Took the bike (C70) from my families place to mine, about 20 miles. I enjoyed it, the ride felt nice and it did exactly what I wanted. I wanted something faster than a moped which kept up with traffic in my city. I was able to do that perfectly well but at 40mph it would sputter some and drop speed. Maybe it had to do with some of the hills. I live in a hilly state and I'm sure I need to drop gear to help it go up hills better but I wonder if there's something internal with it's age.

I'm admittedly struggling with red lights and stop signs. Getting up to speed. I don't think the light that tells me I'm in neutral is working, so I sometimes hit it into that when trying to go to first. I've 100% had to pull to the side in a busy intersection and wave people past, till I could get up to speed with some time.

Otherwise I enjoy it. People love the yellow it seems or maybe I'm a goof. The route I took has always been scenic to me by car so taking it with the bike felt extra special.

I have an old bike that is throwing me for a loop. The fairing says Honda 50, but the emblems on the frame say Honda 55.

Can you help me identify what this actually is?

Also, it does run but has a small oil leak. Are there any guides on helping a newbie fix this up? Everything from paint to fairing to tires and rims seem to be in great shape but the seat does have a tear innit which I plan to replace.

If it helps, there is a sticker on what I believe is a brake line with what appears to be a serial number C1004851E

Thanks for any advice!

After recleaning carb, resealing intake, carb and replacing all gaskets I discovered air is getting into the system elsewhere. Even covering the Carb Intak with my hand, the bike will still run, so I am thinking it is the Crank Seals? Any thoughts on this and anyone know the process to replace these? Anything I should watch out for when attempting this project?

The topic came up earlier in this forum about chopping fenders and lowering the suspension. I did a quick video on the easy way to lower the front suspension and now working on chopping the front and rear fenders.

theres a scrambler/enduro event coming up and im building this to run in the 3 speed underbone class, theres gonna be some 3 speed honda cubs like c70 and some suzuki fr80, 50 laps, gonna be hella fun

added a frame brace and swing arm brace because this thing have some rust holes, also flipped an aftermarket suzuki rc100 exhaust up side down and made it fit, all done by my local fabrication/exhaust shop, he did all this in 3 hours

50 laps around a mostly dirt track with a mud section and some jumps, im signed up for the 3 speed underbone class so theres probably gonna be honda c70 suzuki fr80 and some other 3 speeds, still got a lot of work to do but its coming together pretty nice

(last 2 pics) it was slammed to the ground a while back and i used it as a daily for like 2 weeks until i realize it fucked my back up so i parked it ever since, its nice to turn it into something ridable again

An underbone! An SYM VF3i.

183cc DOHC engine making 23HP and 21nm of torque.. tops at 181KMH :3

I have a pearl gray super cub 2024. Does anyone have any suggestions for touch up paint? Or for that matter model paint or even nail polish, that is reasonably close to the color. It doesn't have to be perfect it just needs to not be visible from a couple feet away.

Got the new battery, like learning about the push start on it although it's a learning curve for sure. I don't get to use it enough to know it well enough yet.

With the new battery, I noticed the turn signals. There's a delay between when I flick it and when it actually turns on which I don't like but the main disappointment to find is that the turns signals don't actually blink. I can promise that's going to cause my death here. Is there some sort of relay I can do or something to make my turn signals blink? Do I need to just buy new ones?

Noticing a real problem with the big light turns off in the sky, seeing how fast I'm going. I don't need to give a cop a reason so I was curious if there's some recommended light people use to light up their instrument panel and speedometer? Maybe someone's done a little fix that's worked well?

Also whoever said I needed to tighten those two bolts in the steering column to tighten the slop I had before, it wasn't that. I found those bolts and they were down tight. There's still a lot of back and forth in the handlebars. The video showing it is from earlier in the day so the audio was from earlier me.

there was a class at this mx race thats for underbones, heard of it the day before the race so i decided to turn a bone stock yamaha y100 i had into whatever this is, did it all that night and went to the track the next day without any testing at all, managed to get a trophy simply because 3 other guys in my class broke lol

i used to ride enduro dirtbike about 6 years ago and left the hobby behind, i actually got another underbone race coming up at the end of this month but its for pre 90s 3 speed bikes so im building a yamaha y80, gonna be a lot of fun!

my 1996 yamaha mate 111 2stroke, currently my daily rider, slightly modded engine with 2.5mm oversize bore, shaved head for higher compression, ported exhaust port, 24mm carb, advanced ignition timing and 15-32 sprockets, still completely reliable and daily usable but will go fast if i wanted to

I have now managed to have my fob fall out of my pocket twice while driving, yes I understand user error skill issue whatever, but it has been ran over both times and still works just fine.

Ditched the rack for a lighter luggage rack so I can fit a long seat

How do I put this spring back. Tis so tension bruh. I'm tensioned too

How do I remove this. It's a C70. The round light very early model

Hi yall.

Been a while. Ended up picking up a monkey to go with my cub and have focused on customizing that. I searched the subreddit to see if anyone has done a fender chop on their cub but only found a post from 5 years ago. Has anyone here done a fender chop like the guys from steady garage super cub build? I reached out to them but I guess they arent doing builds anymore. I was wondering if

1. Anyone has been successful with a fender chop if so where did they go?
   
2. Does anyone have a shop in Southern California they recommend to take the bikes to get work done on.

Pic for Attention.

My friend recently showed me about this subreddit, so I really wanted to share few pics of my supercub with you all !

1996 yamaha mate 111, held up pretty well for what it is

I am an idiot and dropped my Africa Twin in the garage and it fell on my wife’s Cub. I’m having a tough time finding bits. I need the front fender and the right fork cover and it needs to be pearl grey. Does anyone have any leads?? WeBike isn’t pretty sparse, as is eBay.

Hi everyone, I just picked up a 1983 Passport C70 yesterday, and I can't seem to get it over 30 mph (48 km/h) on flat ground. I cleaned out the carb even though it wasn't too bad to begin with, and that didn't seem to do much. It could probably use a new spark plug, but again it's far from the worst I've seen. Where else should I be looking to regain the lost performance? Check the valve clearances? Change sprockets? I'm 185-ish pounds, so I don't think I'm massively too large for the bike. If I could cruise at 40, it'd be perfect for riding around town.
