Motorized bike sound deadening

[BSCHOPPER8787]

USE SOME DYNA MAT DUHHHH

[hiruna1]

ur great with this stuff man :D keep it up.. i wanna make my engine quieter soon, thanks for this

[IcechickenSr]

I would paint the inside with rubberized rock gaurd it takes up alot of resonance and dampens sound really good, and you may still be able to put the inner cardboard bit inside too. I would also do the outside in it too, it is paintable aswell. On top of your current meathods it would help alot. Due to space constraints you are never going to dampen it that great but it all adds up. Cheers mate. IC

[lazydayhohum]

i just left the cover off =)

[MrDbutcher]

Put parakeet feathers in the clutch case n watch out for the black mambas mate!

[MrDbutcher]

Play a littel tune mate!

[MrDbutcher]

Watch out for the black mamba mate!!

[fishman500000]

try getting tome rubberized coating and sprying it inside

[russ244811]

I build these for a living, I can build and repair these things in my sleep. Heres what you do take clutch gear wheel off and lightly coat the gear with high temp bearing grease. dont put to much because you dont want it to get on the clutch disc. By doing this fixes the problem every time.

[JamieMcClanahan]

@russ244811 he lives in china and they work in their sleep thats why these motors are always sleeping instead of running BS,

[harponercam]

There is a commercial product out- with dampeners that cover the gears and the clutch covers on the other side of the motor- They have some kind of absorbent material foam rubber, covered on the outside by aluminum. They are pre-cut form fitting and have adhesive on the out sides to stick to the motor's covers. A couple of vendors at Motorbicycingcom sell them- Pirates and Sick Bikes on the web. about $20 shipped.

I'm going to make a "before and after" vid I'll post up here

[lamontsanford33830]

This video should be about 9 minues shorter. Who gives a fuck about all the bullshit this clown is mouthing off about?

[oscarfish48]

@lamontsanford33830 I do.

[pnutsnz]

HI BRENDON WHERE DO YOU GET THAT TYPE OF FUEL TANK FROM  AND HOW MUCH ARE THEY? GOOD VIDEO 1

[HAZZASIB]

Put some of that red Really thick gear grease in that. Its what we use at work and it quiets the gears so much!

[pattyaaron]

There is something called "dyna mat" it is a rubber pad that comes in a roll and is used to deaden the unwanted resonance in automobile body panels. It was designed for autos with HIGH powered stereo systems. I have used it, and it should do the trick nicely!

[pontiacpanic79]

Listen the the guy who made this bike. I am a master small engine technician, you cannot put oil or and liquid in the clutch housing. The only thing you car use is grease on the crankshaft.

[skutits69]

dumb...you know that carboard will get eaten up by the gas and oil and just gum up your gears.

[brendonv101]

@skutits69 Its a dry clutch, so no oil. Also no fuel could get to it. If there is then there would be a bigger problem then noisy gears. Please dont comment calling me dumb when you dont have your facts straight.

[cjmotorsified]

@brendonv101 it is supposedto have oil or greese in the clutch and the cardbord is a bad idea cause its just going to get ripped apart nd cause problems

[brendonv101]

@cjmotorsified Its a dry clutch so it shouldnt have oil. Grease yes which it has.

[yamahonkawazuki]

@brendonv101 aye it IS greased. ive built many of these and am familiar with them

[frozenveinz1]

@brendonv101 Nope not even grease. the clutch should be dry, if any grease/oil gets in it slips like hell. The gears are what need grease.

[pyroman675]

@cjmotorsified dude u dont want oil or grease in a clutch cause that will make it slip and every thing will stick together maybe causing something to mail function and the grease will just end up getting burned off any way making a bad smell possibly causing a fire

[cjmotorsified]

@pyroman675 When i bought the motor there was oil in it already but it made the clutch slip so we put waterproof greese in it and its been fine. If there is gear noise that means the teeth are clanking together and if you put nothing on them the gears will just grind and wear themselves out. thats why i have the greese in it in the first place. Also it doesnt get hot enough in the gear case to cause a fire and greese doesnt burn easily so its not a problem.

[pyroman675]

@cjmotorsified and grease also catches dust and stuff and holds onto it. and they put oil on it to keep it from rusting and to keep it clean. but if its a wet clutch yes, you use oil

[jsugar72]

@skutits69 toally right - do not try to sound proof that area - if excessive noise is an issue remove the cover - no more noise.. try it

[TheWezid]

impressive young man

[gareth5000]

Paint the inside with latex or coat it with epoxy.

Sounds like a bag of chisells, lol.

[brendonv101]

@gareth5000 hrmm never though of that. Anything really just to give it more mass. 

[HostileHST]

They make a rubberizing spray in the same type of cans as spray paint. Just spray the inside and outside, no need for a gasket then either.

[tothehouse34]

u truly need to work on ur camera skills, i coult not even take more than a minute of any of ur videos because u were making me sick!

[MotorMan20091]

nice bike man i like it 5/5

[10blood]

I hate those engine kits. I went electric and I get more mileage per day and quicker acceleration.

[taxskrem]

did u bike idle as soon as you first installed it. ive got around 10 tanks of fuel and it still wont idle.

[brendonv101]

@taxskrem Yer it idled first time. Ur idle screw may be out to much. Just turn it in till it idles. Its on the left side of the carb above the bowl. A lil screw with a spring, just turn it.

[johnbevington]

You most likely don't need your chain tensioning wheel on the motor chain just take out a set of links if need and pull the wheel back, or if need be put in a ½ after taking out a set of links (1 inch of the chain length) to better get the right chin length. You have the back derailleur on the pedal side for the right tension on the other side, I use the plastic wheel tensionor on the pedal side because mine is a single speed.

[johnbevington]

I thought why put all that ware on the plastic wheel & use up some of the energy of the motor, & it's a little quieter now. Ive been riding all over town this way and it works great. Once I get my ½ link in the mail I dont think Ill have to use the chain idler at all. In the directions is does say that A chain idler is used to tighten chain if needed. If needed, is the point.

[johnbevington]

I'll let you know how the ½ link works. But never the less it does not really matter because I don't pedal that much to matter. Did you ever notice that the word pedal is kind of confusing, I mean you have Pedal, Petal Peddle. Like in Spanish you have, Pero, Pedro, Perro. O well best to you.

[tristanharmer]

how many tooth are the sprockets and what ratio are they please reply???????????????????????

[halopersin]

jw were did you get your kit and for how much cause i bought a 68.5cc kit for 75 us dollars and i dont know if its a crappy kit ill post a vid of it when it comes in the mail thx for the help

[1mike66]

hey how much did u pay for ur speedo coz i have the exact same one. 84 bucks ??

[brendonv101]

84?? no, i got it for like 14 bucks or something.

[malgez]

damn! i just found out i could get fined $500 minimum for riding my motorised bike (like this one) in SA!

[NickSkitz]

You could, (if its only the gears in that section) drill a hole in the casing fill with a bit of LSD (Car Diff) oil and put a small bolt to seal

[Inkv7]

thats a nice bike...and a nice engine..the color go's really nice with the crome on the engine...sound nice but the gears cover dosent...hope you can fix it...but the over all look and sound is really good

[porche3r]

what kind of motor is that

[brendonv101]

Zbox 49cc engine.

[geoff390]

Hehe milo cereal box?

Shame it didnt work as well as you'd hoped.

[brendonv101]

well it worked well but didnt cancel it out completely.

[iakazul]

Lol I used a Pizza box!

[Cchange4us]

add some thick grease to the teeth, that should do it

[spitzification14]

@Cchange4us

[brownbeaverboy10]

that Z makes it look like a badass big motor or sumting

[elemineseslapolla]

im not trying to be smartass but man, its an engine it must have sound, your engine sounds perfect, i wouldnt do anything to it, but yeah its your engine

[zaty22]
