Riding Bicycle 40mph with 80cc engine w/o baffle

[noeltheshemale]

you got some nice roads to ride on. hardly any cars.

[wifiman1]

fart bike

[abeemanator]

does your bike still run after riding like this, i did the same thing but the bottom of the pipe got RED hot, and when i would let off the gas, flames will shoot out, i think its pretty cool cause i go faster and have a lot more torque. but im afraid im going to warp the head.

[seanyamaha250]

I don't know if it would work but it would be fun to try a Yamaha 100 cc Kart engine for one of these!!!!!!!!!!!!!!!!!

[cxbra]

@seanyamaha250 Yeah, it could be done. WOW, that would be nuts though! I'd take a kt100 in my minibike tho..

[flaty750]

Hope all these people uncorking the pipes don't get the motors banned from street use!!!

If its a helmet cam, he's not looking at the houses, he's looking over his shoulder for cars.

[nitebomb1]

how long did it take to get

[ohyeahextreme]

its the amount of gear teeth. the higher number of teeth you have the faster you will accelerate, the higher rpm you will cruize at and it will be better at climbing hills. the lower teeth give you more top speed, and less acceleration, however you can counter that i.e. tuned pipe, and carberatur upgrade. hope this helps.

[ohyeahextreme]

my bike goes 48. ive got a 27 tooth sprocket, and a tuned pipe. dellaurto carb, and new wider intake port and pipe off a solo moped. that 48 is on flat ground. i still have a shitload of torque, almost equal to the 44 tooth. climb hills at like 35 too.

[aeTynoT562]

can u explain 2 me what the diffrence in tooth is? like whats the effect for a lower tooth sprocket and a higher one? thanks

[fellafoofoo]

why the fuck are you looking at every house

[ils360]

looking for somthing to steal to sell to get his bike faster LOL

[MoleSinner]

@fellafoofoo how about a car coming out of the driveway... im sure you wouldnt want to hit one of those now right?

[partyguy9]

@fellafoofoo to make sure no1s trying to yell at him for drving a LOUD bike lol

[fishermankory]

r these hard to install i want one on a full suspension bike??plz reply

[linnix13]

wont work on a full suspension bike. you need a hard tail. but they are easy to install

[AmericansSexualPreds]

why u need hard tail what if u calibrate the suspension to be hard

[ils360]

thay dont fit on a full suspension bike

[pirogue29]

Two strokes do depend on some back pressure. Eliminating the baffle altogether can damage the engine and lose some fuel efficiency. If you are going to run it like this better use a richer fuel / oil mix like 20:1. Also a cooler runnung plug. It would be better to invest in a tuned exhaust system from Kings bicycles in Virginia.

[fastboy9]

Your petrol/oil mixture isnt that important, its your air to fuel mixture you want to worry about more, try adjusting the circlip on the carb needle to make it run richer. To be honest though I have ran bikes with no baffle on the leanest setting and the engine runs ok.

[colinkcote]

I am not sure where the needle valve is , unless you are talking about the Idle screw/needle.. I'm going to look now though...TY

[stboo6]

sorry to burst your bubble but your not going 40mph they go toped out with the engine about to fall apart at about 25 you font even have a spadometer so how do you know your going 40 lol i mean come on

[Bnewman8629]

i have one, and broke it in, my top speed was 29 mph with speedometer, on a partial downhill, but going up hill after that was 25, but on a straight away i got a consistent 27 mph

[colinkcote]

It sure as hell will do 40 I weigh 225 pounds and mine is doing 36 , with a 34 tooth alloy sprocket on a 700c Bike. And I do have a speedo.

[Shadeslay7]

I agree he wasn't doing 40. But these can do 40 with the right modifications. Port the intake/exhaust, high grade oil so you can run leaner, upgraded wire/plug, smaller sprocket, tuned pipe and thinner head gasket you'll reach 40-45. I've hit 38 without even totally stressing my motor, I use a jack shaft, have upgraded everything except the head gasket and the expansion pipe. At that point your biggest problem is vibration at high end. I'm not after the top end, just the low end torque.

[heemlo]

removing the baffle increases engine efficiency while increasing noise + vibration lol enuf

[Mustangmike232]

that sounds good"

i want to try that on my bike

hope it wont hurt the engine.

[Fentanyl3]

I'd put money aside to purchase another engine in case, removing the baffle allows the engine to burn more fuel which equals in more heat, depending on the extent of excess heat created, and the quality of the engine materials, it can burn the piston, seals or valve ports. Considering this engine is made in China, i'm sure it's not constructed of the greatest materials available to engine makers, don't let me slow you down though, I'm most likley going to do it to mine when I am finished with it

[Mustangmike232]

yeah,

oh cool

your working on a bike!

i got my schwinn running about 3-4 weeks ago.

and i know what you mean by cheap china parts. because my bike would sometimes not run and then run. cheap POS electrical system absolutely terrible. but hey it runs now. good luck on yours.

[EasyHardLivin]

did you know having a baffle actually increases the heat because the back pressure it creates.

[Fentanyl3]

it increases the heat inside the pipe not in the exhaust, not in the engine < a two stroke depends on the bottom of the piston to pressurize the mixture as the piston comes down the piston passes the exhaust port first allowing it to exhuast, and then reaches the intake port the mixture is under some compression so it tend to push the rest of the exhaust out and so on

with a baffle a slightly larger amount of co1 and co2 etc.. remain in the engine, thus decreasing ignition temp

[patty14chyguy]

no shit
