There is a lot of tradeoff when it comes to our single gear motorbikes. If you use a larger sprocket, your max speed is limited by port timing and how well the crank is balanced. With a smaller sprocket, you need more engine torque to pull away from a stop but you can achieve greater speeds at lower RPM. To increase torque, you can delete the base gasket (increases compression and gives less exhaust duration/blowdown), use a high compression cylinder head or sand down the top of the cylinder until you have between 130 and 140psi compression, add a reed valve/windowed piston, and stuff the crankcase. To increase top RPM, increase exhaust duration by raising the roof of the exhaust port (don't overdo it!) and installing a larger carb to allow more airflow.
A expansion chamber is a must for low end torque.
I hated the 44 tooth sprocket, I like to cruise fast. Currently I'm rocking a 28 tooth and getting over 40 mph top speeds. Sucks from a dead stop though. I think the 36 tooth will be ideal.
Only think I like about my 44 tooth is torque bot for top speed is trash
Can you get going from a standstill using only your clutch and throttle with a 28 tooth? It sounds like you’d need to peddle.
Yeah, it would take feathering the clutch forever otherwise, and it is obviously quite hard on it.
@@aidenmarshall6478 you also need to pedal to start with a 36, and a 44
When stopping then going at stop signs, you need to use the clutch, pedal a little whilst letting out the clutch slowly with some gas, and she will have way better acceleration for traffic
I know in this video I did not do that very well but I do that now and with the new chain I have it is better.
Only problem with that is it wears out your clutch. But for a gas bike in my opinion when the clutch is worn out it works better becuase for mine it’s so far gone I don’t even need to petal from a stop. I just slowly let out my clutch and slip it all the way till like 10 mph when it’s fully engaged
Great video
Nice video. Bike is riding well. 👍
Hey how's it going I see you made a new video and it looks like you got your bike running good motorized bike life 🚲💯👍, and I'll subscribe
Good Point on the Lower CC ---Now if ya all wanna boost speed you can go small Nitrous , super easy to install , or use a E Bike Tire BOOSTER ..which connects to the back seat pole takes 60 sec to install ..you can also use a toggle switch to get in the booster ...JZP Yuma AZ
I run this sprocket on my 66/80 ebay special. Goes up hills and runs at 30 pretty easily
My BBR is a 66-80cc stage 4 kit and it goes 32 on a 42 tooth sprocket. My BBR runs smoothly on my champion huffy looks good too. I'm wanting looking into high performance to increase horsepower and speed
Just got that new stinger chopper frame + the stage 4 bbr kit. I know a lot of people are hating on the stinger frame right now but I'm 6'1 215 lbs, I fit well with the seat all the way up, and it feels well built except for vibrations at high rpm. Havent gotten a Speedo yet, but with a 36 tooth sprocket and about a quarter throttle it's probably doing 20-25 ish. Very peppy motor, but unfortunately I can't use the banana pipe because it doesn't fit. Probably just gonna have to modify the stock exhaust
This bike sounds very healthy, I wonder what you've done to make it sound so happy (apart from fixing intake leak with duct tape and clamp)
Nothin much other than treatin her right since I got it. Always break in fully with richer mixture. As of now, I have about 3,900 miles on it. They don't really last this long, over 25mph it really doesn't like but anything slower in neighborhood is fine.
Great vid though!
Is it possible to start without pedalling from a stop on 36T?
If you are talking about taking off from a dead stop, I would not recommend it. I've just barely done it once. These clutches are meant simply for engaging and letting go of the engine's power, they are not meant to slip. It will not only take forever to take off, but it will very quickly destroy your clutch pads. If you cannot pedal due to an obstruction or mods, consider one of the wider pedal crank sets to extend your pedals out further.
If you take the air filter cap off and you take the cap off the muffler you will double your hp yes literally double so try it and let me know how fast it goes after that
How fast do you think your 44 can go? I’m debating about buying one
Either the 44 and all stock I got to 31mph maxed out.
Sorry, I meant with the 44 tooth, not either. Autocorrect.
I have a stock motor, and am about to install a 38 tooth, probably gunna hit upper 30's maybe kiss 40
Yeah just 2or3 teeth can dramatically change gear ratio don’t go too big or too small.
Should be lubricating your chain atleast once a week anyway they always rust if you dont. Rain humidity moisture keep it with nice oil clean with a rag beforehand if it's dirty with oil.
is the lever on the left a clutch lever?
Yes.
Try a38or40 tooth you will get same speed and faster and more power going up hills
hey...I watch a lot of videos to see what I can do to improve my two bikes...I just ordered a 36 tooth sprocket, can't wait till it gets here. Did you run your bike on that speed test with that sloppy loose chain? Man, that's dangerous. if that chain ever came off at speed because it wasn't tensioned properly, you could very easily go right over the handle bars when it does come off...slide that whole tensioner back towards the rear sprocket. I'd hate to see you get hurt havin' fun man...PEACE
Since this video I have gotten a new chain that doesn’t turn to rubber after 3 rides. It’s always properly tensioned.
Where did u get the motor that style is rare
Got it from Amazon like 3 years ago. It’s a motoos 66cc 2 stroke engine kit.
how many cc's does that engine have?
This engine is a 66cc 2 stroke.
U don't need to take links out the reason ur chain loosened is most likely do to the chain tensioner vibration loose just move it back towards the wheel and it'll tighten
You should look into porting your motor you can get 45mph with that sprocket
I hit 45 without porting just got a good exhaust
@@2strokeunlimited2.06 what kind of exhaust you got
I didn’t make a video about it but with my f2 thruster pipe and a hell of a lot of tuning I got my bike to 45 as well. My air leak got worse though and I took the pipe off. There might be another video tomorrow so look out for one.
38cc won't pull at all with that sprocket,, 49cc will handle it but peddling required for sure, and the slightest hill will annoy you,
66cc or bigger is suited for those sprockets.
As to your chain, a bike chain is not under the torque or stress as the drive chain for the motor, decent budget chain lube will keep your chain moving freely and won't prematurely wear out the rookies or open up links.
Upgrade to a stainless 415 chain 110 link, PJ One chain lube once a week and your good to go 👍.
Oh yeah, I don't slip my clutches, I peddle and just let it out quick and gas it, usually 3-4 pedal rotations is plenty for my bikes to pull me
Great information Thanks
I had a 40 tooth on my 49cc was the worst 😂😂 but got it up to 32mph down hill
Only 100 cc can pull that sprocket well.
I'm making 31 mph flat out of mine it is a heavy ass beach cruiser 44 teeth spocket I can maintain 25 uphill . On a light road bike these motors can get you to 50 mph.
Move the chain Tension more back
Not fun to have the chain fly off on one of these. the chain gets stuck between the rear sprocket, and spokes. It locks the rear wheel up, and need tools to get it loose.
I had an old chain in this video. It was junk so I got a new chain shortly after and I made sure it was tensioned properly.
You be /#5%$% then if you had an emergency stop! Get your brakes updated. SAFETY IS TOP PRIORITY, unless you wanna be paying outrageous medical bills. B Safe out there.
I'm hitting 38mph on mine and it's got the 44 tooth
Nice, you must have a quality engine or yours is tuned better. Not 2 motorized bike engines are made the same.
@@WhiskersTheFish all I have done is take the sponge out the air filter and polished my ports and sawn off the inside pipe from the end of the exhaust baffle
I have the yd 100 with the 36 tooth sprocket and top speed is 46 mph. I have a 29in bike with a solid frame and wheels. I've ported the jug and I want to go faster any suggestions
You can try a reed valve kit and super clutch. Pretty expensive but can give you much more power.
@@WhiskersTheFish yeah I think the yd 100 is a good start and yes the reed valve kit was what I was thinking about. Just don't know much about reed valves and how they work.
Im getting 37mph on a 39 tooth
Nice, your bike must be running better than mine. My bike never ran perfectly, I'm surprised I even got to the speed I was at.
When i switched the sprocket i gained like 2mph not impressed
It all depends on the engine really. Weaker engines like mine will not gain much at all from this. Mine only gained about 5mph. But a phantom 85, or true 100cc engine will gain a lot from this sprocket. Probably 15mph. When I had a tuned expansion chamber exhaust on this bike(it added about 1-2hp) I got to 42mph with this sprocket.
@@WhiskersTheFish yeah i just bought the cheapest motor around kinda wanna phantom 85 or something cause i know it should be a little quicker than this 66cc
32.6 ly/h 😄 🇪🇸
mine has chainsaw plug and goes alot faster
What's the plug you use?
