How To Install a 4-Stroke Engine Kit on your Bicycle - 48cc - Motorized Bicycle

[@dalepress1581]

Dude went from Napoleon Dynamite to Bobby Hill in the course of 13 minutes!!!

[@derekpirie9188]

9 Years later Oct 2022, this early BikeBerry installation is still good today.

[@bikeberry]

You're correct. Adding the engine oil is definitely a pivotal part in getting the motor running. I'll add an annotation. Thanks for noticing.

[@Nehmo]

9:22 You can use compressed air to remove the handlebar grips. Stick the end of a tube air nozzle under the grip and blow.

[@Allyoucaneatmeat]

Or wd 40

[@randolphmarshall]

If you pause at 12:47 you will see that this bike does not have clearance between the crank arm and transmission housing, making conventional riding impossible. If you run out of gas or the engine quits, you will be pushing this puppy. It is also a good idea to make certain that oil is present in the crankcase in the correct amount BEFORE adding fuel...

[@Jeff46u]

You can tell a good mechanic by the tools they use! Slip joint pliers are not made for hex nuts but a open end or box wrench is! If I saw someone using a per of pliers on my bolts or nuts unless stripped I would come unglued! Been making my living work on motorcycles and doing machine work for 45 plus years!!!!!!!!

[@BlueRidgePerformance]

100 % correct. Use the correct tool for the job.

[@bikeberry]

Yes, it's a 26" Micargi Men's Tahiti. Keep in mind that they recently made a design change where the cranks are designed for forward pedaling which means the crank housing is in front of the seat post instead of underneath it. This makes installation a little more difficult, but still doable.

What name of a good 4 stroke kit motor wise

[@dmitriyrusachev2034]

How are you doing, I see your video was published long time ago, I got a question: What is the right name of a new crank shaft you use on approximately 4:40 in your video? Is it threaded 3 ps crank shaft? Thank you.

[@J2Me]

Please make a video on how to install electronic starter in 4 stroke or 2 stroke engine.

Thank You im plaining on putting everything on now in next week. Thanks alot bikeberry!

[@dms12345]

My kit came with the transmission separate from the engine. Do you have instructions on how to assemble?

[@787305pilot]

Also , removing the clutch springs improves clutch and overall motor performance. It allows the clutch to fully grip at low RPMs

[@williamsporing1500]

I tried that, and my bike stalls at idle because it grips. Yes, I played with the idle speed, but couldn’t get it to stop so I put the springs back in.

[@lukeWiz44]

you really just gotta bend them a little. there’s a video on here that shows that pretty sure.

[@a1930ford]

Your website for BikeBerry shows a couple of different complete four-stroke motor kits there. Which one is this kit?

[@victorlinphoto]

Hey BikeBerry, could we get a video showing this 4-stroke installed on a typical hard tail mountain bike like a Specialized Rockhopper? Also, does installing a motor mean that the front derailleur and 3-speed chainrings can no longer be used?

[@ELIRAXPRT]

I would think that motor shelf might get in be way of the derailleur mount. If the crank has to be replaced to allow for the thickness of the engine and mount to clear the sprocket then I see it being a problem

[@Makerdude23]

Great job on the vid! Question: Does the geared transmission slip? I've heard that can be a problem. If so, what can you do to correct it? Thanks again.

[@jasonsmith4243]

What was the reason for drilling the hole in handlebars

[@jacobellinger8027]

it's because the clutch has a dimple that fits into the handle bar to keep it from slipping.

[@jackeline1027]

Thank for you time and show put together motor bike.

[@bikeberry]

Always glad to help.

[@bikeberry]

You have to use the pull start.

[@valentinmelendez8650]

Is there a way to improve the clutch

[@RickWeberSR]

Is there a tutorial for doing this on geared bikes? Also my friend has one, and it compression starts, and has a clutch. What kind of build would I do for that?

[@Cozcacuauhtli]

Good job

[@brentsmith933]

How do you put the muffler on. The bolts protrude from the engine and are to long. Looks to only fit the stock box muffler it came with.

[@eventsmorewithchrisg]

last comment, I'm thanful that in a lot of areas, these type of gas bikes don't get you hassled by the cops. Lets hope that entities like the DMV/RMV don't change the rules concerning street legalness for gas powered bikes, that'd suck

I have this motor and need to know where the fuel lines connect to the carb, there are three nipples on the carb.

[@Jmo6570]

Just learned it's the bronze one

[@sergioaquino553]

My engine came with 2 fuel lines coming out each side of the carb, what do I do with those? I know the bronze one goes to the tank

[@Jmo6570]

@@sergioaquino553 the one on the bronze side I took off that will drain fuel if its tipped over or floods the carb bowl the one on the other side is for draining and storage if you look under it it has almost like valve like on brakes you open that to drain out the hose for storage so the bowl isn't sitting with fuel if you dont plan on using it like me you can cut it short or take it off

what maintenance is required for kits like these and how often? how frequently do we need to change the engine oil? from where can i buy kits that require minimal maintenance?

[@eventsmorewithchrisg]

I bought a 'cruiser' style huffy that's retro style & looks like what you have here. Was wondering about 2 things-1-Where this has "old fashioned" braking (no handle brakes, just pushing back on pedals like on single speed bikes) Was wondering, where this is like that, would I need extra brakes installed to give added stopping power? 2-If I do need extra braking power via extra brakes, this bike seems like it has pretty wide, thick 26 " tires but was wondering if I'd need something thicker to handle wear on tires from braking

[@thomaswilsonsr.9206]

+Chris Geoffrey The braking logic you are thinking about is called a coaster brake, on the rear wheel, there is an arm connected to a plate. That is it. It is typically on a clutch, too. You can always add caliper brakes. Those are easy as well. I recommend both kinds of brakes, just in case. It'd suck if you couldn't stop at 45 going down a hill. In an intersection. Also, if you are using a cruiser, you may need to remove the mudguards to apply the caliper brakes.

[@eventsmorewithchrisg]

+Gage Justice- ok Ty Gage, I'll remember that. I did have a different ?. I have a 49 cc engine Ifrom a 'X-treme 350' style scooter I was thinking of using as the power source for this new huffy of mine. I don't have dinensions of actual motor, but, if you yourself are familiar with those "X-Treme" products, you may've seen what I'm talking about. I think they only hit like 30-35mph anyways, but, again, never having a gas powered bike but being interested enough to maybe create 1, I found this channel. I'm kind of hoping the dimensions work to just mount it the way I've seen others, which usually doesn't include putting on some kind of back carraige just to mount a motor (would be where a basket might go, we'll say, right near the back reflector). Only things now I'd need to get/find out are chain for back tire going into motor (its already compatible it seems with a chain, since that's what drives this x-treme scooter I've had sitting around, the brakes U mentioned, and what I can use the electric battery thats on the scooter for, like, maybe rigging up a front lamp & some kind of turn signals ( was an udea I mentally was playing with, trying to make the finished product more safe if I drive it @ night, bike is pretty dark in color on its own). Once I get started, I may do youtube of it since I have a channel

[@eventsmorewithchrisg]

+Gage Justice-P.S. even though U don't really talk about it here, Thank God for the nice, thick seat thats on this huffy cruiser bike!! I never liked the other type of seats. The one on the bike in this video has one I'd eventually find uncomfortable. I can't think of style names for seats except "banana". The one I have is wgat one'd find on a "crusher" style bike

[@thomaswilsonsr.9206]

Chris Geoffrey Yes, the wide ones are the best. I am not too sure of the names of the specifics, but I do know what you're talking about. Huffy is pretty good - heavy as hell, but the nuts, bolts, clamps and gear joints are pretty much all the same size: 16mm or 10mm. It's crazy helpful. The mudguards are also a HUGE plus, especially after a rainy day.

[@robertsmith5323]

+Chris Geoffrey is SADDLE the word youre looking for?

[@MisterSpaceGhost]

If I needed to replace the motor can I just buy the motor and just reconnect that or do I need the whole kit ?

By any chance would this engine work for a tricycle?

[@Carl-Romero]

Yes i was wondering if we can convert an e bike to a hybrid using this method however I am unsure because of the electric motor being on the back wheel and as well as it also being twist throttle based

[@anthonystorey1333]

Ok i got a question i know it might sound stupid but i don't know. Ok i just got my 49cc 4stroke installed and running but it is still trying to go when in idle and i don't know y. Is that normal? could it be to much oil? please some one,

[@zsfabricating]

+Anthony Storey you might need to add a spring where the throttle cable connects to the carb to keep the bike from idling higher.

[@L3AP2020]

+Anthony Storey The carb has a small screw that regulates the idle speed, so try reducing the idle speed (You'll need to have the engine turned on to verifiy that it won't move) If this doesn't work, you might want to put in a centrifugal clutch between the engine and the shaft that drives the wheels, which will keep the wheels stopped when on idle or low speed, and with the sole speed of the flywheel, the clutch engages and wheels spin

[@anthonystorey1333]

I fixed the problem it was the way the throttle cable was set up it was pulling the throttle on the carb making it stay engaged but its fixed now

[@chriswilson7489]

I tried a 2 stroke motor on a bike with gears. Fit like a charm and they use basically the same sprocket for the engine chain. I had to remove the derailer on my crank transmition to get the motor to fit but I think it's just how my bike was shaped or something.

Unfortunately our engine kits do not come ready for tricycle mounting. Due to the geometry of most tricycles, our engines would not be able to be mounted safely.

[@kevinward9827]

I've installed my engine and everything is working good. Motor seems a little rough and does not idle correctly. Is there another video for adjustments. also does the engine have a choke for cold weather.

[@bikeberry]

Kevin Ward During the break-in period, the engine does run a little rough. After the break-in period, it should get easier and easier to start. Keep playing with your carburetor jet spin to adjust your idle RPM. Check out this video: kzbin.info/www/bejne/jnLEfIZ_fsSpmNE

[@bikeberry]

Kevin Ward There is a choke! It's the small toggle lever near the air filter. At the top position, the choke is completely closed. At the bottom position it is completely open. You can it to be about 15% open when doing a cold start. After the engine is warmed up, then open it to about 75% open.

[@robertsmith5323]

+Kevin Ward yeah theres a choke! probably why shes running rough get on that first

[@a78011a]

and what you do to not die the clutch easy?

[@joshuagordon9143]

Do you have to have a certain bike for this?

[@amealnet2495]

Will the pedal also clear a belt transmission or is a wide crankshaft needed?

[@bluemountaindrivepae]

Starts with a coaster brake on the rear wheel, no brake on the front wheel, ends with hand brakes on both wheels.

On Amazon i see it for $300 from bikeberry but it got a 2 and a half rating should I trust it? I really want this !

Could you mount this kit to a larger frame bike (28"-29") if you modified the chain to make it longer?

[@robertsmith5323]

+ColtWKnight the chain that comes in the kit was way longer than I needed for 26s. it should be long enough easily for a 29 were only talking about 3 inches of chain-----my 26 inch build I had about ohhh 5 inches left after I cut it where I needed it you should be good bro

Do these kits come with 3piece wide crank set for mine did not come with the long drive shaft in only came with the peddles

[@norbertodasilvacosta9899]

Will this engine fit on a Micargi Falcon GT?

[@MrTragicDragon]

You mentioned a 26" bike. Is the 26" the tire diameter or some other measurement?

[@bikeberry]

You are correct, it is referring to the tire size but is a common and widely accepted reference for bike size. Many beach cruisers and mountain bikes have a single "universal" size, leading to any scaling in size also affecting the tire size, which leads to the acceptance of using the tire dimensions for a bikes size.

He said the crank is in the kit. Is it?

[@ampmunkey]

Can this motor be pedal started? Or do you have to use the pull starter?

[@TTYScg10]

I like the 4 stroke, I bet it doesn't die when stopped for a while. I have an 80cc 2 stroke and it has a tendency to die if im stopped at a light. Then I have to peddle through the intersection and then I can use the throttle. I am still breaking it in but I dont think itll ever stop dying after being stopped for awhile. Does any know if it will change after the breakin period?

[@L3AP2020]

+Cassie G You might have to play around with the carb's idle speed, so try winding or unwinding the limit screw that stops the regulator valve. A 4 stroke will give you a lot less power output because of how its been designed since forever (Contains heavy counterweights, that have to be there so the engine doesn't stop when its not on the ignition stroke, so those will steal quite some power). If the problem persists, you may be locking down the engine when the wheels are stopped, on which i would recommend you to install a centrifugal clutch, in between the wheel's gear and the engine's power output gear, and this clutch will do, is that it won't engage the engine on low revs, and when climbing up engine rpm, clutch engages and the wheel will start spinning

[@SavageInsight]
