I picked these up back in August and I think I'm gonna start workin on them this weekend.

Honda CL70

Good: Well it is there. LOL A lot more stuff on ebay for them. Found some websites that sell parts, tires and modified engines. Already bought new carb.

Bad: I hope the forks aren't rusted up. Needs new cables, pretty much anything made of rubber (ex: gas tank pads, tires), needs chain, some wires need to be redone, needs battery, engine condition unknown.

Yamaha YG1

Good: I can feel the piston move with the kick start. Clutch cable works.

Bad: Pretty much the same as the Honda. This is why you dont leave things out in the open. Bent handle bar

The Honda is a 4 stroke and the Yammy is a 2 stroke with oiler. I plan on working on the Honda first cause my other bike is a Honda. LOL I want to have at least one engine running in a month.

I have to clear out some stuff in the garage like tires and a cherry picker. Those seem to take up a lot of space. :lol2:

My first of my own was a green '71 model. Paid 50 bucks for it and it was sold a few more times for 50 bucks each time. It just kept on runing.

Where are you finding these? I have looked all around for a 70 or a passport to bring back from the dead. Seems most have been cremated.

Got them from a lady when we were working on her house. She says she kept meaning to scrap them.


The piston on the YG1 actually moves so hopefully with a few wires being replaced I'm hoping she'll start.

Now the Honda didnt have the carb attached so I'm fearing the worst.

I need to find out what years they are. I know the honda is a K1 or K2 model. The yammy I just know its early 60's.

Rangerscott
05-09-2009, 10:31 PM
Started working on the CL70. So far so good. I can only test mechanical stuff since the wire harness is a little cut up and I dont have a working 6v battery for it.

Got the piston to move with the kick start and sounds good. Got a list of things I need to order.


I'll upload some pics in a sec.

Rangerscott
05-10-2009, 12:52 AM
Well this is what I got done today. Not much but I know what I need to order for now. Even though the fork boots pretty much fell off and there was a ton of oil/dirt, the tubes look good.


She's so dirty.

Bought a battery, gas tank rubbers, petcock, coil & spark plug cap, and seals for the engine.


If the engine turns up bad I'll just order a performance sleeve and head or maybe even one of those Lifan engines.


I did find out the frame and engine are Cl70K2 models.




Showing the valves moving.

Got the petcock, seals, gas tank rubbers, and spark plug cap. No battery or coil. I'm just gonna see if it'll start without power. Im sure it will.


Still dont know how the petcock installs.

I'm getting a lot of white smoke when revving and under load. She bogs down when I try to take off.

I think she's getting to much fuel but there's only two adjustment screws. One for idle and another I'm guessing is an air needle.

Is there any way to increase the intake air?

Not sure. Trying to find some info on these little carbs.


Gonna check the jet numbers on the new carb to the old carb.

Rangerscott
05-21-2009, 08:38 PM
The stock jets (main & slow) were smaller so I swapped those in. Seemed to help some but she still wants to bog down when under load.


Also checked the timing. Seems to be good.

TWTim

Take the air filter off and see what happens.

Rman of 237
05-22-2009, 09:02 PM
Like Tim said.. pull the filter and see what it does( be sure the engine's warmed up). Next, make sure the pipe isn't clogged up with dirt. Dirt Daubers love exhaust pipes! That will make it run rich.

Rangerscott
05-22-2009, 11:43 PM

Does it with filter on or off.

TWTim
05-23-2009, 12:23 AM
Hmm. Then I'd check for exhaust blockage, as Rman suggested.

Also, are you sure your premix doesn't have too much oil in it?

I hope the yammy starts up cause a lot of things are discontinued or expensive.

Patched the tires, lubed the bearings (they were all tight), rode her for awhile. Still gutless but running.


Ride vid tomorrow.

Rangerscott
05-31-2009, 06:54 PM
Still no vid. I was sick all last weekend and the work week kept me worn out. I did get a vid but when I was editing it the program froze and I lost the file so I'll get another vid.



I got another problem now. The carb is leaking fuel out the bottom of the bowl. Its a vent and the tube inside goes way up so the think is just filling up with fuel I'm guessing. It just started this today and has NEVER done it before till now.

Still doesnt wanna run without out choke set some, but doesnt run well. Anything over 1/8 throttle she bogs.

I adjusted the valves but they weren't that loose. Cam chain looks nice.

I turned the intake & carb around to how its suppose to and now when it cranks over it just full revs. I have to turn her off. Adjusting the screws does nothing.

I haven't done anything else from what I've already done. I didn't bend any part of the float. The float needle is seating correctly. I guess I'm gonna have to bend the float tabs so is doesnt fill up so much.



I'll check the timing again tomorrow.

Rangerscott
05-31-2009, 10:00 PM
I think I figured out the rough running and having to have the choke on. The replacement carb I have has a bigger venturi than the stock one. About 4mm or more bigger and its oblong shaped instead of round.

Gonna try the bigger jets that came with it again. May need even a bigger main jet.


Gonna keep my eyes open for a stock carb but it isn't gonna be easy finding one of those.

>> stuck float (tap it), float too high, or needle above float bad

>> main jet problem. Clean out jet gently.

>>agree


I'll check the timing again tomorrow.

I also suggest turning off the petcock when not in use. Did any gas get into the oil during overflow? Replace oil again.

Remember on the idle there is a speed screw and an idle mixture. Set the idle mixture to 1.5 turns then speed screw to proper idle.

Looks like a fun project.

06-01-2009, 11:27 AM
I would also check for an air leak between the carb and the manifold. Let it run and spray the gaps with wd-40 and if the rpm changes, you found a leak. Too much air will cause a high speed bog.

Rangerscott
06-01-2009, 06:45 PM
The carb is new. Everything is clean. I added a filter to the line. Throttle cylinder is operating correctly and so is throttle cable.


The main problem is the venturi is bigger so it changed the air flow. I bought a used carb off a XL and it looks exactly the same as the CL one. There's another on one ebay cheap locally so I'll if the dude will end the auction.


Got a surpise.I'll post pics after I'm done later on.

Haven't done much since I'm getting frustrated that she's not running correctly.

I just got done replacing some seals, draining oil, and replacing the point. Tomorrow I'll replace the condensor and recheck the valve clearances.

I'm still waiting on some oem parts which include some spark plugs. So that would be nice if they showed up tomorrow.

Good luck with the engine.

Rangerscott
06-09-2009, 06:29 PM
I just cant get her running right and she smokes so gonna start taking the engine apart and see what needs to be done.

I have to see certain parts of the insides to know if I can bore the engine (short rod, is it this or that, etc) and I may order a new head with bigger valves/cam. Just gonna start new and hope she runs right then.



Putting windows in a church in a small town and wouldnt know. 500ft away is a Honda CL70 sitting on a porch. LOL Gonna ask tomorrow if they want to get rid of it.



I need to slow down some on her cause I'm getting burnt out. Won a new honda manual for it (new as in printed in this decade :lol2: ) and should have the engine fully apart this weekend.

Not gonna order any engine parts until I have everything apart for inspection.

My ghetto valve spring compressor. Big C-clamp and a 3/4" female threaded copper fitting. I cut a section out of the solder on part and grind down the socket edges. I used this on my vehicle engine rebuild. I had to grind it cause it was a tight fit.

Sorry guys for leaving ya'll out on the clothes line. Finally ordered a new head, piston w/rings, and had the bore honed.



Here's the new head with dual bearing cam. I think my CC's is gonna drop cause the cut out is smaller than the original (if you cant tell then look at how close the valves are).

Now I can see that they did valve work once but I'm not sure if the piston bore has been touch but both old and new piston fit kinda loosely in the bore. The old one was nice fit with the rings so maybe thats how its posed to be since it's air cooled.

Well got pretty much all the engine together but I hit a snag of the valve adjustment. The manual calls for .05mm (.002in) for both intake & exhaust. The exhaust valve is setting correctly but the intake rocker has more movement in it so when I set it to .002in, the piston hits the intake valve. So obviously the intake needs to be set different. I know have to figure that out.

I could be but there's no markings. I didn't see anything in the FSM about markings. I'll just have to look again. I just eyeball'd how much the exhaust opens up and matched the intake to it.


The cam is probably different. I just didn't want to take the new head apart.

I'll use "running" loosely now. Still having fuel/air management problems. I have three carbs that are identical to the stock one with everything being the same. From jets to the throttle valve size.

Got it to run ok with an identical carb but it would just keep dieing. I tried the chinese knock off but once it fires up, the engine just revs up. I have to control the throttle with the carb's choke. When I do give it throttle it bogs.

Still having problems with fuel just dumping out of the bowls vent tube. Some times it happens and some times it doesnt. So it must be building up pressure still. I'm going to tap a hole in the top valve cover. (I'll get pics) New petcock stinks just as bad as the original one.


I have the contact point adjusted properly and I know I'm getting spark cause it shocked the poop out of me. New spark plug of course.


Got a new throttle cable coming my way. Still working on getting a new kick starter and gas cap.

Just got done reading all 4 pages, I picked up a 67 CL90 this week, It appear's to be in pretty close to the same shape as your 70, All Ive done so far is ordered a new ignition switch with keys, petcock and honda tank badges, Good compression,clutch feel's good, Throttle is crusty and it has no spark, will need tire's, The list goes on, Your 70 looks good, You've sure put a lot of work into it, Mine has what appears to be a good carb even though fuel is running out the bowl, I had to put fuel to the carb with a shringe due to bad petcock, I plan on doing maybe one thing per weekend to it and hope I can at least get it to fire. Enjoyed your thread. Im sure Ill have some question's coming soon. SZ.

Pulled the carb off the engine and gave it a good cleaning. Also went to my storage and got all the extra parts. Going to get some pinesol and let all the carbs soak in it for a day or so.

Going to check to see if the condesor and coil are still good.

Randakk( the well known Goldwing Guru) boils his in a water, lemon juice , takes an hour or so. He recommends doing it outside. You can use lemon juice from the bottle. It is a mild acid that dissolves the varnish. Check the needle, they vary on taper and should have a number on it. If it won't idle your pilot jets and circuit may be clogged. If you use chemicals do not use carb cleaner, it well eat your nitril parts, use brake cleaner, it evaporates quicker, less harm to the soft parts.

Thanks for the mention.

That's a slight departure from my actual recommendation. I've never recommended lemon juice...only distilled water. Depending on the degree of disassembly, lemon juice (or any acid) poses some risks. With lemon juice, I'm sure the risk is slight.

If you are having overflow out of the carb, then you def have an issue with the bowl overfilling. You need to check that the float height is set right and that the valve that lets fuel in is closing properly. Until this is done, nothing will make the bike run right.

I messed with the floats and needle height for weeks. Fuel would leak out any carb I put on. Even the new aftermarket one. Its like theres pressure building up in the carb and forcing the fuel out. The bowl vent tube goes high up into the upper half of the carb.

I ordered a carb rebuild kit just so I coukd get new gaskets and spare parts. I hope the throttle cable comes in before sunday so I can get too cranking the engine. Once I get the bike in the garage Ill make a walk around vid so you'll know what Im working with. About to head out to the garage and put a multimeter on the coil and condenser.

Got a couple carbs soaking in Pinesol. Pulled the engine and took off the coil w/ condenser. Tested those two but didn't feel as if I was doing it right. Sadly the FSM is more towards the c50. I have a new condenser I can use. I also have a spare OEM main wire harness I'll use. I need to buy some connectors for some of the existing wires. Took off the contact and noticed the two points weren't touching flush so I bent the top half till it did. Hope that makes a better electrical transfer.

The throttle cable came in today. Hope it's the right length unlike the last one I bought.

It's been sitting for awhile but the oil still looks new (I'll flush anyways), the head is still clean inside, and the pistons moves with ease. Going change out some of the crappy phillips/slotted screws with some allen keyed screws. Dang things are so soft. One important thing I have to fix is the teeth on the kicker starter spindle. I'm hoping I can just use my dremel and the new kicker starter will slide right on and hold.

Another nother problem I have is with the new head. The dang set nuts on the rocker arms wont stay tight which makes the set screw vibrate loose which makes the valves not open much. I think I can get some tiny lock washer that'll fit.

Didn't get too much done this weekend. Been getting myself worked up over this so I just sat on my butt to calm myself.

Made sure the cam and cam gear was aligned properly. Adjusted the valves and set the timing. Installed a new kicker starter and a new condenser.

All the connectors on the wire harness are oxidized or whatever. Some connectors are single round male to single female round and there are also double round females and two male rounds connect to them. I am going to cut all of those connectors off and solder on some new flat male/female connectors. Where there are the double round females I'm going to cut the wire, then solder two wires on to the one to make a "Y" with a female connector on each to simulate the one piece double round female connector.


I let two carbs sit in PineSol for a couple days. Seemed to clean them well. I found that this tube was clogged. Not sure if it'll help since even the new carb would do the leaking fuel trick.

The bad news is it's very cold outside right now. Suppose to be in the 20's till Friday. BOOOO! I just got came inside from freezing in the geerodge.

The good news is the garage doesnt smell like pinesol and I've been saving on my insurance.


Instead of cleaning up all the old connections, I just got to hacking and slashing. Got some connectors and a soldering iron. I have about 10 minutes of soldering experience so it's always an adventure with me. :lol The bad is the rubber around the wire melts/goos when I'm done. Guess I'll pull the rubber away as far as possible, then push it back when done soldering.

Got most of the main lines done expect for a couple. I'm not worried about getting the lights done yet.

The knock off carb seems to be doing better. Tooker her for a spin yesterday and I am still having the bogging problem. I can get it to go with just barely any throttle but any more and it just bogs down. Im guessing bigger main jet? I started with a stock 75 and went to an 88. I guess it helped some.

Going to adjust the needle clip so the needle opens more. If that doesnt help then I have a spare 75 jet thatll I'll drill out.

Dusted her off and she started the first kick. She idles and ai can use about 5-10% throttle then he bogs. If put my fingers in front of the throat I can feel gas.

Changed jets adjusted float, doesnt matter.

Any ideas?

Have you tested the floats for a leak? That could cause your problem, I think.. If they filled with gas, it would cause the problem.

Ive used two used and a new one. When pulled they felt and sounded empty.

Got a deal on a chinese 125cc pitbike. Put that engine in and have been riding it around a bit. The stock sprockets were 13/47 and I could hit 27mph. Put on a 15 front and hit 37mph, then swapped out the rear to a 39 and I hit 55mph!!! Talk about fast on such a small bike. I'd like to at least be able to hold 60mph in a good head wind but I'm probably gonna need a 146cc kit or a 150cc and up engine.

I need to get all the electrical stuff back together. I think I'm gonna go 12v since I hate having to find and pay the price for 6v bulbs, but then I have to figure out what 12v bulbs replace the stock 6v ones.

I would suggest that you look at Beatrice or DrAtv.com. They have a lot of info and parts for the kind of swap you just did. They have the 12v bulbs and blinkers 12v LEDs too.

I think the 140cc engine swaps will give you the 60 mph you want but you still have a frame and brakes that want to stop 45 mph.

There is no logical reason why that Honda motor can not be made to run as new. I hate to see folks toss an original Honda motor and replace it with a Chinese motor of poor quality. Please, please give the real Honda another chance......:rider:

I took the honda engine so it'll stay original and if I ever sell this, I'll swap it back in.

Swapping engines only takes a few minutes. I like the gear ratio on the honda engine but 70cc isnt cutting the butta for me. The chinese engines are just fine. Just take care of it and it'll last. I live a good 20 minutes from work and that's going 70-75mph. I would love to ride this to work and back, the only problem is there is really only two ways to get to work. Stay on the access road on the interstate (have to get on one time to cross over R/R) or go a back road that'll take a lot longer to get to work.

I'm gonna keep farting around with the 125cc till I find a good deal on a 140cc or bigger engine. I really don't want to do a big bore kit on this engine as I got it used and don't want to put a bunch of money into it and have the bottom end go out on me.


Also, yours is in 1000x better condition than mine.

Guess I could install this. Of course I'm sure I have a small valve head and I'm looking for top end speed.

Says it works on 125cc cases without boring it out. Only thing is, I'll have to take the engine apart to figure out my stroke and wrist pin size. I'm sure it's what is needed but sure make sure anyways.

This is the model pit bike the engine came out of.

$1050, and no warranty? :eek2:

That bike was not intended nor designed for 75 mph on the freeway.
The drum brakes are marginal on a good day.
Not trying to bust yer chops, just sayin......

Not plannikg on 75. You should get on youtube and see how fast people get their CT's up to.

Decided to sell the bike I'm flipping and restore tell CL70.

Got this custom built YX engine to put in her. It's either a 194cc or 186cc depending on stroke. I'd have to pop the head and see but don't really care it's gonna haul either way.
