How to tell if your reed valves are bad
Вставка

- Many newer 2-stroke scooter motors have reed valve. Reeds will wear out over time. If your scooter has a hard time starting or has a hard time idling, you may need to inspect your reed valves. Here is the procedure. Please subscribe to our channel.

Its always the vids that are a decade old that are the most helpful
I swear!!
greatest tutorial ive ever watched. how to build credit, homemade pooter tooter/fart sound noise maker, you beat them all
Lol
hey whats a good bore kit for the roughhouse? is it not worth it? have a scooterworks sport pipe, naraku 17.5 carb, stock air box which im hoping to keep, open to buying better parts tho
So thats where that one sound in minecraft came from. Reed valves lol.
🤣🤣
Simple and to the Point, wish all UA-camrs would quit talking about themselves and just Get to the point
Cutting to the chase. Amazing tutorial. Not like half of these youtube mechanics trying to showcase how to half ass do something right lmao
Had a nasty misfire when loading my 250r. Got to the dunes and it just wouldn’t start first thing in the morning. Had to dump fuel in it to start, after that it ran ok, sluggish low end power. Compression tested, 210psi @ 50degrees. Pulled the carb apart. Very clean. Pulled the reeds, and all 4 of the carbon fiber v force reeds were cracked and not sealing
Whoa so straight up about the process, solution, not promoting any products.
Just real content.
I 100 percent agree replace them if they have a gap. if you are in the middle of the woods I need a quick fix then flip them
Rolling Wrench do you have to replace the weeds even if the engine is barely used but been sitting for more than 10 years
DANNYMOTO VLOGS yes my yz85 was sitting for like 5 year reeds where dry rotted and bike gave out on me deep in the woods in florida had to walk it back for like 2 miles
BRO THANK YOU SO MUCH have been having issues with my 2001 cr250 and this fixed my issue!!!! AMAZING VIDEO
Old vid but you just helped me identify a problem iv had with a 25 year old bike! Nice one.
Perfect 👌
@@RollingWrench do u know if not have the reed stoppers on the reed peddles will cause hard start ?
Short an to the point, way it should be 👌
thank you. im rebuilding an old chain saw and the reeds are the last things. and they needed fripped thank you for thr info.
i ran an old homlite saw for a long time with a reed valve made from coke can aluminum.
If you don't know how old your reeds are than replace them, its easier to replace reeds than to dig them out of your cylinder or have chunks come out in your next oil change, however once their replaced flip them at the BEGINNING of every season and they'll last 15 years... just like flipping your rear tire to get another season...
First off they won't be coming out in an oil change because you don't change it to cranky so I owe you change the transmission oil on the 2 stroke they just sent through your exhaust for your reply about your engines dummy
On a 2 stroke,the broken reeds cant come out in an oil change. Because its a 2 stroke,separate crank and trans.
Area open to mix flow in a R-V and cage system is better set at 90% of Carburetor's Venturi or out tube area. For low rpm operation, fewer, short Reeds of hard material do better; for high rmp performance, many Reeds, of soft and light material, and of a long size are the ones indicated. Yamaha re-started using this concept around 1978, and Vic Willoughby / Top Racing summarized their research. Pyramid patented a R-V cage having Reeds opening in the four sides, and not just in two as usual.
one of the best 2 stroke scooter ever made its the yamaha grand axis 100 its design and quality
Sure, flip them around, and keep doing that till they disintegrate and your engine ends up ingesting them... Then you WILL know what happens when 2 strokes ingest plastic (glassfibre etc) reeds..
On a serious note, you should never flip them over. REPLACE them. Pull a set off ebay or something, they are cheap there! Yes, you can flip them as a temp measure, but only provided that they look to be 100% otherwise, ie no signs of chipping, and very slight distortion. If they are damaged (frayed etc) or badly distorted DO NOT FLIP THEM. You have been warned...
AND ALWAYS USE A THREAD LOCKING COMPOUND ON THESE SCREWS!!! You would not believe what I've seen over the years when they come loose and drop in the crank...
Oh stop being a silly perfect by the line and the book guy..some of us are inpatient and are broke..flip those reeds.. I run without an airflter or air box on multiple bikes never had a problem... but I agree red locktight on the screws. But unfortunately flipping the Reed valves on old Motors or really worn-out reeds will only create a leak that your motor cannot seal when it's running because there's a gap now on the edges towards the middle of the read
yeah buy my kids wanna ride there little atv around the yard for hours on end. i don't want to spend money/time on the darn thing and if it blows up i get to enjoy silence... well except for whining kid, my lawn will be happier anyway. i took it out of the trash and it can go right back there
Sara Howard great way to destroy an engine! an air filter costs less than 20 dollars and can save u hundreds in repairs
thanks for the clear and simple answer to my question. I was just thinking about flipping them then you confirmed it
I know this is an older vid but thanks for posting this. I am working on a friends Dinli 50cc and it bogs down doesnt idle right most of the time. I had suspected the reed valves but wasnt 100% sure. Think that will be my next step.
Thanks take care.
Air leaks
I'm gonna check em out on my CR125 cuz the bike has been acting up a little but gaskets are all good and stuff. it's an old bike, really think it's the carb.
Use loctite on the screws too.Ive seen engines eat them.
I think once they need to be flipped they should be replaced as they are reed fatigue and can cause issues at high rpm with hp drop off.
Thanks, just flipping the membrane is enough to make the bike going again,
Can confirm, if you get a used Zuma 50 2T replace your Reeds with Carbon Fiber ones and get a new manifold while you have the bike apart. Feels like a new bike haha.
Good tip! You should always replace unless your in a bind
@@RollingWrench
got a prob with that part 😅
all reedvalves i saw for the DT 125 here in philippines doesnt have a carbon fiber valve, all i saw was steel
Great video ! Straight to the point!
Bro u answered my question instantly I need to flip my reeds
Reeds age and lose their overall tension,flipping them is an old school thing to do. They will never seal like a new reed.
very good vid,thx
Thank you for uploading.
Thanks for the video, very great info, keep up the great work everyone, your doing a great job ☆☆☆☆☆
SO glad to have
You tube ☆☆☆☆☆☆☆☆☆☆☆☆
I figured it out and fixed my bike, crazy but the pipe silencer was clogged lol need new packing but the bike runs better than ever now
Awesome. Thanks. I inherited a KX60 dirt bike. I've only been able to run it for a few seconds one time. It refuses to run otherwise. I removed the reed valve and found a gap in one side of about .040 or so.on both of the reeds. I'm hoping that's the problem. Any thoughts?
Very informative, thanks.
Thanks
Very concise.
Thanks!
maybe you can tell me why my kx500 has no reverseany more and why it smokes when i ride it... great vid by the way. wasted qlot of time taking your advice so i thought i would ask yo more questions during covid as i have much time on my hands now
Just buy new ones they are so cheep if u flip them it's like if u take a piece of plastic or aluminum and bend it in a U shape and then bending it the opposite way in to another U shape it will be malformed and crack also the manual does not recommend flipping them they are 20 to 45$$$ on average
I’m just a 10 year old kid still learning
Mahalos! Thanks
Would symptoms maybe be idling at first, bog and die under throttle, and now won't restart?
im about to do a valve adjustment on my 04 636 and plan on inspecting my reed valves since i have to take them off anyway to do the job, i need to sync my throttle bodies as well and check out all my vacuum lines the bike just seems like it aint running as smooth as it should
Nick 636n8r wouldn't a bike that needs a valve adjustment imply that it doesn't use Reed valves?
wait that may not be it!! my yz85 did that too! it was jetting. stock is 138 main 45 idle. and flipping reeds can be bad too then they are being stressed both ways. I whould buy new jets. they cost about 3 dollars. if that dosent work get new reeds.
My yz 85 dirt bike is bogging in every gear with terrible acceleration its like there is no power band but the bike runs and stays on I'm going to check the reeds and flip them around like you said
Did u find the solution ?
@@franciscocarrero7031 yes actually the damn exaust packing was fucked and clogging the pipe. Took it out and it ran fine.
Good ideeer
Now if you can't get if its been discontinued what do you do then
Can bad reeds make it not rev. My 2 stroke only revs to 2k? This is on a outboard
My yz125 idles but when I put it into gear I can ride it for 200ft before it’s sputter and stops, could the reed valves be the issue? I just did a carb rebuild and top end rebuild.
could be your exhaust is plugged and needs to be repacked, a little late but did you ever find out whats wrong?
so i have a 1991 suzuki rm125 and when i give it gas it just bogs down the entire time no matter what gear i'm in and it smokes a lot. i cleaned the carburetor, tried adjusting jet's and other things but nothing made a difference.
joseph mcneal try replacing spark plug
joseph mcneal Needs a new top end or rings if its watercooled you might be burning coolant aswell
Hey I know this is old video.. but the 2 stroke vino usually come with this white little circle thing that make the opening smaller.. can I get rid of that or does it make the bike not run right without it?
why is the metal part that holds the reed flippng outwards like a ducks beak ? is that how the reeds open up when the air pressure inside the cylinder gets to the reed and opens them up and they max open to the metal part holding them in ?
i have reeds but my metal part doesn't stick out like yours they're held down to the housing with the reeds do reeds vary or are my reeds fucked
Hey are they supposed 100% sealed cuz I got the tinyest glimmer of light. Flipped em and then they bad everywhere
Thanks! :D
Flipping the reeds greatly increases the chances of them breaking which can destroy the engine.
thanks a lot brouuu
will it stop it from starting
Yes, it can.
can you guys help me i have a problem with my 2002 yz125 i tightened the throttle cable and it still doesnt hit powerband it sounds like it wants too but it tops out plz help
it probably has a limiter to keep speeds down for young riders. my polaris 90 had one, all i had to do was remove 2 screws from the cdi. look up yz125 limiter removal on google
Text Missing nvm itm fixed it along time ago it was the carb it needed new jets lol
Juan Rios thatll do it
your exhaust could be clogged aswell
how can you tell the deference between intake exhaust reeds
hello my friend ,I have a problem to my dio2 ,instead work go drive, it work reverse, tell what problem sir. thanks God bless
can your reeds make your bike perform differently while you open up your throttle or when youre going from open throttle to letting go the throttle to an idle. before i changed my reeds it was giving like a clacking sound from the exhaust/carb going from open throttle to letting go. is that bad for your motor if you hold throttle and reeds are bad.
My Reed is chipped slights on the corner it need to be replaced ?
Definitely
Ayeecole yes
Hi for what scooter is that reed valve? coz my pgo big max 50 P1 engine look the same with that
4t scooters doesnt have that right?
yeh i took the screws out and flipped the reed valves round and now i don't know how to put them back in HELP!!!!!!!
Lewis Cocker How are you confused?
I DON'T HAVE ANY REED STOPS!
what are the purpose of reeds?
Reeds are like valves on a 4 stroke. They are basically a one way valve. This allows fuel to be sucked into the combustion chamber. if your reeds are not sealing correctly it is like drinking out of a straw with a hole in it. The suction is not correct.
Fish like to swim amongst them

never do this..........................you will never have a good seal, just replace them, its not like there expensive
Psh, $40 - $70 a pop
Too bad reed valves are 120 bucks
