    Will work reeds also cause a flooding problem. I will start my bike and it will die shortly after. Let it sit for a little while and it starts back up then dies again. Pulled my feeds off and saw light in the corners of the right flaps. Also saw some excess gas sitting at the bottom of the reeds on the crank case.

    Hi, i have a old Stihl weed whacker "no Reed valves" and after replacing all the seals ect for the "vacuum" section, it still wont work right as skirt to bore clearance which is supposed to me Max .152 mm is more than that. So this loose fit not only dont provide enough suction build up but also the sliding skirt past the inlet port not seal well like a reed valve would and the port and pulse line be almost zero as it seems to be when i test it?

    • @Fixyourdirtbike
      @Fixyourdirtbike  หลายเดือนก่อน

      Possibly. Bad reeds make 2-strokes go crazy. But reeds keep the mix in, bad reeds cause backdraft out of the carb, so it probably not causing the rich mix resulting in 4-stroking. Have you checked your floats/float level/flaot needle?

    I have just done one simple test on my brand new KTM which has small gaps on the reeds. I disasembeld air filter and started engine. I was watching the carburetor intake side during slight throttle opening. I also opened choke to richen mixture.
    I saw fuel mixture coming back to the air filter box at slow rpms.
    I did the same test on Beta with V-Force. The result was the same. I don't know if the reeds have gaps but I going to check it.
    So both bikes don't have good tight reed valve or a little of moxture can go back to the airfilter side and it is normal?
    Any suggestion?

    • @Fixyourdirtbike

But it’s strange because the choke looks like it’s coming up all the way after I’ve turned it and that’s the only way it will stay idling. cr125 1994 btw. I should probably adjust my jetting too

      Yes, and harder to start also probably. They are suppose to sit flush on the cage. If the petals are not damaged/broken/chipped/frayed on the edges, then you may be able to flip the petals upside down to see if they sit flat better. You can usually get more life out of them that way, but a 1mm gap sounds like a lot. New reed petals should be on your shopping list.

    • @Fixyourdirtbike

      No, the reeds have no effect on the combustion chamber or rings. However bad reeds will keep fuel/air from reaching the combustion chamber, which causes a lack of power.

    • @EarthSurferUSA
      @EarthSurferUSA 2 ปีที่แล้ว

      @@Fixyourdirtbike A broken reed will blow back "primary compression", (the crank case pressure), back into the carb tract a bit, so it does lower primary compression, (probably just at lower rpm's), and that means the bottom end is not filling as well as it should, which would then fill the cylinder a bit less and make less power. But because the compression does not start until after the exhaust port is closed on the up-stroke, (sans pipe effects), you should be right about the cylinder compression not effected.

      Fix Your Dirt Bike could the same be said if my carb overlows ONLY after the bike is warm? I reckon it could be pressure from the engine pushing back on the fuel in the float, which opens the float needle. I’ve cleaned that carb thoroughly and its not due to dirt/grime. It only overflows when the engine is warm and then it flows drastically.

    How does the valve close on the down stroke

    • @Fixyourdirtbike
      @Fixyourdirtbike  7 ปีที่แล้ว +1

      Each reed petal is like a spring and closes on it's own. That's why you loose power when the petals get worn out. When they can't close they let the air/fuel mix back into the carb instead of up through the transfer port.

      Fix Your Dirt Bike would this cause a no start situation?

      If the reeds are bad enough, yes, but it's not likely.

    some one told me if they are bad it can mess with the spark plug is this true

    • @Fixyourdirtbike
      @Fixyourdirtbike  7 ปีที่แล้ว +1

      Not directly. But, with unburnt fuel accumulating in the crankcase, it will eventually richen the air/fuel in the cylinder enough to foul your plug.

    can a faulty ree valve be considered a cause foe a smokey exhaust?

      It's possible, but you most likely need to repack your silencer.

    • @Fixyourdirtbike
      @Fixyourdirtbike  7 ปีที่แล้ว +2

      Justin Purton I just now realized what you meant when you said turn them over. I have never turned the petals on any 2-stroke I've owned. I was told long ago that the fatigued petals have a higher chance of breakage when turned.

      i know this is an old comment but i had to speak up. i have the v force 3 reed valve in my 2001 honda cr125 i have had my petals reversed based on slight outward curve they are still working 100% even moto tassinari who make the v force reed valve say it is totally fine to turn the reed petals around with no issue just get a spare set of petals ready to replace THEM they wont be to good after they have been turned. I KNOW THIS IS AN OLD COMMENT.

    • @Fixyourdirtbike
      @Fixyourdirtbike  6 ปีที่แล้ว +1

      Reed valves will cause fuel issues, but what is your carburetor jetting like? How long since your last reed valve service?

    • @kendolbowens1049
      @kendolbowens1049 6 ปีที่แล้ว +1

      Reed valves looks fine to me.cant remember my jetting I will check but if I put in a new plug it start fine rides like for and hour or less wen u stop it won’t start again put a new plug and it starts and ride again and the old plus is dead

    So the reed valve is pretty much the powerband?

    • @middlesiderrider
      @middlesiderrider ปีที่แล้ว

      No. The powerband is the rpm range where the bike makes the best power/usable power. It varies due to many factors. Such as; you could have two different expansion chambers, and on the same bike one might make power down low while the other makes power at higher rpm. Changing the expansion chamber effectively changes the powerband, or the rpm range that the bike makes power

    • @Fixyourdirtbike
      @Fixyourdirtbike  5 ปีที่แล้ว

      HAHA! I think that only works on water though. But the length would make for some great fuel atomization if it could fit.

    • @Fixyourdirtbike
      @Fixyourdirtbike  7 ปีที่แล้ว +1

      Noticeable power loss in high gear, and look for fuel/oil residue in your carb throat between the slide and the reeds.

    • @Fixyourdirtbike

      The reed valve was built into the original design of the 2-stroke engine that was patented in 1894 by Joseph Day.
