The swingarm on my 2022 Amigo Rocky lasted about 300 miles before letting go on a hard downshift. This is an update video on the damage and what I did to fix it. #HondaCT70 #CT70clone
I saw that angle just eyeballing the pivot. Looks like I need a Honda swinger to prevent this in the future. Great videos Mike. The engineering to that stock job is that the axle and shocks pull it square 😂 its not a great design.
Hi Mike... that happened to me too (around 2006)... luckily I survived 😆🙏 Thanks to those kind of incidents 😬 I learned a lot about the CT70's mechanics and stuff 😉 Glad you didn't get hurt ✌
Them stock swing arms are definitely junk upgrade to an aluminum swing arm. Bart motor company in Orange county California sells the extended ones as well as the standard size one. I ride the hell out mine. As well as ride it hard. I got a go-kart that I ride wheelies down the street on. But I also have an amigo that's all hopped up you can ride a wheelie all day long. I'm in the process of building the motor on that. But I would recommend you put an aluminum arm on your amigo trail bike. Better quality rear swing arm. Also I noticed my aluminum swing arms are so stiff there is no play when you're getting on the throttle. And I polished my aluminum swing NeverDull as well as my aluminum rims. Look like mirrors. I would most definitely recommend the aluminum they're really not that much$$$. Is well as I also run MIKUNI CARBURETOR. Chinese fake one.
There's an occasional remark, generally speaking, about a grease fitting missing on both clone ct70's you bought Mike. The Honda Swingarm doesn't have one either and by design is stronger than Amigo; did you apply any grease or install a zert? Relieved you weren't hurt!
Maybe it's just me, but that swingarm seems a bit thin for the task. When you drop 200 pounds on one of these little bikes, put a more powerful engine in them, but keep everything basically the same, it seems to me you might have a problem with one of the components failing under the increased stress. My dad was a welder as his occupation. He used to talk about guys putting on tall rear tires to make their car look like a hotrod. He warned that the front end was not "designed" to handle the shift in weight which would cause the front wheel bearings to fail more often. Ever since then I've gotten a bit skeptical of some mods that boost performance. Just something to keep in mind.
I was comparing the swingarm to an older, early model CT70 swingarm. The clones are copies of the 90’s CT70’s, which I’ve never owned one of. I don’t know if the 90’s Honda swingarms are the same as these clones or like the earlier models. But, you’re correct, any part can fail.
Glad you didn't get hurt. We have these chinese clones in europe for years and this is really common. Also the engine mount bolt holes also tend to tear out of the frame. In the first versions many moons ago even the frame twisted under hard breaking. The first time i picked one up i went through my back cause i was expecting more weight. but all and all ones you get the startup problems out of the way and really nice daily.
I bought my first CT70 clone in 2002 and have had 25+ of them, I’m fairly familiar with them. I’ve not had any problems with previous bikes, but will admit that ride this one a little harder than the ones in the past.
The guy at “Tin Roof CycleWorks” installed the Trail Buddy aluminum swing arm on his clone and says it makes a huge improvement to the way his bike handles.
His is also an Amigo. Even after shimming the swing bolt, he shows in his video the rear wheel misaligned to the driven sprocket side when looking at the back of the bike.
You should be able to use either one. The black wire powers the headlight thru the battery. The yellow wire powers the headlight straight from the engine stator.
Metal of the same thickness does not mean its just as strong...the chinese material may be softer or lacking in tensile strength compared to the genuine Honda material.
With the carb, tires and sprocket gearing, I can hit 60 on flat ground…..if there isn’t too strong of a head wind. It runs 53-55mph smoothly and without trouble.
I kept looking at that also and couldn’t decide if it was actually thinner or my eyes just thought it was. If I remember, I’ll take some measurements the next time I’m at the shop.
I’ve never officially checked it. I filled the tank and went on a 43 mile round trip ride recently and had a small amount of fuel left. I think it has a half gallon tank……so maybe 80 to 90mpg? 🤷🏻♂️
Whew! Mike's brother-in-law here. So glad to hear you didn't make my sister a widow! Was this the bike I rode during my summer visit? I remember pulling out of the garage, veering left and almost sideswiping your shiny SUV. Was hoping I could blame this crappy swingarm, and not my crappy riding skills.
Jay!! She can’t get rid of me that easy. Yep, same bike you rode. The issue was definitely in the bike and not your skills. 😃 It was 100% stock when you were here. The few mods I’ve made has turned it into a really fun bike to ride. Come back and we’ll go for a longer spin.
A lot of people, myself included, make the mistake of comparing these clones to the early CT70’s, when they’re actually based on the rereleased versions of the 1990’s. I’ve never owned a 90’s CT70, but it’s my understanding that these bikes are built very similar. I would be curious to see if Honda had changed to this style swingarm and they were just copying it. The other thing to remember is that Honda designed it for a 70cc bike and most of the clones have nearly double that power.
@@MiniBikeMike Yeah I understand that power issue but Im guessing you'll be running that Honda swing arm without any problems. Lets see what happens but from expreriment I must say that on speed, locking wheel is no joke. So its a point in the structure that I would not want to second guess anything. Same goes for the frame. Anyway I was talking chinese bikes in general. I have some experience with eastern scooters and choppers with honda type horizontal engine and those experiments... well lets just say that you get what you pay for. Im sure most people will be fine with them but once you have ridden something else, you certainly know the difference.

glad you was not hurt great video keep them coming
Thanks. Wasn’t that bad, just came to a skidding stop. I’m really glad the chain didn’t bunch up and break the case on the engine.
Hi Mike... that happened to me too (around 2006)... luckily I survived 😆🙏
Thanks to those kind of incidents 😬 I learned a lot about the CT70's mechanics and stuff 😉
Glad you didn't get hurt ✌
Thanks Mario! Same to you. Mine wasn’t too scary, just came skidding to a halt, but bike stayed upright.
on a genuine ct70? Did you figure out what caused it to fail?
@@7un05 in my case it was the rear swingarm bolt, it was worn or maybe it had a very hard previous life 🤔
1978 CT70, the bolt was original 😬
@@marioruiz5313 Dang. That must have had a very hard life indeed! Good that you got to tell the tale! 😬
I installed a stock CT70 swingarm on my clone about a year after getting it. Huge difference.
It sure was for me, also. 👍🏻
Damn!!! Mikey!! Glad youre here to make a video about it 😐😐😆😆
Thanks. It was a little squirrelly, but not too bad.

That video is 16 months old. The bike was fixed along time ago. Probably has 3000 miles on it since that video.
@@MiniBikeMikewow what a comparisons when you had them swing arms side-by-side the Honda one is definitely more stronger and more thicker metal
Honda, there is no substitute.

@@horsewnoname872 There’s no need for grease or a zerk fitting. Nothing on the swingarm spins or rotates on the swingarm bolt.

Ne gusta tener una soy. COSTA RICA
Best Honda advertisement going
Last word in Heroism riding Clones, but any equipment can fail
Glad your ok
Great video

Another reason to get the champion.
Sure am glad that you were not injured, sir. I was about to send you a swing arm lol
Thank!

I have a question about ct70 12v headlight can you use the black wire or the yellow wire
You should be able to use either one. The black wire powers the headlight thru the battery. The yellow wire powers the headlight straight from the engine stator.
@@MiniBikeMike right that's what I thought with the black wire for a running light does the stator charge the battery
I'm running the same carb, for 2 months now. Got the same jets and needle lvl, runs a little rich on mine but plugs are cheap.
I’ll be curious to get more miles on mine, but cold weather has moved in and miles will be scarce for a while.
Metal of the same thickness does not mean its just as strong...the chinese material may be softer or lacking in tensile strength compared to the genuine Honda material.
Can you put in the link for the nibbi carb. Thanks
Nibbi 24mm carb
amzn.to/3WMEdg8
@@MiniBikeMike
Thanks, so air intake has to be larger than 46mm.
@@JMP350 the air inlet on the carb is 24/25mm.
@@MiniBikeMike
I meant air filter. Sore
Sorry
Great video enjoyed it
Thanks Don!
Lucky you didn´t crash!
I think i Will get a aluminium arm for my skyteam clone 😃
Hello, how many cc is the engine of the amigo ct70 clone, thanks.
125cc
Thanks, Great video
You're topping at 60 !?!?
Did I hear that right?
Dang, maybe I need the carb upgrade.
With the carb, tires and sprocket gearing, I can hit 60 on flat ground…..if there isn’t too strong of a head wind. It runs 53-55mph smoothly and without trouble.
It looks like the metal gauge is thinner on the Chinese swingarm which could also contribute to deforming under power?
I kept looking at that also and couldn’t decide if it was actually thinner or my eyes just thought it was. If I remember, I’ll take some measurements the next time I’m at the shop.
any warranty
Not sure, but I doubt it. I’d already modified a few things on the bike, so I’m sure I had already voided any warranty. 🤣🤣
Wow Mike… have you been doing practice runs for the “Isle-of-Man” super-bike race???
Nah, just riding along and enjoying the view. Haha
What kind of gas mileage you getting on new carb great video thanks
I’ve never officially checked it. I filled the tank and went on a 43 mile round trip ride recently and had a small amount of fuel left. I think it has a half gallon tank……so maybe 80 to 90mpg? 🤷🏻♂️

What is the engine cc on this Amigo. Would you recommend that same carb on a stock CT70?
125cc. I’d say it’s too much carb for a 70cc. You’ll want something 16mm to 19mm.
HOLA ne gusta tene
Makings of a disaster. This is my problem with chinese stuff: cost savings on vital materials.

Very cheap China Ct70 clone.
Absolute junk. Literally fall apart sitting in storage
Sounds like you’re kinda new to the Honda mini & clone bikes. Keep watching, hopefully you’ll pick up a few things.
total lost
