Top Speed Test (80cc Motorized Bicycle)

Sweet Super Mario Galaxy intro mate!

You gotta let the engine warm up

Something's wrong. My very old 50cc, old gen, stock carb and muffler on a 26 inch mountainbike does 26 miles with no effort.

Top end not great tbh

Would this work with a 80cc minibike engine on a bicycle

What is the maximum mileage per full tank of gasoline ?

Didn't even powerband 😂

what’s the best fuel filter mines broke over and over

You're not achieving max rpms, probably due to poor carb mixture. Maybe too rich.

54

do you still have this bike? if so, do you still use it?

how far can u go with one fuel tank ?

50 mph

I don't understand; I ride a Cranbrook with a mish mosh of motor parts and it's an 80cc. I can go 45 mph easy and that's with the 44-tooth sprocket!

boringggg

So why are you riding on the wrong side of the road?? You as a bike rider should know to ride with traffic... YOUR SETTING ABad Example for Bikers and Bicyclist!!
Now are far as your build... Sounds & runs good, Good Job On Your Build!!
"Ride🚴On"

I don't care how stupid i look im wearing a helmet

The u haul truck did cum out of nowerr

I got my 50cc to go around 30 35 while riding with the cap taken off the end of my exhaust

you need a more performance part my bike going over 50 mph man !!!!! but good job man

im guess maybe top speed off 55mph

I just got my done it is a lot of fun ride it almost every day

I work with these motors if you're not hitting 30 it's a 49cc not 80cc both motors are identical

Turn up throttle and drill holes in carb and take muffler baffle off and that bitch will hit over 30 it will be loud as shit tho lol

41

41

What kind of range you get per tank?

oh damn. I'm waiting for an offset intake to get here......now I'm worried i don't think i'm gonna hit 25!!! i'm 19 6'3 and 190lbs....I hope thats not too much for my 2stroke 50cc

Lots of people just full throttle the bike. There’s tricks to the throttle. Alternate it slowly with the RPMs. Don’t just floor it.

Do we need license to drive?

S*** man and I was worried I was doing bad at45 km an hour sometimes hitting 50 km an hour and I thought crap man there's something wrong is not topping out like it should. But I did the math and 24 mph is exactly 38.62456 km per hour. So I guess I'm doing pretty good when I hit 45 km an hour easily on flat ground and then if I hold on the throttle long enough I'll usually get to 48 to 50 km an hour hit a little downhill slope and she'll start doing approximately51 to 52 km an hour if I'm already moving along at Full Throttle when I hit the downward slope. And that's all Factory Motor except for a little bit of modification I did to the air box also I replaced that cheap crappy factory zc plug for the appropriate NGK replacement I noticed the big difference from that. So after watching this video I'm not as concerned that my motor isn't running like it should if anything is probably running great. So thank you for making this video. Now I'm going to eventually Port the exhaust and intake ports and polish them. I'm not going to bother with the performance carb because these Factory carburetors are actually pretty good minus the crappy air box that's attached to them. I purposely drilled a few holes in that sucker to give it a little bit more breathing space. But those aftermarket carbs all you're doing is playing around with jets until you get the right air fuel ratio which chances are your factory carburetor is already putting out the extra horsepower, if you gain any, would likely be more due to the fact that it has a cone filter on it and it can breathe better. I plan on just buying the cone filter and hacking the factory air box to accept the cone filter. I happen to think that my Factory carb on my china doll is probably running as good as any aftermarket carburetor would especially once a good air filter is put on it. So for performance I plan on doing the exhaust, putting a performance CDI on it maybe upgrading the Magneto, definitely going to get the high compression head, then port and polish the intake and exhaust ports. That should boost her a little bit aside from that I don't think there's much more that's really worthy of investing money for performance upgrades so the upgrades after that would go into better quality tensioner pulley stuff like that. Just don't be fooled by the marketing gimmicks of these performance carburetors. And you should get a lot more speed out of your bike and if it's still being broken in expected to get a little faster as it breaks in provide it your braking it in properly. Don't bother with that 16 to one ratio neither run 40 to one from the get-go I learned the hard way and burned out the plug pretty quick with a bunch of excess oil all over the brand new block. It's a very excessive oil mixture even for a brand new motor how you drive it it's how you break it in has nothing to do with the oil mixture just make sure you don't lean it out too much 40 to one ratio and you're good to go. I learned a lot from the little bit from working on these bikes just recently and watching lots of videos Etc. It helps and I'm already a certified small engine mechanic

So I just bought 100cc two-stroke motor kit and I can't seem to find on Google what the top speed is so what am I expecting stock as top speed? Because I bought a 50cc last time and it would go 25 mph

Oh god that walleye sight from your cam....glad I don't have a headeache. Lol

My personal preference is for the 4 stroke engines. Top speed is maybe 25 at most. True 49 cc so legal almost everywhere. Loads of fun at that speed and do you really want to go faster on a bicycle?

Do you sell parts? I build them and live near utica ride safe bro love the videos

Next😢

Something's really wrong, that thing would be able to spin twice as fast. Make sure your throttle is fully opening, mess with jets in the carb and see if it changes anything, just go over and check everything to make sure you're making full power. 40:1 will make you more power than 20:1 so it isn't that. my 79cc 4 stroke does 38+, you should be able to get that out of your engine too.

I have the same kit type thing and I can get around 30-37 mph at around top speed but maybe I’ve broken it in enough and I’m running 32:1 so it’s linner than most bikes

Thank for telling you size and weight. Really like it that it goes fast. Do cop bother when they see you?.

What type of gas?

How are you not boggoring

I was one of the original importers of these motor kits 20 years ago and have built well over 100 for customers.
I recently just built a.light 29" wheel cruiser and it hits 48 mph . You gotta know a few tricks to these things to get the most out of them
Make sure to gasket seal where the carb slides on , shorten the chain and get rid of the junk tensioner move the carb needle up one notch . I'm gunna port the head and put and aftermarket exhaust on today and should easy hit 50mph. The high pressure 29" wheels really helped the gearing also adjust the wheel hub bearings . The rear hub will always eventually blow up just from the torque the.mortor puts on it

U def connected that wrong

Your bike is still braking in so it’s not as fast or smooth

My 80cc I got to 33 mph

1971 I bought old school 80 cc Yamaha dual sport. Had leveled sprocket on front of .aon rear sprocket. In trail mode it would do forty-two mph with my friend 140 # and myself 130 # on flat trail. 38 mph up grade. I never tried in street mode since it required license. Suffice it to say it was quite powerful for 80cc. It had lights in case wanted to license and it weighed 190 #. So with two people our small size it was hitting on 450#. I find that amazing.

I was able to get 32mph with stock 80cc bike kit and 36tooth sprocket

What milage does the little tank get?

Cool video it looks like a lot of fun I was going to get an electric bike but I think gas is the way to go nice bike man.

What is your market place in Montgomery Alabama am I talking the same person you do come from Montgomery Alabama don't you please message me
