Starting a restoration project - Honda CT70 minibike

This will be a slow process, just had my first daughter a month ago and work is busy, but it will be fun.

Going to make this one pretty close to original.

First step will be stripping this thing down to parts. I've got a fairly complete 2nd bike in parts already. Depending on how much good stuff I end up with I may do the second one "custom."

Other than some rust the frame is in great shape from what I can tell so far. I can't see any dents or cracks in the metal.

Very nice! a classic. Should be a fun build.

Does it run now?

Congrats on your daughter.

Tag for updates.

In the 70's, my neighbor, who was probably 50 something at the time, used to ride one of those around locally everywhere when the weather was good. It was champagne colored.

As an elementary schooler, I was jealous.

Seat removed

I took the cover and foam off and there are a couple of cracks in the pan. To weld and reinforce or replace?

ETA: Going to try to make this log as detailed as possible for any first timers out there that want to try something similar. Even a small bike like this can seem like a big job, but just gotta take it one step at a time.

Tag. I had two of them and had a blast circle tracking them in my neighbor's back yard as a kid. I ran nitro in one of them.

My brother and I had one growing up, we rode the crap out of that thing and it never missed a beat. Good luck OP!

I had a Honda Mini-Trail like the one in the pic as a early teen. It was very tough/quiet and would go places you would not think it would. That thing was great to groundhog hunt with. The seat height made a perfect rifle rest.

Dad made me a slip-on wood/rubber pad for the kick stand that allowed me to use it without it sinking into the ground.

Good luck with your project. Well worth doing.

I had one of those as a kid. I carried around Phillips head shaped burn scars on my leg for a long time due to riding in shorts during the summer months.

I rode one that looked like that only it was red/maroon, if I recall. It was a fun bike to ride arOund the yard and on the easy trails in my area. Funny thing is, I can't remember if it was mine or my neighbor's. We both had a bunch of mini bikes back in the 70's. My memories are getting fuzzy.

I had one of these as well. I'd love to find one and restore it for my kids to learn on. It was a fun bike to ride and learn about maintenance/repair with...

I got one just like this for Christmas in 1970.

In 1973 I moved up to this..

Nice project OP. Been looking for one of those or a CT90/110 to restore.

I used to be huge into minitrails.

The 69 is stock but the 71 has a SL70 H 4 speed motor with a 88 big bore kit, cam, carb, and exhaust.

The 71 had been clocked at 53 mph.

I also used to have a 1999 Chrome Gorilla but I sold it.
The other bike is a 1986 Chrome x-mas special, there were only 2 per dealer.

Had one when I was a kid. Good luck on the project.

I want every bike in this thread.

Somewhere, I have a pic of my buddy cruising down 1604 with his CT70 bungee corded onto the luggage rack of his Fiat Spider. He was the coolest guy I ever knew.

I wish I still had my fathers old Honda 90 trail bike, that is me on the right calling next.

Posted: 7/7/2014 7:23:07 AM EDT

[#23]

Cool! Looks like a fun project.

My brother had one when we were kids in the mid-'70s. I was too young at the time so that's why I'm just standing there.

Nice! The first bike I ever rode was a copper colored Trail 70. I drove it right in to a log housing a bee's nest. Had to retrieve it with a bit of rope and a friend's three wheeler.

That's awesome. I had one of these when I was 4.

I had to use the picnic table seat to put my foot down to stop.

True story. I rode the bike around my house and always went clockwise. To this day it still bothers me to turn left.

Monkey bike!

I had a swingarm Honda 50 foldup bike that it would seem wasn't made till 1973. I had it in 1969 or 70.

I cn't find anything about these on the web.

A fold up 70 would be a great Boat Bike. It is a long walk from the Beer Store in Leamington Ontario to the Marina with a Box o' Beer,

Well, power went out at my house after work for about 4 hours yesterday, so no updates for this morning. Tough to do work in the dark, especially when it's raining outside.

Cool project OP. Ihad one of those when I was a kid. They are a blast to ride

Made some progress last night. Here's some pics of tear down progress and all the extra parts I've got. Almost 2 complete bikes worth.

Well I must have just stepped out of the Matrix. When I was a little kid my neighbor got a Honda 50 for Christmas exactly like yours. Then when he got older he got a purple Yamaha 100 just like yours. Tell me your name is Gary McCullough or I'm gonna have to try and puke up this red pill that must be in me.

I shit you not, I scored an LT3 like that for 50 Dollars at a barn sale a few years back. I got it running with a through carb cleaning, tank cleaning, a new ignition coil, and a spark plug. I took it for a dig down to the mailbox this morning

Thanks. lilhonda.com is good too.

Started paint removal on the frame yesterday and found some problems where the engine bolts up. There are a couple of reinforcement tabs that are broken and the un-reinforced holes are egged out a little bit. Looks like I'll be doing some welding.

Will post some pics when I return from my trip this weekend.

Also need to upgrade my sand blaster.
