An engine's bore is the diameter of each cylinder, while the stroke is the distance within the cylinder the piston travels. Basically, an engine's maximum power depends on how many rpm it can produce. The more rpm, the more power strokes, the more power it produces overall. So it makes sense that the most powerful engines also rev the highest. Because a piston with a short-stroke doesn't have to travel as far each cycle, it can cover a greater distance in the same amount of time versus an engine with a longer stroke and smaller bore. That means more rpm. Similarly, a bigger bore means bigger valves, which means it can take in and push out more air in each cycle. And more air means more power.
It works in the opposite direction, too. Let's say your aim is efficiency rather than power. The best engine to have, then, would be one with a small bore and a long stroke. Why? Well, it's a bit more complicated than the power equation, but it involves surface area. Basically, the more surface area a cylinder has during its combustion, the less energy is lost to heat, resulting in a more efficient cycle. - Авто та транспорт

You just have a great knowledge of bike
That is a complete video, Great effort Bro...
Thanks a ton
Jazakallah
MashAllah apka content acha hai Inshallah Allah apko kamiyab kre...♥️
Or Ybz ka b btaya kre
Thnkz for great explanation 💯
❤️🔥
Gpro ki footage awesome ha
💯👍
is there any advantages of using high octane fuel for YBR, considering 10.1 compression ratio?
Please make more video don't quit
i.a bro keep lovin
Hey brother i wanted to ask that i have ordered moxi airfilter for ybr 2021 and can i use main jet of 116 in summer and 118 in winter? as im in karachi
hi sir
can i use 13t sprocket on ybr g
and its effects
Bro cb 150f ki top speed par koi video bna do .
Asalam.o.Alikum bro ap ny carburetor tunning py vedio bnai thi us ma jo 118 ka jet kdr sy purchase kya tha?
shahab bhai the product is not on daraz for yamaha yr ab nhi mil rha kaha se lu can u telll bhai
Very informative video bro
Proud of you that you’re sharing knowledge and your passion with engine
5:50 isko kia ho gia bai 😂😂
Thanks so much brother
haha 125 :P
*TAP SPEED OF ONE 2 FAEEE*
honda cb 150 per butterfly cubature lug sukta hae?
Bhai ybr g smoke problem ki wajah se 50 ka piston bore ker k lagwaya tha lekin subha subha abhi bhi thora smoke deta hai bike kya wajah ho sakti hai kindly reply plz 🙏
Aoa
Can you make a video on Suzuki gd110 performance increase?
I think gd110 & ybr both uses same type of carburetors..
Mera ybr stock ha bas halka sa kuj carburator me setting ki huwi ha, 111 GPS ki speed par jaata ha lekin 4th gear me 5th lagane se speed kam hona shuru ho jaati?
Ybr g 15 model hai magr white smoke kar raha hai koi idea..........q smoke kar raha.
I think that this topic is bit technical so you should explain it with the help of proper diagrams and illustrations. 🤔
Thnx
@@ShahabLodhi Asalamualikum shahab bhai one question jesy k ybr ka piston 54 mm ka hy agr is mein 125 honda delux ka piston dal dein jo k 57 mm ka hy tu is se ybr ka CC barh jayega ??
Bro need a complete video on premium fuel vs local fuel.
Also, is High Octane is capable for the Yamaha Ybr bike?
Very informative video... bro plz make a video on gear ratios of ybr vs gs150 vs cg 125 and relate it to the initial torque of these bikes as well. also how can someone increase ybr's initial torque/pick (for steep slopes) by changing something like gears etc. Thanks and keep it up....
He already made a video on this topic just install Cg 125 front sprocket and adjust the carburator settings check his recent video about how to increase ybr pik top speed and mileage in thumbnail u will see 17% increase in performance that's the video
i have seen that video but i wanna know more about the theoretical aspect of the gear ratio and its relation with initial torque. and the comparison of those 3 bikes in this regard. also if we can change the factory gear ratio of ybr or not.?
@@ExplorewithZaini Gear ratio will increase when the front sprocket teeth increase for example 70cc bike has 14teeth on front sprocket so when we install 15 teeth sprocket gear ratio automatically increase plus the vibrations also decreases that's what I know about How to increase gear ratio but if we use 16 teeth or more than that then we also have to change the rear sprocket too to balance the speed and pik otherwise bike will be useless during charhayi specially. Other methods r also available just install spilt fire cable plus install iridium ur bike pik and mileage will increase noticably and after market air filter for more pik and top speed
@@ExplorewithZaini in simple the more the teeth on a sprocket the pik will decrease the lesser the teeth on a sprocket the more pik u get but it decreases the gear ratios and top speed
@@razmakmalik3104 ok. what about the individual gearing inside the engine? for example the gearing of 70cc and 125 is more focused towards the torque side while that of ybr it is more towards high speeds. thats why it has less initial torque. i wanna know if this gearing (and not the sprocket) can be changed or not to get more initial torque...
Bhai suzkuki gs 150 or ybr ki race plzzz zaroor
after an engine rebuild
After market exhaust laganay sai average increase hoti k kam aur kya air mixture dubara adjust karna hota hai Shahab bhae
zrurt ni he mixture adjust krne but thori c bike bethegi
Sir aftermarket exausht ka engine ki health pay asar btayen plzzz
health se zeada performance pe issue ayega
Shahab bhai 1 video ybr ke fuel tank pe bih bana dein fuel gauge sahi kam nhi kar rhi to kesa thek kra ya kya issue ata ha
No they are different, No EFI came on these engines
Very knowledgeable video, shahab bhai. Mein ne suzuki gs 500f sell kar di. Aab Pata nahi sahey Kia ya galat. us ki jaga per honda cbr 650 khared li. Mileage 30 k Thora ziada chaley hai. Kia yeh baad mein. problem ban sakti hai ?

gs150 is over or under squareed??
Slightly oversquared with lower compression ratio
Does jetting the carburetor damages engine in the long run?
if jetted correctly then Not at all
Salam Bhai. I have removed my Air Duct from my YBR 2017. Do i need to change air to fuel ratio?
Yes follow latest carb tuning video
Just an update. 10 months ho gaey hain. Cbr 650 no issues. Yeh baat mein karna chahta Hon Kay. Newer model cbr 650 slow chalanay Kay liay nahi Bana. Honda nay Gearing long rakhi hai aur acceleration driven bike hai. Not touring or slow daily commuter. Ap ki nayi videos nahi a rahi, busy?
So sorry b busy with the stuff
CB 150f ka engine phir under square huwa naw stroke zada bore kam tau torque zada millay gi horsepower kam hogi am I right ???
57.3 x 57.8 mm yep and fuel average b achi but u need an OHC engine at higher speed
Bro your yahmar video are great. Just want to ask can we change carbtor settings on new running ybr g or after the running when its running will be completed then we do change carbtor stock settings??
you can change whenever you want, thanks for the compliment
Shahab bhai aik sawal so plz answer... RPM limiter kiya cheez hai aur ye kese kam karta hay and bike main kahan laga hota hay ?
it limits the RPM of engine to go beyond disaster. u can feel if on neutral gear u try to pull full accelerator it'll start cutting on engine RPM.
in YBR its comes in CDI box in EFI its different
@@ShahabLodhi can i change this RPM limiter ? Its useful or harmful ?
@@FMR79 its harmful don't do it
@@ShahabLodhi Thanks a lot bro... Aap ne top speed Increase karne k liye jo video banai thi wo he best hai...
Jo mirror kam ka hai wohi Nahi hai😂😂 Left wala kisi kam ka nahi
Lol
Chinese bike i think they have also great torque
Talking about 100 cc bike
I think so
Ybr bike aj kal har ksi k pas he q k engine acha he or qemat bhi thek the jo ab nahi he..3 sal phly thek the..suzuki ki jaga logo ny yama ko targi di .. ab masla ye he k ap ko pata hi he k engin under power he pari elaqa or retila elaqon me fail he lod k sat...keya kary k engin power full ho jy top speed 140 ho jy or peteol bhe zeyada na khy...
watch my carb tuning videos
@@ShahabLodhi bahut Jabardast aur informative video hai carburator wali lekin Yahan loading ke sath Jo power chahie uske liye engine mein kuch karna padega
Need u help for GS 500 carburetor I issue can u share ur cell no
Yes plz contact on my instagram
Bro I changed disk brake oil and now it is not like how it was please bro my disk brake is very weak idk can you make a video on this topic or please give me your WhatsApp number
Brake line ko bleed kren
@@tahahaider5836 bhai wo bhi kar Lia phir bhi koi result nhi hai.
@@gaminggod3813 bhai brake weak tbhi hoti hai jb brake line me air ho ya pad kharab hon.
@@gaminggod3813 ye bhi batain oil kis ka use kiya tha?
@@tahahaider5836 brother oil dot 3 use Kiya tha .
