YD100 Bomber Review and Ride Along

This video is about YD100 Bomber. There is a walk around and a ride. THIS IS NOT A SPEED TEST DEMO! I only go 30 mph. It is a new motor being broken in with a 16:1 ratio. The bike does 30mph at half throttle... will DEFINITELY rock when broken in and running 40:1. Thanks for watching and don’t forget to like and subscribe!!!! Thanks.

[@cynthiaroesner1719]

Sick bike! That thing looks like fun to cruise around the neighborhood

[@johnd.5601]

Sounds good you've really got it dialed in compared to some of the other videos I've watched.

[@SouthernCustomCC]

Thank you for your support!

[@senorboardhead]

Really nice concept and build. Good job.

[@bigups1915]

Nice Bike Bro. Setting the bar pretty high for us newbies.

[@abikelife1481]

Well a year later,how are you doing as a motorbike man? What set up are you rolling with?

[@marcusrf7]

Nice looking bike, and good job motorizing it, looks professional. I am in the process of making a CG powered grocery kart with sturmey archer 3 speed hub for transmission. I am disabled and on a limited income, so letting my car go (1987 Chrysler Fifth Avenue) because I just don't have the health and money to keep fixing it up and paying insurance. The kart will get me to the grocery store and back (run on grass, no sidewalk), and then will motorized a Schwinn Sidewinder as a 7 speed (using 24T chain ring only and 34T>12T cassette) motor bike for trips to the doctors and such. At 6,000 rpm speed range will be 22 mph to 56 mph (on paper). I am putting dual disk brakes up front and single disk brake in back. I want to thank you for sharing your experience. I find it very encouraging. Have a good one! FrankyLynn

[@josuemelara5085]

nice bike,well balance. I am not crazie about speed so I have same motor ,but with a big sproket 53 teeth .and a jack shaft.

[@eduardodiaz5762]

I'd recommend CNC throttle, dual brake lever, and some ergonomic grips,maybe Magnesium Wheels. But that's a great build, seems like it's still breaking in,there is a new WC80 pipe its a new bolt on exhaust recently released for Gas Kits, or welded a YZ/CR Pipe.

[@ericmcginnis9413]

Sweet build brother! Dam near what I'm after! In pure Rome of the additions were some what expensive! Like the front forks and disk brake set up but add a jaajpgadt and its pretty much what I want! Now of coarse I would prefer an older beach cruiser frame but you did a great job! I like it a lot!!!

[@abikelife1481]

I have found that down jetting actually increased performance. I am running a .65 in my PK80 motor

[@mbrrideitlikeyoustoleit8436]

Awesome job tho on the bike 💪

[@robbyclark6915]

I’ve got the YD100 on a huffy cranbrook ( all stock) and it gets 30 mph no problem. It feels rough at low speeds but runs nice the faster it goes. Well not all stock, it has a cnc hub adapter and sprocket, 40T. I had terrible trouble getting the rag joint sprocket to run true so I thought I’d try a hub adapter and it works perfect just had to put a little lock tite on the bolts. It’s a nice engine and I can definitely tell the difference between it and my stock 66cc Zeda. I just don’t like the way it runs at lower speeds, less than 10 mph or so. It’s very rough choppy feeling till you get past 10-15. Has nice low end torque though. It gets you moving from a stop much easier than a 66/80 engine. Fun engine with lots of room for upgrading.

[@SouthernCustomCC]

That is a VERY accurate assessment of the YD100. I have noticed that this engine does not ‘lurch’ as much under 10mph after I have skirted the piston. I love the low end torque on this bike, and I am glad you are enjoying yours!

[@sanesaint5705]

And you should mention that you probably have to re jet the carburetor if you put a new air filter on it it better off taking it off and drilling holes through it and putting it back on for more air

[@SouthernCustomCC]

Good rec 👍. Thanks for contributing to the community.

[@MistaWicked2212]

That's a nice bike,I got 1 just like it,what size replacement forks you got on there?

[@sanesaint5705]

It's an orange plastic cover for the carburetor filter easy to drill holes in

[@MattafiedCooking]

Do you have a link for the bike lights

[@Strickn9ne747]

Will the MZ65 pipe fit on a Nel lusso with a bbr engine?

[@rubenpegueros5628]

Does the Mz pipe get hot on your leg? Thinking of getting one for my future build

[@SouthernCustomCC]

It can if you are not paying attention...but do it once and you will always pay attention thereafter. Worth it!

[@Westhelockpicker]

I put the dio reed kit and nitrous kit with a good expansion chamber on mine and it runs great and you should get a good chain tensioner the stock one sucks! Also the top speed will not change! It depends on your tire size and your sprocket size. Whatever they are you will never be able to go faster than that! The more power you add then the faster it will get to the top speed but it won't change

[@peterwinkler8011]

What type of muffler will be more speed and quieter

[@MrThatnativeguy]

Is that a NT carb velocity stack I see? I’ve tried those in the past they create turbulence at higher rpm and can’t be tuned right

[@SouthernCustomCC]

This is the 50mm velocity stack. They have the 45mm 49cc velocity stacks too, but to be honest, I like this one because the event horizon is smooth. Maybe a difference of environment and setup.

[@BeezyKing99]

Another tip, don’t coast on the motor.... its not getting enough oil through the carb.... i used to coast all the time with my first kit.... kept burning out my spark plugs as well as burning a hole into the piston.

[@sanesaint8725]

Okay now we get to see how it rides

[@PlayingWithFireOutdoors]

how did you do the light ?Battery and how to change ?

[@SouthernCustomCC]

The light is a retro 6.5” bobber light. It has brackets that you can use to fasten the light onto the forks. It's harder without the brackets...if your looking to buy one, look for one with the brackets. Check out wish.com or eBay.com. Best of luck 👍

[@peacemaker6156]

Hey did u skirt tha piston on tha intake only ? Im new to this on my first build. Like yours but with a seeutek 80.

[@SouthernCustomCC]

Thanks for watching. These are the long stroke and high hole pisto. Very Minimal skirting is suggested. With the generic engines...yeah...a lot of skirting will be desired because of the stroke length.

[@jamessowles4332]

I would definitely get a spring-loaded chain tensioner though

[@miguel360kmc]

I have both. The chain's make noise didn't hear it with this bike in the vid but i have with a lot of other vids guess its normal idk only built 1. But with both so far about 20miles it runs smoothly sounds way way better than before.

[@ginerbread84]

@@miguel360kmc I'm also considering running both tensioners figure can't hurt lol

[@miguel360kmc]

I do like that pipe... but for my build i like that its all hidden my gas tank covered with bike bag and motor covered bye my legs the stock exhaust blends into the frame.. any recommendations for a good quiet exhaust that will blend in with a cruiser frame like the stock one does??

[@josephgonzalez8084]

Flex poo-poo, you can bend it to follow the frame

[@eduardodiaz5762]

Just get that exhaust and weld the stock at the end of it or get an FMF silencer with your Exhuast.

[@josephgonzalez8084]

That’s the trade off, but it will form to the frame. Get a regule banana or an F2 then

[@chevytruckk3479]

What battery are you using to power that light?

[@SouthernCustomCC]

I thought about a smaller home alarm battery, but the weight was a no go for me. So I put on a 12v AA switch powered battery pack.

[@madmanjames1606]

I NEED HELP I just rebuild my bike piston and head bought a new exhaust and racing carb bike won’t start easy if it does start it isles like shit at full throttle

[@frankopenbrier2742]

What kind of jets do you buy and where do you buy them please send me a link

[@mstzmikebsteviec1119]

What's your gas ratio it just sounds like it isn't going full speed or maybe you're just not giving it full speed for sure cuz I have one and they go pretty fast I Put It upgraded Muffler and everything else and 45 is my top speed on flat ground with a 44 sprocket tooth it breathes really well so I'm just wondering what the difference is I'm yours to mine I have The Firestorm Zeda mother cat and also a motorized bicycle engine kits part chat for another 100 + they seem to run differently slightly

[@SouthernCustomCC]

Yeah. As I said in the video, I was only at a half throttle with a 16:1 ratio. These engines alone get up to 40+\- and with the mods even more. I don't redline my bikes though; so I couldn't tell you top speed. What I can say is potential for top speed was not even close to be seen in the video. Thanks for watching!

[@johng2779]

Lol that's awesome. I just ordered one too! Made from Olyin, got it from ebay seller gomaxind, for $120 with shipping. Engine only though

[@GrlzzIy]

god I can't wait to get one of these new 80cc/100cc engines... will they work work with the old CDI and NT carb? I'm hoping I can swap it right out with my current 66cc/80cc Grubee GT5A

[@SouthernCustomCC]

Adam Riga : I really like these engines. They will work with the stock cdi and Nt carb, but the kit comes with a beefed up spark cable for better transfer of energy and it comes with a NT carb with a larger jet. Both compliment the engine well. If your looking for one for $180, check out my website for an engine kit. Happy building!

[@codelicious6590]

I've noticed that the real power of whatever setup you have doesn't quite kick in until the rings get good and seated- in my experience it takes about thirty- forty-five minutes or so of runtime in varying rpms to get em seated.

Breaking the speed limit with a bicycle

[@ginerbread84]

I plead the 5th lol

[@BuildBreakFix]

Yd100 has massive piston clip problem. @ about 800miles or riding the piston pin will cut the clips off inside the piston and kill the motor. Every Yd100 has it happen unless you buy like wiseco cw10 piston clips. With that said I rebuilt one of these cause of it. kzbin.info/www/bejne/pWqTlat9o7KGjbM I ended up using a reed valve and a windowed piston with 20mm carb. The low end take off and top speed are crazy on a yd100 with those. I did it mostly for power. I can start off on a hill without pedaling and climb hills with ease now with a 36tooth sprocket.

[@SouthernCustomCC]

Keep an eye out on my videos and website...going to have a new style engine that will be the INSANE! Thanks for watching. Since you did all of the upgrades, look at retarding your timing a bit. Have fun!

[@abikelife1481]

What wrist pin clips does it come with? Are they the same as the PK80 or other engines? Or are these clips on this YD100 different altogether than the others? Just wondering if I could just replace with some of the clips I already have laying around.

[@BuildBreakFix]

@@abikelife1481 the "wrist pin" beveled edge in the yd100 cuts the pull tab off the clips like the pk80 uses. Very common! Many people have KZbin videos on it. The motor is great. But the factory clips will wear out fast and fail and the tab will fall off and bounce around causing chaos. It's a 99.9% sure thing. Everyone uses wiseco cw10 clips and this issue is solved. They only cost like 8$. Very easy to change them

[@BuildBreakFix]

@@SouthernCustomCC I cut a whole new keyway when I rebuilt on the other side for that reason. That is why the magnet had two keyways

[@abikelife1481]

@@BuildBreakFix okay yeah I see those CW 10 clips dont have the pull tab portion on them

[@peterwinkler8011]

I have a hyper 2 stroke motorized. I can only get it to 25 mph and i am only 170 pounds

[@SouthernCustomCC]

You may have an air leak I. The intake or exhaust gasket...or even a compression issue which can be solved by looking at the head, the head gasket and the torque specs of the acorn nuts to 13 ft/lbs. If you have an older PK80 model, you may also have the short rod, low hole piston, closed transfer ports, and smaller 32mm intake port. The newer g4 Zeda off my website are solid.
