beginning restoration on a CT70 - not sure where to start

I moved in with a friend who had a CT70 sitting out in his backyard. A relative of theirs some time ago disassembled it for some reason and had a few too many beers while doing so. The parts are no longer anywhere that we know of.

I would like to get this bike working again but I have no experience with bikes (some experience with two-stroke engines) and am daunted by the task. Where should I start with this? Is there a way for me to tell whether it's even possible? The state of the bike is completely unknown to me.

I've attached a bunch of photos including the partially disassembled engine.

You can rebuild it...like the Six Million Dollar Man...better, faster, stronger.
Or you could rebuild it on the reasonably, cheap.

What do you want to build? We can help. All of the parts and information are available.

With the internals exposed to the elements, that engine is going to take alot of love, but you do have a mostly complete bike to start with.

Thanks.

Since it's my friend footing the budget for the rebuild, I suppose I'm aiming for cheap. Although if it could increase the resale price, there may be an argument there as well, since I think that's ultimately the idea (I'm just fixing it so I can ride it).

I've just noticed the stickied resources and links so I guess I'll start with that.

Sand, bugs, leaves, and especially water.
Your bike looks like it's pretty complete, and missing the carb/intake, couple covers on the engine...dipstick.
Not much is really missing, but the stuff that's missing could have allowed a lot of dirt, rust, and bad things to get INSIDE of your engine.

If you're comfortable with it...you'll want to pull the engine and get it on the bench. You'll need to remove the head, cylinder, clutch cover, and the flywheel/stator for a look. Then you may likely have to go deeper, depending on what you find.
You'll need to buy a few specialty tools too...so you don't cause any harm to that good bike.
As you begin to work on it...be careful not to damage ANYTHING. Every nut bolt and part should be treated with care. Most of that stuff is no longer made, or available, from Honda.

Thanks. I'm not sure if I'm comfortable with that but I do have a motorcycle shop which is just down the block from me. Maybe it would be a good idea to bring this bike by and have them look at it? I'm assuming having them do the work on it would quickly dwarf the resale value of the bike

Just be aware if that shop only works on newer bikes they may have no idea about how old school points and condenser ignitions work...you might be way better off mailing that motor to someone who knows them very well like people on this site? It looks like it’s got good bones and most of all the parts are there..if it were mine I would get the motor running, get a new seat ( that red has to go) lol, and install new main frame decals .I’m sure there will be some other small thing like brakes or cables but it would be worth the investment... it would be a great patina bike..remember there only original paint once!!! Most of the old ct70’s I get have 3 different color rattle can paint jobs or dented an scratched and rusted after 50+ years..yours just has the normal candy fade....The carb and intake are not a big deal if you don’t have. Good luck with it!! If you were in Jacksonville Florida I could hook you up being I have multiples of everything that bike needs except maybe an intake.... Haha

Hmm I'll discuss that with my friend who is essentially funding this little endeavor. In the possibility that he says yes, is there someone off the top of your head that would be willing to work on an engine like this?

I'm in Arizona, if that makes a difference.

Just a FYI, building that engine, parts and machine work you are probably looking at close to 800.00+ not including labor. Hope that isn't too much of a buzzkill for your friend.

The bike is relatively complete. I would start a list of the obvious things that need to be replaced. Then go online shopping and total it up, add shipping and go from there. Then see if it’s in the price range your willing to pay? Here are some of the favourite suppliers that I use- DrATV, CHP, PhatMX and others. By looking at the pictures here’s some of the things that I would have on that list.......Seat, decals, carb, intake, pedal rubbers, rear shocks, front fork rebuild kit, chain, sprockets, tires, all cables, brake pads.

Also decide about paint then add that on, then like Old CT mentioned engine work or a replacement engine? Add that on as well.

Then there are always incidental costs and parts that get missed at first add a figure in for that.

HTH

Most Important! Have fun while doing it!
