Description

The 2-Stroke Speed Carburetor adds a boost of power to nearly all 2-stroke 48cc and 66/80cc motorized bicycle engine kits. With .72mm fuel jets (larger than the stock NT carburetor that comes with most bike engine kits), more fuel and air are able to enter the carburetor, resulting in higher speeds.

This carburetor has air intake & discharge port diameters of 3mm, larger on both sides of the brass slide, giving you much better idle at a lower RPM than other carbs. Installing this on your 2-stroke engine will have you flying down any track with more low-end torque and better fuel economy than other high-performance carburetors. Whether your motorized bike needs a boost of speed or you’re looking for better fuel economy, this Speed Carburetor will give you the performance you’ve been looking for. 

Parts #13-15, 22-26, and 33-50 on the Fuel Components Diagram

Newly designed 2-Stroke complete Speed Carburetor fits all engine sizes.

The difference in power is "night and day". Receive more power from the larger jet needle slide.

For the BBR Tuning line of bicycle engine, the factory produces a carburetor designed for the 66cc and 48cc engine. The improved carburetor uses a larger barrel slide for the throttle body for increased performance (some models also have a built on fuel shut-off valve). This new carburetor has the air intake & discharge hole diameters 3mm larger on both sides of the brass slide. There is a better screw connection for the intake manifold.

The Speed Carburetor will idle much better at a lower RPM, has more low-end torque and better fuel economy.

Jet Size: 0.72mm

*Note: This carburetor's filter may vary in shape and color. However, the carburetor will perform just as well!

Customers praised this 2-stroke carburetor for notably improved acceleration and performance, with one reporting "2mph gain in overall top speed." Many found it easy to install and ideal for those without jetting expertise. However, some noted increased fuel consumption and one customer disputed its superiority over stock. Overall, most satisfied with quality and delivery speed.

  • Made a substantial improvement in acceleration and 2mph gain in overall top speed. It works!!!
  • Great for someone who does not have the knowledge on how to jet and set up a carburetor
  • Easy installation. Notably increased acceleration. Has a nice healthy sound to the motor.

The carb you sent was nothing more than a stock NT carb with a red air filter. I am a former machinist and I found NO difference in internal meas'. including the jet.In a nutshell you lied and stole my money.lets see how soon that happens again.

Satisfying This carb seems to make my 66cc run a bit leaner at partial throttle. Taking off from low speeds is more satisfying because I don't have to use so much throttle when accelerating from a slow roll.

Mike Grace

Great This is my 2nd one I have bought 1st one is on my bike this one is going on a bike I am building now for someone. I automatically order this carb when building a bike in place of the stock carb. I also get the upgraded ignition. Together it makes a big difference IMO

not the best. but good for acceleration! this carb DOES increase your acceleration, buts sucks about twice as much gas as the stock nt carb. i actually stuck my old nt carb back on after having the nt speed carb on for about 8 months and actually saw an increase in top speed and gas mileage.

T
Terry

Not any better:-| It puts out just the same amount of power as my old stock carburetor but with this carb I have just a bit more power at its leanest setting...

Great! Easy installation. Notably increased accleration. I tuned the carburetor before testing, which I highly suggest. Has a nice healthy sound to the motor.

engine junkie

good for the price dis carb is amazing it took me from going 27 to 33 mph its crazy fast a little hard to instal alone but most carbs are 2 handed it uses a little more gas but its worth the money for the carb and the gas if u want the spped and the thrill there out of stock here but u can buy em at custom motorized bicycle.com same price here and fast shipping

Love it This carb is awesome, and the best upgrade for power, if your running the 66cc cylinder, and have port matched your intake and exhaust. this baby will make alot of difference. also note that mine came with the throttle cable housing cap. but its not shown in the picture. ....im super happy.

I have a stock NT carburetor on my 80CC 2 stroke engine. Would this carburetor also perform better on the 80cc as the **** reviews on the 66cc?

BikeBerry

Yes, our 2-Stroke Speed Carburetor will perform better than the stock NT carburetor due to the larger jet.

S
Steve Pulone

Will this fit right on in place of the NT, or do I need any additional parts?

BikeBerry

Our 2-Stroke Speed Carburetor can replace the NT carburetor.

H
Hobie Hardisty

What diameter air intake tube does this carb fit?

BikeBerry

Thank you for contacting Bikeberry.com! The 2-Stroke Speed Carburetor will fit a 30mm or 40mm intake manifold.

T
Tristan Burrell

Is this carb the same as in photo? Or does this carb have the built in fuel valve? I really would like it without! Thank you.

BikeBerry

Great question! The 2-Stroke speed carburetor will come with a built in fuel valve. Also note that the color of the filter is subject to change from red to black.

V
Vernon Robertson

Thank you for providing the dimensions in the previous question. My simple question will the velocity stack from my stock NT carb fit on this carb?

BikeBerry

Yes, our 2-Stroke Speed Carburetor is compatible with the velocity stack.
