes don’t have gears, a long and low angle diffuser cone is the way to go. As for where the expansion chamber kicks in on the rpm band, make sure your back sprocket is big enough to allow you to reach these higher rpms if you have a shorter header. Expansion chamber body diameter should be about 2.5 time header diameter/ exhaust port diameter. the stinger diameter should be about 65% the header diameter. These are the approximate figures I used (going off some other guy who did something similar) Theres a lot more I could go into regarding expansion chamber angles, diameters, and lengths but that’s the basics I’d say. If you want to have one of my expansion chambers I’ll send pictures and sell it to you if you’re interested.
Great video and information as always.... After this series, can you do a video or videos of adding an aluminum performance head along with it's pro's and cons..!! That would be awesome if you could..!!!!
Can't wait until you get the phantom up and running again, I got in contact with bicycle engines and have parts on the way. Still haven't run mine yet... I may do what you did to try it out, put it on a bike as a swap.
I use a 40t sprocket right in the middle of the 36t and 44t and I live in a hilly area of Florida and it does great, best of both worlds gives you decent speed while being able to get up even 30° inclines with minimal issue
I got my bike running so amazingly good. I didn't have a jet kit, and my bike was always 4 stroking making me think it was really broken. It was 4 stroking bad. What I did was I had a spare YD 100 carb from a friend, and I took the jet out of the regular carb and put it. In the yd100 carb since it had a bigger intake barrel, and moved the pin all the way up and now it gained 5 mph and the pull with a high compression head with an expation chamber is freaking insane. It pulls from stops no problem and mid-top end makes me fall back on my seat. It's pretty sweet. Top speed is only 29 mph though. It 4 strokes a tiny bit at full throttle at 29 mph. I ordered. A jet kit so hopefully. If I jet down 1 size it will help even more.
@@LAHover today i jetted down to like a 65, and i got to 35 mph on my first pull, it was a short pull and i bet it goes faster! this bike is crazy dude, all because of your videos i learn so much!
Great vid,and info LA.Thnx.When I just changed from the stock muffler,(modified as you've shown too)to the Poo-Poo,my bike's torque jumped to where it wanted to wheelie.When you get the ports cleared,will you please compare the P-P to the MZ?Thnx again.
It really isnt suprising that the top speed is not affected by the pipe alone. The exhaust is just one piece of a few that need to be upgraded in order to improve the rpms, power and speed.
That is reason i was talking to about if u aint got higher gear like a 48 tooth or 56 tooth now 44 tooth is a good gear but where i live at the bottom of the mts at is in the foothills they are alot of steep hills here where i live here in wikes County u do make good videos man i glad u got a nother motor u don't see many good companies around that stand behind there that for sure so becareful out on the rd
Most people don't realize that top speed is going to be limited to the rear gear for the most part with in a couple of mph .. there are other veriables that come into play that will limit top speed.
Awsome videos and great seires. I 100% agree with your therioes of limitations vrs. Longevity. I worked with a couple of the old blocks "LD80" they didnt even make it past breakin with pre-checks, torquing etc. The newer blick design I aquired and just finished prepping, and mounting and WOW what an improvement right off the bat. Much less vibrations... big plus, smoother even on very first start up and over all a better block which is stampped "7MN" on the jug as opposed to "LD80". Is it possible the new block breaths so much better that it could actually be running a tad lean? Even though the same carb setting worked great on the older design blocks. Too early to plug check. Just wondering? Because she loves a tad too much choke on warm-up. (Last moter dud that when I set her a tad too lean) Just asking, Being extra cautious with this one.
Great Video. I have build one kit in the past and it was made by anbull. Great kit. I am looking at building another one and I was wondering if a chinadoll would fit on a granite peak roadmaster from walmart without any major modifications. I want a bike that is safe to ride and was wondering if I shoudld go with the roadmaster or a huffy cranbrook. Thanks.
I have built on and enjoyed both bikes. I recommend the Granite Peak over the huffy so you don't have to deal with the coaster brake hub and rear wheel bearings. It is a bit of a tight fit around the carburetor, but on most builds I was able to just remove the air box and ziptie the air filter and filter cage to the carb... or use an off sett intake if you can find one this is not junk...
I don’t think my bike has a top speed keep the throttle open long enough u keep slowly accelerating I took my bike down a hill and made it hit 100kmph it was terrifying and so fun
I have a wildcat pk80 on a bike with 700c wheels and a 36 tooth sprocket with an mz clone, I've only managed a top speed of 37mph and I'm pretty disappointed. I'm still playing with the jetting and I feel like I'm getting closer to the 40 mph mark. But sometimes I feel like I'm chasing my tail...
Anything 35mph+ is a respectable speed IMO. The gear ratio of a 700c with a 36t sprocket should hit 40mph+ with a 200lb rider and the right jetting. BUT, these speeds are pushing well past the safe limits of most bicycles so please be carful!
@@LAHover I think I'm still too heavy, I ordered the wrong set of jets, so the smallest one I have is either a 70 or back to the mystery jet that came stock.
As long as you put in a bigger fuel jet to increase the fuel whn you put a tuned pipe/exhaust on it will be fine and run abit more 2stoke oil or better oil will help with it lasting longer 👍👍👍👍👍👌👌💯💯💯💯
@@LAHover I got a sunlight monarch fork dbl spring for my beach crusier w/anbull 80. It's a tank ! lol . I trust it very much. Say hello to Henry for me : )
With stock port timing I don't think you will see much of a performance difference. From what I understand (could be wrong), Reed valve set ups work great once you start increasing intake duration... among other things. I'll do my best to test a reed valve early in the series for you guys.
@@paullehman8652 I'll tell you what ,I did the same thing you are wanting to do with the bolt on upgrades. But my bike ran way worse. I had bought a CDH Power Dio Reed, I also ordered a windowed piston, which I had watched video after video, to try and make sure I got the correct size and shape window in the piston right, lol ok stuff finally comes in I put it all on the bike....... The dam thing wouldn't start. So 2 more hrs later finally get it to start, but now had to stay on full choke or would die. But it lost big power gained no power. Now this was on an 80cc motor that I had and had stock carb stock exhaust and the cylinder was not designed to accommodate a Reed setup, as far as transfer port, port timing etc. But it didn't cost a bunch money , I may have had thirty bucks in it lol so if you want to do you own testing, this isn't going to financially cripple you or anything lol. But for me it was a waste of money Hope this helps , good luck with yours. And if you have better or different outcome let me know what was different
Not bad. I get 37 mph on a 20” rim with a 36 tooth. And can climb hills without pedal assist. It is all balance and believe me when I say hills. I live in a area where the elevation is 3,700 above sea level. But just want to have the engine to stop vibrating at top speed. Wish I could hit 45 mph.
If your looking for a welder, the harbor frieght 110 flux core will weld a banana pipe and its cheap. Highly recommend a auto darken hood. I wonder how a banana pipe with the exhaust end opened up would fare against the exhaust you tested. I found more low end torque to the point i no longer chug from a standstill, cant comment on top end Also recommend more armor. Less skin to get rashed.
Just remember the old saying cry once buy once. If you can afford a bettter welder, i highly recommend it. Manipulating metal is a handy ability. The 110 kit from harbor frieght comes with the bare minimum you need to weld, i forgot a decent wire brush with the auto darkening hood recommendation
Still alive, and running great! :) got the Path Dragon locked up under a tarp on stand by, just incase I need a reliable back-up bike because I broke everything else lol ;)
Gas frames bikes are nice but IMO not worth the $$$. I have never tried the hyper, but I like the back slanted seat tube. That might come in handy if you start testing bigger carbs and filters.
The wc80 is still not worth 3-400$ imo tho, even with added acceleration, personally a gutted stock will do the same acceleration. Hands down though very in depth and nice example of the two between themselves
Might be thinking of a different pipe, or the price may have been inflated when you saw them. ATM The Deluxe/WC80 (same pipe) are about 80-100. Thanks for the love :)
Hardware570 said the MZ65 clone isn't nearly as good as an actual MZ65 because the clone has a small single size diameter restrictive header....The real MZ65 has a header pipe that gradually increases in size/diameter before it gets to the belly that apparently allows for better back flow into the engine. I'm by far no expert but read the long straight cone style expansion pipes often seen on mopeds are made to mainly increase top speed/end power since they're most often rode wide open throttle cruising down the road. The curved type like the MZ65 on dirt bikes are made/curved for ground clearance but also to provide improved power through the whole throttle range, not just top speed. I just noticed something else bogus about BikeBerry is they show a picture of a real MZ65 pipe for sale $70 but then send you the clone.
I still tend to go through bikes faster than I do engines. I still have to shoot for overall reliability before trying to make a monster performance machine. Poor quality replacement wheels have been my biggest bugbear lately
Can you do a review of an actual mz65 clone from California Motorbikes or elsewhere? It's completely different from the Amazon and Bike berry fake one. No need to fabricate one... Although we all want that video anyway hahaha
Part three in this play-list compares the Deluxe pipe (WC80) to the one here in Part Two :). Hope it helps you decide. Spoiler, acceleration is down but top speed is up, and the welds are... baaaaaddd :/
It's a long road with many things to test. The MZ65 is relatively cheap and has not had a solid head to head test on TH-cam as far as I can tell. We now have real results that any builder can see to make their own decision. We will be testing it against other pipes as well throughout the series. Enjoy :)
Nothing wrong with that at all. As a matter of fact, I have been riding the heck out of the stock 49cc 2 stroke bike lol... Not sure why, but it's just fun.
Do a test with the stock pipe and remove the end cap vs the mz65 clone. The results will be much much closer . Also stock pipe with stock jetting is rich so there is a power loss there compared to the clone.
Good call
kjsmolik brings up a good point. If the MZ65 Clone's expansion chamber is not effecting performance, than there is a good chance that a cap removal on the stock exhaust should give similar results, assuming you live in an area where you can get away with the noise ofc. :)
@@LAHover personally simply removing the baffle cap of a stock exhaust will never make as much power increase as a ktm65 or ktm65sx pipe. It just simply isnt designed for resonate flow. To each is own though. Personally i run a ktm 65sx on a ZL40MM crank with a Falcon 911 cylinder, ktm pipe is MUCH better than the stock, even baffle cap removed, also better than even gutted.

I have a wildcat pk80 on a bike with 700c wheels and a 36 tooth sprocket with an mz clone, I've only managed a top speed of 37mph and I'm pretty disappointed. I'm still playing with the jetting and I feel like I'm getting closer to the 40 mph mark. But sometimes I feel like I'm chasing my tail...
Anything 35mph+ is a respectable speed IMO.
The gear ratio of a 700c with a 36t sprocket should hit 40mph+ with a 200lb rider and the right jetting.
BUT, these speeds are pushing well past the safe limits of most bicycles so please be carful!
@@LAHover I think I'm still too heavy, I ordered the wrong set of jets, so the smallest one I have is either a 70 or back to the mystery jet that came stock.
Heavy with the jetting, not heavy in general lol. I weigh like 150 so I'm definitely not getting all she has
As long as you put in a bigger fuel jet to increase the fuel whn you put a tuned pipe/exhaust on it will be fine and run abit more 2stoke oil or better oil will help with it lasting longer 👍👍👍👍👍👌👌💯💯💯💯
How is that triple tree fork working out for you? I heard they like to fold up and are cheaply built.
Feels like junk, I don't trust it, but so far no problems. Will be replacing it with some good mountain bike forks.
@@LAHover I got a sunlight monarch fork dbl spring for my beach crusier w/anbull 80. It's a tank ! lol . I trust it very much. Say hello to Henry for me : )
Hello hover could you send a link to your audits I have one I just finished I'd like to share
Did u get your phantom going
New one on the way, not arrived yet.
I’m putting on a g2 reed valve with my stock carb and windowed piston will it make my bike faster or hurt it
With stock port timing I don't think you will see much of a performance difference. From what I understand (could be wrong), Reed valve set ups work great once you start increasing intake duration... among other things. I'll do my best to test a reed valve early in the series for you guys.
@@LAHover oh so do you think I should just not do it and also I would like to see that in a video
@@paullehman8652 upgrading the exhaust is your best proven bet, as far as bolt on power.
@@kennethferguson9828 I have an upgraded exhaust
@@paullehman8652 I'll tell you what ,I did the same thing you are wanting to do with the bolt on upgrades. But my bike ran way worse. I had bought a CDH Power Dio Reed, I also ordered a windowed piston, which I had watched video after video, to try and make sure I got the correct size and shape window in the piston right, lol ok stuff finally comes in I put it all on the bike....... The dam thing wouldn't start. So 2 more hrs later finally get it to start, but now had to stay on full choke or would die. But it lost big power gained no power. Now this was on an 80cc motor that I had and had stock carb stock exhaust and the cylinder was not designed to accommodate a Reed setup, as far as transfer port, port timing etc.
But it didn't cost a bunch money , I may have had thirty bucks in it lol so if you want to do you own testing, this isn't going to financially cripple you or anything lol. But for me it was a waste of money
Hope this helps , good luck with yours. And if you have better or different outcome let me know what was different
Not bad. I get 37 mph on a 20” rim with a 36 tooth. And can climb hills without pedal assist. It is all balance and believe me when I say hills. I live in a area where the elevation is 3,700 above sea level. But just want to have the engine to stop vibrating at top speed. Wish I could hit 45 mph.
If your looking for a welder, the harbor frieght 110 flux core will weld a banana pipe and its cheap. Highly recommend a auto darken hood.
I wonder how a banana pipe with the exhaust end opened up would fare against the exhaust you tested. I found more low end torque to the point i no longer chug from a standstill, cant comment on top end
Also recommend more armor. Less skin to get rashed.
Thank you for this information!
Just remember the old saying cry once buy once. If you can afford a bettter welder, i highly recommend it. Manipulating metal is a handy ability.
The 110 kit from harbor frieght comes with the bare minimum you need to weld, i forgot a decent wire brush with the auto darkening hood recommendation
What happened to your dragon bike
Still alive, and running great! :) got the Path Dragon locked up under a tarp on stand by, just incase I need a reliable back-up bike because I broke everything else lol ;)
I know that this doesn't go with the video but have you ever changed the jackshaft and bearings on a phatmoto
No sorry, never had one to work on. I do love the look of the all terrain models. Might get one some day.
Oh what bike frame do you think is the best. Huffy cranbrook or the hyper beach cruiser. Or is the build in gas tank frame better?
Gas frames bikes are nice but IMO not worth the $$$. I have never tried the hyper, but I like the back slanted seat tube. That might come in handy if you start testing bigger carbs and filters.
@@LAHover I have the hyper now and I use to have the huffy.
how long could i go full throttle for without damaging it?
Where did you obtain the degree wheel? 🧑🔧
Put it on a huffy Cranbrook and do a mpg test
Will do a MPG for you guys along the way :) not sure what bike it will be on, but both will have 26" wheels and probably a 36T sprocket.
Did that vehicle that passed you while there was oncoming traffict bother you stall?
Yes, but not much I can do about it... unless I see it parked somewhere ;)
The wc80 is still not worth 3-400$ imo tho, even with added acceleration, personally a gutted stock will do the same acceleration. Hands down though very in depth and nice example of the two between themselves
Might be thinking of a different pipe, or the price may have been inflated when you saw them. ATM The Deluxe/WC80 (same pipe) are about 80-100.
Thanks for the love :)
Can you compare the clone mz65 Vs real Vs wc80?
Yup! already planed out :)
Hardware570 said the MZ65 clone isn't nearly as good as an actual MZ65 because the clone has a small single size diameter restrictive header....The real MZ65 has a header pipe that gradually increases in size/diameter before it gets to the belly that apparently allows for better back flow into the engine.
I'm by far no expert but read the long straight cone style expansion pipes often seen on mopeds are made to mainly increase top speed/end power since they're most often rode wide open throttle cruising down the road. The curved type like the MZ65 on dirt bikes are made/curved for ground clearance but also to provide improved power through the whole throttle range, not just top speed. I just noticed something else bogus about BikeBerry is they show a picture of a real MZ65 pipe for sale $70 but then send you the clone.
I still tend to go through bikes faster than I do engines. I still have to shoot for overall reliability before trying to make a monster performance machine. Poor quality replacement wheels have been my biggest bugbear lately
Have tou considered upgrading to moped wheels?
@@DragondekaTS020 its a $$$ thing right now. If I can't fix it for free it stays broken
Same... More motors now than bikes lol...
It's a dual spark plug cylinder
The rob Dahm of motorized bikes
Can you do a review of an actual mz65 clone from California Motorbikes or elsewhere? It's completely different from the Amazon and Bike berry fake one. No need to fabricate one... Although we all want that video anyway hahaha
Part three in this play-list compares the Deluxe pipe (WC80) to the one here in Part Two :). Hope it helps you decide.
Spoiler, acceleration is down but top speed is up, and the welds are... baaaaaddd :/
Hi
Why the mz65 clone?
It's a long road with many things to test. The MZ65 is relatively cheap and has not had a solid head to head test on TH-cam as far as I can tell.
We now have real results that any builder can see to make their own decision.
We will be testing it against other pipes as well throughout the series. Enjoy :)
@@LAHover ahh ok
I no the trek not hard to do 42 on this motors
LA nice at he’s work ❤
It is all about the pipe u get the real mz65 pipe u will tell the difference
We just got a Real MZ that we will be testing soon :)
I leave my bike stock except for the compression head because it's my every day go getter
Nothing wrong with that at all. As a matter of fact, I have been riding the heck out of the stock 49cc 2 stroke bike lol... Not sure why, but it's just fun.
I've need to put 49cc on mine to dequincy cops r bad
