Yea pipe does the hard work any 2 stroke will run like crap if it’s huffing and re cycling fuel charge

Jorell Dye thanks you the man for that info brother

thanks bro

Fat groove down and up through the inlarged intakeport level with the other transfers.thats the only reason for a change to reeds, . That reed doesn't flow.

Alasdair McC how do you port the transfers

DONT KNIFE EDGE air likes to flow around smooth round objects not sharp edges, I did a test with a yz70 and picked up almost .5 hp with the same timing same port volume only difference between the cylinders was the shape of the transfer

Idk why people don't understand that knife edging is a no no.

@@kenturmon3660 What exactly is knife edging? I'm not familiar with the term. Is it to describe a sharp finish on the intake/ exhaust ports?

Like any engine ever, you think these puny exhaust are good for any motor.. pfft that's why they call em upgrades.

@@dangerousdoggo5465 I still run the stock exhaust on mine, so I would agree they run forever, currently at 7,000 miles on the motor and still ran with the exhaust with the baffle inside.

@@dangerousdoggo5465 that sounds like alot of upgrades, I'm going to port the intake and exhaust, I already helicoil the bolts holes in the motor reduced the vibrations and helped em never strip a bolts

@@eduardodiaz5762 your not at 7000 miles

@@mechanicalking your right I'm at 7,710 miles so far.

I had a 66cc that was ported and had a f2 thruster (basically straight pipe) With a stock nt carb and it went 47mph with a 44t on 26” wheels which that’s means it should have been turning 11k

Im thinking about porting mine as well. As I've seen lot videos on here where people people seem to improve there engines output , u get arround too porting yours the carb intake and the exhaust end plus exhaust ,as be interested in the difference standard and after the porting .

Michael Husband they are brand new. Check the other video. They close perfectly

AuMechanic we do our testing as if someone that has no idea and buys performance parts thinking they can just bolt them on and go. 90% of the time this is the case. The other 10% aren’t here on KZfaq looking for how to videos

ya they have to, its a stock carb being tested in a consistent testing environment, with a magneto spark i.e. what alot of airplanes use even to this day. It appears you havent even touched one of these motors , otherwise you wouldnt be trying to lecture those kids the way you are, troll.

Loren Keith and these motors are very touchy. One day it can make 1/2 hp more then other days. So back to back testing is best. Atleast on these engines

Yes I can see the logic of that, most would just buy them and bolt on hoping for results.

also it takes the third transfer port to make any kind of real hp change. But still if reeds dont shut it not going to do anything but make it worse because the fuel has trouble getting past a couple of reeds vibrating all over the place. also did it blow a crank seal thats the first place your loss of power will go. you've stopped all pressure going out the intake so it goes out least resistance which sometimes can be crank seal. l plate my crank seals in so they dont blow.

I have a triple 40,and just bought a dang RSE reed.I didn't port.I Did match gaskets to them,and micro beveled the inside edges.I'm running 44t on a Hub-adapter and like the torque and milage I'm getting.Only 'mod' was the long tube up into the muffler,and I cut 1-1/2" off,then stuffed 1/2 a choreboy in it.I get about 120mpg.

BryDuhBikeGuy what kind of top speed are you getting?

32 is as fast as I've tried and the throttle cable wasn't pulled all the way.I cruise @18- 19 so it stays legal.(Motor-assisted instead of 30mph Moped class)Happy Trails.

Oops.That's on a 26" Mt.Bike weighs about 50lb with rack etc.I'm 185

Just did a 35mph run,(outside of town and back road)and it hummed.I could do more,but it's a Bike.Sheesh.LoL.Mongoose front suspension,but still..not going more.Happy trails .

I wanna see that third transfer

Zoreldan it would defeat the purpose

Boost bottles do very little if not work at all, zeda motorsports would agree.

Deimos Phob maybe cause the way the carb works ? Ram air night not be good for these engines and carb

Ram air works really well on carburated cars, idk why it wouldn't work well on carburated mopeds.

@@deimosphob ram air doesn't work on carburetted cars

Yes, it does Gordon, on old cars people always put air-rams and stuff on their cars, and they always had higher performance with air rams despite them all being carburated. Hell, you can even turbocharge carburetted cars, as even with a cheap amazon turbo kit you can expect an easy 2-300 horsepower gain on a small block cast iron chevy, hotrod network did a segment on it, and it was carburated, actually most turbocharged/ram air muscle-cars are carburated, so the whole idea that "ram air doesn't work on cars" is bullshit, it works, and it makes power.

BBR tuning for life

It'll never got power band without an expansion chamber pipe. These upgrades are useless without that 1 all important part. 2 strokes rely heavily on exhaust tuning

Plus i windowed my piston

@@hermann6674 Planes trains and automobiles. We were robbed!!!. I have steve martins face on.... "Do you think"?

Daniel DeNapoli it was hot already

Isaiah Rolon I think it’s funny you don’t understand this video. Bolting a reed on a motor that isn’t ported for it doesn’t work, as this video shows.

I use the rse reed on a completely stock set up. a lot needs done to get fair results in power. the first thing you should do is open the intake port up, so the Reed can open properly. definitely chamfer the exhaust port for two reasons. 1. so the rings slide smoothly over the port. 2. it creates a .8mm increase in the open duration of the port. you can benefit from making the exhaust port wider too but it's not a necessity like the foremost mentioned. ideally any stock kit you have should be port matched with the manifolds. you wouldn't want to drink from a container that blocks most of the fluids would you? nor shit out a turd through two buttholes, one big and the next small....you need to wipe till it hurts! anyways, another important thing that must be done, the stock exhaust sucks the life out of a reed my honest opinion is don't use it. although two things can be done to make it work and work well enough to power up inclines with out much of a running start. 1. take the 10mm bolt out of the baffling cap and pull the long pipe out from the muffler. you'll see that pipe is attached to the cap. cut that thing off as close as you can to the cap. 2. drill open the left over pipe on the baffling cap till the metal is thin and bendable. when that's done you, gave yourself a little bit of exhaust tune ability with a crude "stinger" the more you have the hotter the pipe, the less you have the cooler the pipe. cold pipes can push more, hot pipes can Excell more. something else can be done but it's not a gonna hurt much if it's left alone. inside the muffler you'll see some tin discs with holes in them and it's connected to the screw hole to bolt the cap back on. along the walls you will find shotty weld beads that hold that garbage in place. if you got 12v and 10 amps you can melt those things off with long pieces of 14g copper wire and a junk screw driver. if you take it out drill two holes at the end of the muffler and baffling cap one across from the other to screw the cap back on. now regardless of what pipe you use you will never see nothing past 40mph with a 36, 40, 44, tooth gear. you can try a 32 but it will take you miles to get 45mph with just a piston ported rse reed. you got your piston ported out and it's getting all the intake it needs, yep. only problem now is the exhaust it still on piston port timing and the top end has lost power. that's why a boost port should be cut in. I'm not talking about a hole trench to the case. cutting down to the case only hurts bottom end power because doing that increases volume in the crankcase. just make a half bowl shape above the intake UP TO the top of the transfer window. the boost port isn't important if you don't wanna speed. with this set up using nothing but modified stock parts you should see over 4 horses, with a boost port the apex should reach near 10k and pushing 5 horse. oh, I forgot about the carburetor. take the air box off and leave it off. get the plastic thing that looks like a bullseye and cut all the plastic out of the center leaving nothing left but the outer ring and two screw holes. that plastic bullseye screws up the air flow. now look at the choke you see the lip thats protruding out of the venturi tube. that lip is intended only to ensure the choke chokes. well smooth that lip down so air can pass undisturbed and bend the choke in a bit. by doing that you get better idle and smoother throttle control and makes the bike that much more tunable.

Casey how do you do a boost port

Ther are plenty engines with the reed valies on the cilinder

re-read my comment.. Didn't say there wasn't

Dfe st rqdsrf

nope , they won't show the right way to port the engine or tune the carb for the reed valve , but they will show the wrong way to bolt on parts and expect your stock carb and exhaust to keep up with them

Bunch or A holes for ignoring your comment, that's why i didn't buy anything from these snubs, they don't deserve my money, and also my friends when they ask me I tell them first thing not to buy from these guys.

@@johndawd4616 exactly, Zeda used to be top dogs, the best of the best when they first came out and had a name to gain, now they have gotten greedy and are absolute trash. They will take your money and half the time not even send the right parts. I literally trust gasbike.net more than i trust these guys. Its sad honestly, the same people and websites Zeda slams and talks shit about, are better than Zeda to begin with, how ironic.

@@johndawd4616 shit, Amazon is better than Zeda now, bikeberry another website they slam is 100 times better than them aswell, actually have a motor from them with no issues. Ofcourse always check your motors to make sure everything is correct regardless who you get it from, but Zeda, i doubt you could even buy a motor from between them never being in stock, retarded overpriced, or if they even send it to you at all.

It's that reed he's using it's just got one flap in it and they restrict the air really bad if he put a bigger reed on it the power would've came right back...I just did it to mine

When you find out, let me know so I could go pick up the expensive part they never sent me!

Yep 5 bucks for using a dyno is a lol cause ya dreaming if anyone would do it for 5 bucks maybe in your mind not the real world

Robert Rodgers don’t buy bikeberry

the jets suck! Go Cowboys!

Loren Keith lol man I get very limited time to even mess with you tube. So I try to post when I can brother

Okay these need adjustments done. The motor is going to do its best based on atmosphere conditions regardless. So here this man has a controlled setting. Testing add on parts is good to see where a motor is at for power. This man has a DYNO. I dont have the luxury of a dyno YET....You imply 24 hour cool down period between testing? Maybe the next guy will say only 20 hours. How is letting the motor cool and sit for 24 hours going to help it before the next test? It dont. Assuming it is in good operating condition, sealed tight, no leaks. Does your bike run higher after it sits for a day, then higher the next 24 and so on? I bet no. Get off your high horse and dont knock the man for helping. We are all a searcher for more speed. Most people dont know that these parts need a certain amount modding to get the ideal result. Without a DYNO you have nothing to go by but, sounds, feelings, vibrations and what you had for breakfast. I run the CDH 32-40mm reed (not the best ok but it works) but I had to mill my windowed piston and add ramps 30 degrees by width of the transfers x .25" deep including a multiple radius slope for duration transition based on the height I set my jug. If your transfers are not opening all the way you got a problem. I can break 28 mph on a single speed with a 56 tooth with huge off the line torque. I was told this top speed would never be seen with a single speed 56 tooth but I achieved it. Oh and I used a hand file to do it. I have NO idea what my engine is pushing out for numbers.

Nobody here is that stupid unless you cant read. I was talkin bout him posting videos 24 hr in between so his viewer count can go up according to youtubes algorithem, but he doesnt care about views or money or helping to educate those that really do want to know how far these little motors can go. Just like how othe go-kart channels (who are making good money and have sponsors). they dont care they're just wasting their own time half-assing this channel, for christ sakes it not that hard to have an intern do your video editing and voice over for you till it takes off. Im still convinced this channel has so much potential sitting right here , literally a freaking gold mine.

Jason Cung that was a real reed valve. Lol and how fast are you again? Last I checked I was hitting 86mph on a motorized bicycle. Little ole china doll motor.
