Ebay scrambler

Saw this late CL77 on ebay: http://cgi.ebay.com/ebaymotors/Honda-CL ... 1c319b716f Aside from the hacksaw mutilation of the pipes it looks pretty good. The seller seems to be quite proud of how well it runs. I watched the two videos of it running, sounds to me like it's only running on one cylinder. He looks pretty young, maybe he hasn't ever actually heard one of these run on two cylinders before.

I agree. Sounds like it is only on one cylinder.

Having a a CL77 that for two years likes to run on one cylinder when it wants to (hopefully I understand why now) I would agree that it is only running on one jug.

I also liked the water;stone scoop on the right front engine case.

Will be fun to see what it goes for in OK.

Well I'm here to hang my head in shame ..

That is one of my bikes. I could tell it wasn't 100%, but my wife (the videographer) wasn't going to sit around while I did anything with it. It puffed some smoke on that startup, and didn't again.

I haven't run it since I got it going about a month ago. My best guess (and something I planned to check this afternoon) is that I have a fouled spark plug on one cylinder. It took me some time and help from Ed Moore to get it tuned (I had my slides swapped), so I think the spark plugs probably need replaced or cleaned because I ran it quite out of tune while idling for a bit. I may be wrong, but that is what I am going to investigate first.

I tuned it then parked it shortly after. I sycned the cylinders to the best of my ability by comparing the flow and temperature of the exhaust on each pipe. Both were definitely hot and flowing about equal then. I'll work on it this evening and post a video later.

It is indeed my first restore on a multi-cylinder bike. I have restored about 20 or so horizontal hondas in the past year, so I definitely still have things to learn. (pictures here if curious http://www.tulsahonda.blogspot.com/p/sold-bikes.html)

This is the bike as I bought it BTW

Let me know if this sounds better. Both headers and exhaust are definitely hot. Certainly sounds more fluid a higher RPM.

I cleaned the plugs and made two videos.

Here is one attempt, RPM seemed a little too high.

Played with screws a little more, here is where I left it. Not sure it is better than before

Sounds like you're gaining on it, sounds better. I had one the same color in 1967, only new CL77 I ever owned. I like to sync the throttle cables by pulling the float bowls and the main jet holders, then back both idle stop screws out an equal amount until the slides are bottomed out. With the jet holders out you can touch the ends of the slide needles with the fingers of your left hand. Working the throttle with your right hand, you can feel if both slides move off the bottom at the same time. Once the cables are lifting the slides at the same time, run the idle stop screws back in and put the bowls back on. Adjust the air screws in or out to get the best off-idle response, consistent with a smooth idle.

Yup, sounds better.

And well done on fessing up. My dad taught me at an early age that it takes a man to admit he's wrong.

If you want to make it sound a bit better without braking the bank, put a pair of Emgo shorty mufflers on it. It won't be quiet, but it won't be so raspy, either.

Nice job on bringing her back from a pretty tattered condition.
