please help!! I wanna buy this bike&engine tommrrow !!

[fatdaddy]

Look down the bucking bar hole with a flashlight to see if the bearing might still be in there. They get stuck in there a lot of times. and ya cant put two bearings in it. I tried to take a pic but my camera is acting funny, fuzzy pics.
fatdaddy.

Not all bucking bars are the same size, but you can usually adjust the clutch to compensate.

 

[Agreen]

Supposedly you can make a "bucking bar" by cutting a drill bit if you can't get one. It's been well documented on here. Ace has ball bearings if yours is not in there. I hate having to wait for parts all the time so i usually end up making what i need.

 

[2door]

The drill bit should be 8mm or 5/16" if you're going to make one but without something to gauge the length you're going to have to experiment. The length is critical to proper clutch operation.
Same for the ball bearing. 8mm or 5/16" in diameter.

As a rule of thumb, the bucking bar should protrude from the center of the sprocket about 1/4 ", maybe a little more.

Are you certain those parts are missing? Absolutely certain?

When I told you there could be a "missing pin" I was referring to the steel pin that retains the cam in the clutch actuator cover. Not the bucking bar. The bucking bar and the ball bearing do not keep the clutch cam/arm from coming out of the cover as your photos show. Only the 3/32" pin that goes in a hole in the cover holds the cam/arm in.

I'll take some pictures later to show you.

You should get a package from me on Monday.

Good luck in your progress!

On post #8 - pic #4 I noticed the wires are sitting on the exhaust header. I suggest you move them away from the exhaust - they WILL melt if you keep them there. And good luck w/your bike, hope it's up and running soon!

 

[mikeab13]

South gate Jonny. Thanks for advice I had them last ke that for photos when I was moving stuff around. But I will need to move it back an maybe zip tie.

FatDaddy: could you show me a pick. Or when wife gets home I'll get heavy duty flash light out an check an take pics. Is it one bearing or a couple like 8? I will try search again but for some reason I get very little results an most are off topic or just have search words in different parts of post.

2Door: please send a link to the post or maybe explain a little more. Will the drill bit be attached to the bucking bar an then into the hole with were the missing bearings should be?? I've watched the link video. Watched the YouTube channel from the guy who makes Fred head he did an engine breakdown an he kinda skipped over the bar an clutch bearings or connection. He broke down in engine in like 8m20sec lol soooo was alittlebhard to keep up. I'm going to keep watching keep reading and keep asking questions until I get this bad boy on the road I can't wait.


Xseler:thank you so much for helping me. out money is very tight and this will be helping me a bunch until I can get to Miami or hopefully the shop in Fort Myers. I'm going to go step by step with pics a lot of questions an yous guy's help on this thread but I will def be pm'ing you when its all finished for you to see it in action first!!!

Looked at what I have at the shop and I cleaned up a clutch cover, bucking bar, and the steel ball that goes in there, that 49cc engine I got is pretty much complete so let me know if there's anything else you may need off this one... it also has a good magneto rotor and coil, all the cover plates, a good clutch cable, and the cylinder head is also in excellent shape. I will send the package tomorrow after work since I needed to pull the parts, make sure they were in good shape and clean everything up since that side of the clutch can get rather nasty with grease, dirt from the chain, and a cheap krylon paint job... I dipped the parts in the carb dip all day today so everything is nice, clean, and free of paint,grease,and dirt. The cover has a decent size nick in it but it wont hurt how it works and I can fix that before I box it up as well. I can also powder coat it black if you need a black one to match the rest of your engine... just let me know since it just takes about 10 minutes to powder coat it. This one also has a name plate on the cover that reads Yang dong and 48cc as well as the manufacture date 2011, I can leave this on or remove it depending on what you want.. its faded pretty badly tho so removing it might be the better idea... just let me know if you want it powder coated black or if you want it clean bare aluminum and I'll prep it for you before I ship it.

 

[mikeab13]

So Monday I will be cleaning the outside with simple green. I'm going to a bike shop an getting a new cruiser style bike and hopefully find something with a front break. After I get bike I'm going to install the rag joint an rear sprocket that Xseler is sending me. Then hopefully Tuesday or weds Davezilla pack will show up an I can get down to buesniess

I tried to take a pic, it came out fuzzy, I'll mess with my camera and see what happens. The bucking bar don't attach to anything. It goes in the hole and when ya put the cover on, it cant come out. If ya look at the arm that goes in the cover has a flat end, the flat end rests on thr bar so when it gets pulled by the cable it twist's and pushes in on the bucking bar and operates the clutch. The bearing goes in before the bar because the clutch spins on that bearing. if ya don't put in the bearing the clutch will spin on the bucking bar instead and chew up the bucking bar..I always pack the hole with grease before I put in the bearing and bucking bar. when ya push in the bar, any excess grease will get pushed backout and ya just wipe it off.
fatdaddy.
this shows a video on the bucking bar and clutch arm. I just hooked up a new computer and don't have sound hooked up yet so I don't know if he explained it properly, but it looked good. As you can see, the bucking bar just slides in the hole with the bearing before it. I didn't see him showing the bearing on the video, but trust me, There IS a bearing supposed to be there.

Hi Mike,
The question you need to ask yourself is do you want some reliable transportation?
Or do you just want something to dink around with and call someone or push it home when it breaks?

My guess is you want something you can trust.
You can't buy that for $50, you can't build one for <$325 buying new good everything and doing it right.

I suggest you make a decision.
Just keep that $50 bike as spare parts and build a new bike.
Or, use what you got for a first build and make it go.

To me it defeats the purpose making a $50 bike go if you buy a new bike to reinstall an old broken engine kit on.

From what I have seen in your pics I wouldn't trust that engine to ever fire up and run right considering how the builder built it, following instructions didn't seem to be his strong suit which includes things torqueing bolts and mixing gas and oil ya know?

To help you along the 'rag' in the term 'Rag Joint' sprocket mount is actually stamped out of recycled car and truck tire sidewalls.

Just 2 rings with 9 holes with one ring split so you can slip it around your rear axle on the inside.

They have a natural curve to them.
This is the inside of the tire side and the side you want to sandwich the spokes with as the outside is not as pliable.

Here is one set I got once, you see the sidewall lettering.

The goal is to slowly squeeze those rubber rings in a staggered way together until they touch and compresses to firmly attach the sprocket while keeping the sprocket true as you go.

This is what kills most builders.

There are good tutorials here for sprocket mounting, just pull your rear axle apart and rebuild it while you have the wheel off, and true the wheel before you put the sprocket on is my recommendation if you want to keep throwing money at the $50 bike.

 

[mikeab13]

My assistant!!! He'salmost as excited as I !!! Gonna have to put a basket or seat on the back for him.

 

[xseler]

Mike, you're gonna have to re-use the sprocket you've got. I only sent the rag joint, arc'd metal rings and bolts --- also provided instructions....and a few extra 'parts'.

Again, best of luck in your adventure!

 

[2door]

Mike, with help like that you don't need us. Your "assistant" looks like he knows more than the original builder of your bike

Seriously, we'll get you up and running. You have some of the best builders/members here helping you through the initial hurdles. You'll be on the road soon, sir.

We're glad you came to us and we're doing our best. Keep taking the excellent advice you're being offered and it will pay off.

Tom

 

[mikeab13]

Xseler thank you. To be honest the sprocket looks straight with no chips or missing teeth so your rag joint will be perfect man.An thank you for the directions I have my phone an then site for a refrence an trouble shooting threads but to have something I can have next to the bike To reference will be a big help.

2doors: to be honest man I think your right!! The motor mounts I thought were good because they wrapped the frame with some type of tape or wrap I think for vibration but everything is loose. Cdi,motor,even the carb is loose. So I'm suspecting this guy jus jimmy rigged it to the bike to sell. But I have a solid motor. Its gonna be a little work but from all the post an happy motorist on here its gonna be half the fun! I really wanna get a grasp of the basics. I just downloaded Gordon Jennings 2-stroke runner an Alexander Bells tunning. To be honest it is like reading Chinese lol but that's because I don't know a lot of the part terms. Is their a thread with bike parts an terms with explanation? Maybe in 2-3 months I will be able to contribute this to the community after I read an watch! Thank you again everyone I sound like a broken record but you all have been nothing but helpful an supportive of a noob with a dream.

 

[xseler]

I think that some of us just want to re-capture some our initial zeal of our first project. you've kinda provided a 'spark' --- at least for me!

Many noobs that have been dealt your hand would be like 'Oh whoa with me, look at what this guy cheated me with!'. But you're like 'help me learn to fix this'. The following web site can help you with anything that is bicycle related, which is a large part of our hobby.

You can't buy that for $50, you can't build one for <$325 buying new good everything and doing it right..(quote from KCvale)

Sorry to have to disagree with ya bro. I once bought an almost complete kit that a guy had on his bike, WELL, the neighbor backed over it, bent the rear wheel and frame, so he took everything back off, came by with a box full of parts and said, "Make me an offer" Being the end of the month, I had NO money, so I borrowed $20 from my pal, Told him its all I got, He said cool, I put everything on a frame I had laying around,so what I had was a $20 bike build. SO, IT CAN BE DONE for far less than $300 if ya get lucky. Just a regular old mountain bike, good brakes, steel frame, solid build. ran great. of course I sold it for $300. Let not discourage the guy by saying he's gotta have a $300 or $400 bike build for it to work. I did it for $20 and an old bike that someone left at my shop. I think if I were him though, I would take EVERYTHING off the bike. Check and grease all the bicycle bearings. Then pop off the jug and check the piston, rings, crank, ect. But that might be going too deep for a noob. I was serious when I said I wish he was closer so he could spend a day or two at my shop learning. He sounds like he's commited and would be a joy to teach. U-tube my brother, just check with us before taking advice from anyone. Just couse its u-tube don't mean its right. but you can learn a lot and its got video to follow along with. a pic is worth,.... well, you know.

[crassius]

I wouldn't swap that stuff to a different bike - it may not survive the move - stick a fork with brakes on that frame & spend your money/energy on a new bike & kit later.

when cleaning, don't get water in the mag.

 

[2door]

Ditto to what fatdaddy said.

With a little time, work and a few bucks in parts this bike could be made into a keeper and one that will give Mike lots of fun and experience. Once we get him running he's going to want to build another one and look how much he will have learned toward doing everything right next time.

Let's concentrate on getting him on the road with the least amount of money involved. We all know it can be done.

Yup! It can be done.

I have no quarrel at all with the experienced builders who desire, and innovate, a higher-quality machine. I even hope to imitate.

But a guy with a handful of tools and a good attitude can squeeze a useful life out of even a $50 junker. And then he can start thinking about a more solid bike.

 

[crassius]

I see so many folks who want custom this, reworked that, this trick paint, and that bizarre front fork, all before they have ever ridden one of these bikes, and with no knowledge about tools, engines, or even bicycles. Almost every one of these folks fail miserably at ever getting anything running.
