Popping sound at idle

[04fireshee]

when it is idleing it sounds like it is popping. I have never heard a banshee idle before only 4 strokes.

 

 

Well its not a bang pop like a back fire. Just a popping sound both pipes smoke evenly. Do you think it could be jetting. Could it be that the silencers need to be repacked or something.

 

 

No I dont think im blowing this out of proportion. I think I would know when something is not sounding right and this is not sounding right. When that bit*h sounds like a fu*kin firecracker blowing up behind you you cant tell me thats how aftermarket pipes are suppose to sound and it only seems to come from the right pipe left pipe sounds normal like a banshee should IMO

 

i think you should figure out wheather its backfiring or "popping" when you figure out what its doing then ask for help. im sorry do be an a$$ but you have got every one around here confused on what its doing. everybody has tried to help and tell you something diffrent, you may have made the problem worse if your messing around with stuff that you dont know what it dose, if its just a popping sound then dont worry about it. if its a backfire then tell us its a backfire we can steer you in the right direction.

Ok took the carbs apart today and found out that I have a 25 pilot jet and a 300 main jet. Cleaned the carbs real good and tightend up all the intake bolts a lil more to make sure they are not leaking after I put in all new intake gaskets. Also cleaned all the jets out using a piece of thin wire. Started it back up and I am having the same problem as before. Also turned the air screws in all the way and then backed each one out 1 1/2 to 2 turns on each carb.

 

Obviously 04fireshee is trying to be a smart ass and give me a hard time. It is hard to explain if it is a backfire or a loud pop because obviously a back fire is going to be a loud pop. All I know is that when I put my hand over the right silencer for a second the left silencer sounds good no loud pop or backfire or whatever the hell you wanna call it. When I put my hand over the left for a second the right makes the loud pop or backfires whatever makes you happy you pick backfire or loud pop. I dont see where in the thread that makes you think people are confused as to what I am explaining to them. Seeing as you only have 4 posts maybe it is you that is confused :shrug:. If you are going to post smart ass remarks do not post in my thread I would prefer someone with a little more knowledge on the situation that I am having kinda like the people that where giving me suggestions before you chimed in.

 

dajogejr you have anyother ideas as to why this is happening?

[dajogejr]

I kinda forgot the first few pages of this thread, however....I would've told you to clean the jets with a wire...good for you!!

 

If you already did this, sorry...but if not, switch the plug wires (either wire can go on either cylinder)

 

See if the pop switches sides. I think your jetting is fine. Sounds electrical...

[96_banshee_96]

Switched plug caps right on to left, left onto right and still makes the noise out the right pipe. I am fresh out of Ideas the only thing I am going to do next when I get the tool is measure the pickup gap on the flywheel because I was told this could be the problem also. Do you think bumping up the piolot to a 27.5 and main up to a 310 might be the problem. Bike starts 1 kick w/out useing the choke. If I cannot figure this out then I will have my cousin take a stab at it when he gets back from flordia in about 3 weeks ::

hi i had kinda the same problem a few weeks ago and i found it was one of the reed sets on one side had twisted just a little. im no expert just thought it might give u another avenue to expole. hope you sort it

[96_banshee_96]

yea... I think I will check them out tomorrow. I was told to spray carb cleaner around the intake, reeds, reed sapcers, lower base of cylinders, base of head and listen for it to bog down and that would tell me I have a leak somewhere. I did and it did not bog down so I hope that it is the reed on the right side or the flywheel thing.

If you have an air leak, spraying ether around the intake should make the motor idle faster, not bog down. Pull the right carb off and take out the four bolts holding the reed cage in. Then you can pull the reed cage out and inspect them. The reed petals should seat flat against the metal cage.

I had poping in my rightside not too long ago and me and my friend sprayed carb cleaner around my intake and it bogged down almost killing it. Then we found that there was a hole in the bottom of my intake boot. 96 banshee 96, when I get some free time, I will come over to work on it with you. Your poping is worst then mine was. I have some reeds we can also throw in there to see if thats it

[RagunCajun]

my yz125 used to do it. But after a while it stopped.

 

My banshee does this. Still does i believe. I just thought it was the "firing sound" coming from inside the pipes. I say coming from inside because the sound is muffled and it produces the sound each time it fires.

 

I really never thought anything was wrong with it. Both my bikes from strong and realiable. Starts very easy. :biggrin:

 

come to think of it, not sure if my banshee did it. Damnit, now im confused

Sounds good man. I tried everything and cannot figure this out. Only thing left to inspect is the reeds/cages and the flywheel gap you had mentioned. Im going to check out the reeds tomorrow. Whenever your not busy and get some time on your hands let me know.

i'm not sure if your problem would be at the fly wheel if it's only happening on one side. that sounds more like a one sided problem coming from the intake/carb/cylinder/exhaust on that side. i'd definitely check out the reeds, make sure the carb is thoroughly cleaned, plug is gapped right, etc. check to see if your carb's are in sync too. while the carb is off, take a peek down the ports and crank her over by hand and you'll be able to see the piston. see if the rings look good or if the skirt is cracked or anything. you might also want to double check that both carbs have the same jets in it. that's been known to happen also.

Im going to check the flywheel anyways when I run across a tool. Carbs are thoroughly cleaned used a thin piece of wire to make shure there was nothing pluging them up. Jets are also the same 25 pilot 300 main. The plugs are brand new bought them a couple days ago thinking that might be the problem. I had the guy at napa auto parts make shure the ngk plugs where gapped right and they were. Carbs are in sync. I will take a peek down the ports and see if the rings are good but they should still be good this motor was completely rebuilt from bottom up not even 5 tanks thru it.

[Rustbag]

I doubt it's the stator or flywheel. It sounds like a carb/reed/intake problem. An air leak is the likely culprit if u have already closely inspected the reeds. A reed/intake gasket leaking would make it run leaner on that side, aka popping. Good luck.

When the motor was rebuilt was anything up graded?

[96_banshee_96]

No nothing was up graded but just brand new parts like a hot rods trued and welded crank, New flywheel, new ricky stator with adjustible timing plate. New pistons, New gaskets. The timing has not been advanced because the guy I bought it from never advanced it and I wont feel like messing with it.
