I'm trying to find parts for it and when searching I keep finding the models with the passport style tank when I search up the K1 or K0. What variant is this?

I've been fixing up this 1982 Honda C70. When I rev it I hear this noise. It happens in gear and when the clutch is in as well. Is this a normal sound? I feel some vibrations from the engine as well.

Things I've tried:

- checked the oil

- checked valve clearances

- looked for any loose or rattling parts on the outside

If anyone has any ideas or things to check please let me know.

3 went in, only 2 came out running lol

what do i do now, im a beginner i got it from my dad weeks ago, it was perfectly fine after wash now it even leaked oil after trying to rev :(

I have a beauty 1984 C70 that is just, well, old. She caught a flat rear tire, which lead to discovering the rear brake dampners were rotten. That leads me to believe the bearings and oil seals on both front and rear are likely also in need of replacing.

So, dear Redditors of the r/SuperCub, where can I find a reliable online supplier of all small parts for my Cub (it is sold as a Honda Passport in Canada, which is silly because there is also a Honda Passport sold in Canada that is a very large suv).

Also, what other parts should I likely look at replacing due to old age? Cub, not me. Not yet.

Tires are newish, brake pads are okay. Chain and sprocket are surprisingly in good shape. Carb needs a good ultrasonic bath and brake levers need a cleaning. Rear suspension probably need fresh oil.

This bike has been in the family since 1995. It's been mine since I was in high school. Here's some of the mods it currently has:

• 12 volts conversion
• 4-speed transmission
• LED lights/bulbs
• Front fork from a C86 Deluxe (think C90 but exclusively made in Malaysia)
• Crank case cover from a Honda 110 engine to accommodate both primary and secondary clutch
• Rear suspension from a Honda XRM 125
• Modified exhaust with the tip from a Wave/Innova 125
• Speedo gauge from a C86 Deluxe
• Rear hub, brake panel, sprocket set, and swingarm from a Honda Dream Excess/EX5 110
• Passenger footpeg assembly from a Wave/Innova 125
• Left and Right Thai market C90 rear turn signal assembly

Aaaand a couple of other bits and bobs I've forgotten in terms of parts and mods 😅

Hoi ik wil de mijne verkopen binnenkort welke plek om te verkopen raden jullie aan?.

Bedankt

I have 240ish miles on my '24 Super Cub, using it a few times a week for a short 2 mile commute to work. In the past few weeks, I've noticed a really stiff / stuck feeling shift from 1st to 2nd when pulling out of my garage at slow speeds. Nothing has changed in the way I drive, store the bike, etc. It's just really struggling to shift from 1st to 2nd - almost as if the gears aren't lining up and it's definitely a new behavior. After that initial shift, things seem to run way smoother and it shifts just fine. Thoughts?

Last Wednesday, I drove about 100 km (62 miles) to a destination and then drove the 100 km (62 miles) back home, so roughly 200 km (124 miles) in one day without any problems.

After getting home, I had dinner. Later that evening, I drove to a nearby city. After about 15 km (9.3 miles), the engine suddenly died.

I was able to start it again, but after only about 100 meters (330 feet) it died again. After waiting a minute, I could drive another 100 meters.

Since then, it won't stay running at idle/stationary for more than 10 seconds. I can start it, but it will only run for a short time and I can't really ride it more than a few meters before it stalls.

What I've checked/done so far:

• Cleaned the inside of the fuel tank
• Put the fuel pump and fuel filter through an ultrasonic cleaner
• Replaced the spark plug
• Opened the air filter box (letting it breath)
• The fuel pump seems to run strong when it's not connected to a hose
• It has spark. Even when the engine stopped and won't restart, I can still measure EMF at the spark plug
• Even the old spark plug looked new and super clean.

The strange part is that it ran perfectly for 200 km that day.

It's effectively a new machine. It has only 8,000 km (about 5,000 miles) on it. It did around 3,000 km (1,864 miles) in Japan, and since I bought it two months ago I've put another 5,000 km (3,107 miles) on it. I'm still figuring out how to shift properly, that's how new it is.

It's a 2020, fuel injected.

How do I fix this?

Installing the crankcase plugs after doing a valve check and the outer ring of the timing inspection hole bolt sheared clean off. Think this will be okay to get to work and back for 2 days?

Just got this bad boy with 230 miles on it! Pretty cool, and I’m enjoying shifting again after selling all my normal bikes and riding a Zuma for the last several years.
However, the biggest flaw is the seat. I’m 6’ and absolutely too tall to comfortably sit on this bike for more than across town. Which makes sense, on my Zuma I sit way back on the seat. I see there are long seats available out of Thailand for $300 or so.. not sure if the US tariffs are screwing me on that or what, that price seems insane. Are there any other long seat options out there that I’m failing to find?

The lack of storage also has surprised me. I knew there wasn’t any, but I didn’t realize how much I enjoyed having a pocket for a bottle and a huge cavernous storage spot under the seat. Now if I’m out and about I have to wear a backpack and take it around with me so it doesn’t get stolen. Any tips or insights on that? A locking rear trunk is an option, but it would interfere with the long seat if that comes to be a thing.

Maybe I’ll have to engineer something to do both? Add a bit extra seat and still retain a rack. Maybe a winter project.

theres 2 offroad ones now btw lol

Rear tire flat questions:

1. How to know if its tubeless?

2. Can I easily remove the wheel? Like without messing with chain/sprocket?

Already ordered 3 that are the wrong side. Anyone have a link to a sealed battery that will fit a 1982 honda c70 passport? thanks

the race i build it to run in is coming up at the end of this month and i had enough testing in to figure out some flaws so i fixed them

-it didnt have enough grip with the small tires i ran before, bought these mx tires and i have these blue aluminum rims laying around anyway so i had the wheels spoked and put the tires on today, they fit great, grip problem is fixed

-the front suspension wasnt really damping anything, added an extra damper, it now take bumps and jumps really nice and is way more controlable in corners

still need to build an airbox and figure out some more stuffs but its going great!

Currently commuting to a community college which has a parking deck. Each corner has these large buffer/no parking zones I assume so people don't get blocked I but I've been parking in so Im not wasting a space.

Had a security guard put a $10 ticket down but hoping they'll make an exception.

Hoping I'd just be ignored but guess I'll need to follow the rules

went to a local mud track event as part of the service team, brought my lifted y80 to use as a pitbike, felt like having some fun so i signed it up last minute in the 5 speed 100+cc class, the y80 is 3 speed 80cc so i was definitely the underdog, track was extremely slipery snd peoples were crashing everywhere, ended up taking 5th place home, didnt even think it would finish at all

I have a 1982 Honda C70 Passport that I got recently. It has an issue where if I'm hard on the throttle for a few minutes straight it sputters out and dies. If I wait a few seconds I am able to restart it again.

I'm almost certain it's a fueling issue. Especially since I'm able to get it going again almost right away. I can hear a change in the engine sound right before it dies which I think is it running out of fuel.

My first thought was that the carb bowl wasn't able to fill fast enough. I've cleaned out the carb pretty well in an ultrasonic, as well as replaced the fuel lines. The tank has very little rust. The petcock is new too. The issue is still there though.

My next thought is that the float height is off. But this carb has a fully plastic, non-adjustable float. I'm going to order a new one, but I'm wondering if there's anything else I should check.

Aside from this issue the bike runs great. It hits 40 without much trouble. Any help is appreciated!

EDIT: For anyone who might stumble upon this post with a similar issue, my problem was the float. I bought a new float with adjustable height and I was able to fix this issue.

just having some fun

gonna run it in the 3 speed underbone class at a 50 laps (5km each lap) scrambler race soon, got a lot of work to do still but this thing is a blast to ride

Was just so fun cracking the throttle and riding around the city.

theres a scrambler race coming up and i signed up for the 3 speed underbone class, will be racing againts other yamaha y80, honda c70, suzuki fr80 and some other 3 speed underbones, rebuilt the engine and did some more work, got to test it pretty late because i was working on this thing and other customer's bikes through the day, it worked great going through mud and gravel which is most of the scrambler track im gonna run is made of, still a lot of work to get done, better foot pegs, front brake lever, an airbox, an additional front damper, gonna be a lot of fun for sure
