I hope one day they will manufacture a solid pull start for the 2 strokes .

[@leonardarola]

No, noooooooo. Your pull start is a pedal.

[@tonytaylor5087]

I haven’t tried any of those yet. Maybe I should get one.

[@rdhudon7469]

@@tonytaylor5087 The metal innards are too soft and they break . I have one bike I take on trails and it can get muddy so trying to start by pedalling can give a person a heart attack . I have gone through several and tried modifying them but they eventually die .I've never broken a string , it is always they little metal post that holds the spring in place that goes on me.

[@tonytaylor5087]

That makes sense.

[@fadedum5007]

I’m with you the one I got as soon as I pulled it the string went through the handle once then twice I tied a bigger knot and the I pulled it and the handle broke and cut my hand open and I just had an L shaped handle and then it broke completely and I had to take it off

Hey what's up Tony Taylor I just got a new motor for my giant cypress bike and I would love to get some help with you to get it installed please thank you

[@LordBikealot]

Good video, much appreciated. Ive just purchased my first cycle motor kit (2 stroke 80cc) and I can't wait to receive it and set it up. I need to learn about mod's!!

[@xthe_moonx]

if u put a smaller rear sprocket on ur 4 stroke, u might want to consider getting a smaller front pedal crank sprocket to make pedal starting easier because the motor will have a harder time getting up to speed with that smaller rear sprocket. having gears in the rear for peddling to get to speed is almost essential for 4 strokes ESPECIALLY with a smaller rear sprocket. my 44T gets me to around 50kph but the 40T i got gets around 55kph in ideal conditions. it has noticeably slower acceleration with the 40T compared to the 44T so any lower and u prolly need gears, the front pedal sprocket being smaller prolly wont help much for a 36T rear sprocket.

[@tonytaylor5087]

Nice to know! I’m excited to really dial it in.

Thank you for the very informative video. As not only is this a hobby for me but it is becoming my main form of transportation. Mainly because I'll never be able to own a vehicle or have a license again. So I have been debating the four-stroke thing. With that being said you're very informative video has closed a lot of questions that I had. Now I can say that I pretty much want both of them. A 4-stroke is reliable daily Cruiser, and a two-stroke for fun, more power, top end speed, of course that 2-stroke Power Band, as you stated all the modifications that can be done to the 2-strokers etc. So you're right whether you want a 4-stroke or 2-stroke would completely depend on what your situation is and what you need it for. In my situation I'll need both. Right now I'm working with the 66/80 CC 2 Stroker. But now I know it's worth my while to throw in the money and build a 4-stroke as well. To have that reliable daily driver. As well I think the four-stroke might be a better choice for the winter time. Which would be difficult anyway regardless of what you're driving for a bike, even if it's a Harley, Honda, etc. So obviously in the winter having a slightly lower cruising speed is going to be a safety thing as opposed to an annoyance. Something that'll probably fire up better in the freezing cold as well as allow me to modify things like the tires and stuff to make them like winter tires on a car. Because the last thing I want to be doing in the middle of winter is tinkering on a two-stroke trying to keep it going. The 2-stroke will be my summer fun I'll build a 4-stroke for the winter and just general cruising bike. With that being said though I don't think I'll buy the kit 4-stroke motor. What I'll probably do just buy all the parts for the kit so I have the throttle excetera. And I think I might use a 210 cc snowblower engine. Or maybe it's a snowmobile engine, either way it's a smaller engine with much higher CC. And talking to a person with experience of building these he says it is perfectly possible. So a 210cc 4-stroke or on a bicycle I Can Only Imagine. There is a reliability and all your horsepower. Couple that with a centrifugal force transmission, and you will have a very reliable and fast bike that's a 4-stroke. Obviously this is a project that will take me some time but I will make sure I document it. so if it does work out, people will be able to learn from it.

@@oasissands8584 I sold a car for scrap while locked up to a loser that was just getting out. He wasn't supposed to but he got the registration with the car. I guess he forged the registration and drove the darn car. I guess he ran for the cops one day or the cops found the car or something and put all the fines on me including "tampering with a redgerstation" Obviously the cops put me in jail and they would of known where I was (jail) as they put me there) but they slapped me with all the fines regardless. Now my insurance would be a major issue as well. It would be a lot of $$$ for me to get insurance

[@IdahoEagle77]

What is the speed of one of these 4-stroke engines? Additionally, do you need a sturdy bike frame to support the heavier engine? I've often read that 2-stroke engine kits are unreliable. Many people say that almost none of the engines available for 2 stroke bike conversions are any good.

[@jamessberna1330]

I got a 2 stroke 80cc on an occ chopper bicycle that I just wanted to use as a work ride. There is a steep hill that is unavoidable nomatter what way I go so I need a little more power than it's giving me. Probably going to try to get an expansion pack and a larger sproket for the back.

not exactly a apples to apples comparison, a modded bike vs a stock unbroken in unit. I have a stock 4 stroker slowly getting broken in and have so far braved it enuff to do 34.6 mph so far, hanging on like crazy on an older scetchy frame. I don't see these clutch problems you mention, it seems pretty smooth engaging and ungaging to me...

[@tonytaylor5087]

2 Stroke isn’t modded. Just an expansion chamber. I can see the 4 stroke improving a little as it breaks in but not by much.

[@thatcarguy13]

@@tonytaylor5087 he says right in the video he is comparing it to a stage 4, 66-80cc engine kit. How is that comparable having a 32% and 60% increase in engine size and modified exhaust to a stock 49cc 4stroker ?

What is the best way to modify speed and power?

[@gurjindersingh199]

I cracked the frame on my bike with the 2 stroke motor. I think its not a good idea to use an aluminum frame bike. Most bikes are aluminum frame now days. Steel frame should be able to take repeated vibration a lot better tho. I dont like the 4 stroke fitment, weight and complexities of valves tho. The 2 stroke seems to be a much suited purpose built package not to mention the manual clutch is way better than the centerfugal clutch on the 4 stroke. Centefugal clutches kinda suck in my opinion especially when it comes to lugging up a hill at lower speeds. More likely to slip as the centerfugal forces are weak since low rpm but load is high due to less inertia and incline. Manual clutch is way better. I wouldnt mind one of both. Im currently looking for a steel frame bike to rebuild my motorbike

Hi there, i need some help, i want to build a "mc" like clone bicycle engine military style thing. I can get a few bicycles from ww2 for this project, tomorrow i will get my 2stroke engine..but i think maybe this 4 stroke is better ? It looks more like a type of the first "mc" engines i think with some mods, i dont care about speed, the first "mc" was actualy bicycles with big engines and 1 hp or something, it shall just start and if i get 25kmt with it its ok 😂 thing about it would this be a fun project for the winter ? What will a 4stroke engine cost to my door? Best regards from Norway.

[@fadedum5007]

I’ve had both I sold my 2 stroke but have another on the way anyways the 2 stroke was very easy to upgrade and all those parts I had it all perfect and it was much better in my opinion because I like it louder and it accelerated much faster even with the 36 tooth sprocket and I have a 48 tooth sprocket on my 4 stroke and it’s much easier to build everything comes together and the throttle setup even is super easy but it has slow acceleration but I ride it around and they are both really fun anyway I just prefer 2 strokes

only shitty part about 2 strokes(with manual clutch and over 49cc) is they are illegal on roads in many places where the 4 stroke is legal everywhere if u have the proper lights, plates, license, insurance, etc.

[@rockyrococo2584]

nobody knows what the CC of the 2 stroke you have is. Doesn't matter. Just stamp it 49cc if you are that worried. Or better yet put a 49cc minarelli cylinder( they are stamped 49cc) and get some real torque and speed

[@Black-no1qg]

Most 66/80cc engines are just advertised as such and are usually just 50cc

[@1989chevysilverado]

I got a 50cc 2-stroke and I'm saving up for a four-stroke because the two strokes are fast and they have high power at high RPMs and speeds. but at low RPMs you have less power and I was mixing gas at like 2:00 in the morning and the fumes started killing my brain cells

The problem with the 4 strokes is they are just generic weedwacker engines with some wonky sheet metal mounting brackets and a really chincy and crappy chain take off.

[@rockyrococo2584]

Also the different "stages" bikeberry offers are snake oil. It's all the same wngine just with different decorations that add no actual performance. The ashtray style "high compression head" is total garabage and just over heats as well. The " expansion chambers" are anything but actual tuned exhaust and do nothing that drilling holes in a stoke exhaust wont accomplish. Just get the stage 1 and order a decent head for cooling and get a real exhaust pipe like an MZ and a real performance carb like a vm20 from somewhere else

you forgot the most important part maybe on purpose i dont know . a four stroke is designed to run full throttle for very long periods of time you do that with a 2 stroke your buying new parts or a new engine . two strokes will never beat a four stroke . and there are performance parts you can buy and bigger engines as well that will out perform any china doll right out of the box . and again your test was not fair . you put what looks to be a stock four stroke against a larger modified 2 stroke engine . i would love to see a 50 cc 2 stroke stock against that stock 4 stroke . the difference would be night and day . not being a @zz hole just calling it like i see it .

[@tonytaylor5087]

All good. Appreciate the perspective. That could be another video going into all the running times. This was more of a high level overview answering the specific beginner question...2 stroke or 4 stroke?

[@tonytaylor5087]

Also, the 2 stroke is just a stock stage 4 with an expansion. Nothing else.

[@diydarkmatter]

@@tonytaylor5087 ok so im guessing its a stock 2 stroke 66 cc with a expansion chamber right ? thats still more power then a stock 50 cc four stroke that im guessing is still governed . against a 66cc with proper exhaust and no governor . can you see where im coming from . as far as your stage 1234 it has no real performance as far as horse power . you have already stacked the deck against the four stroke and still barely beat the four stroke . again not being a @zz hole just pointing out the flaws in your test . you want to do a real test match the stock 4 stroke remove the governor and then match it against a stock 50 cc 2 stroke . same gear ratio same set up . bike style . its the only way .

I hear & appreciate your perspective! Let me put it another way. It’s not really a comparison test between two engines. As in this one is better than that one.
