Not much happening with the CL77. I’ll winch it up to put the exhaust on



I do other projects most are documented somewhere some aren’t. This is one.



I was looking for my next project and had this idea. Supercharged Nos Postie bike. Say that with out smiling. I can do this don’t know what I’m doing but have enough skills to get me where I’m going.

So I bough a pile of parts and made it. The story is documented on my YouTube channel “tioli bikes”
This is the result enjoy I did





This is going to have layers



It’s just coming together so nice every think I like to do is hear and we are moving forward.

Had a look at the Video.

Thanks whitehillbilly

It’s a shame is some ways you make these things play them for awhile then look at them for a while and it’s time for them to go. We will see where this one goes if it does.

I think all of us have a list of bikes we wish we still had.

Rear hub before





Deglazed the front pads and put them on the back









This is where it’s going to rest for a bit.



Thank you for looking, I hope 2025 is a good year for you. See you on the other side.
Another crush wants my attention

Thanks for Posting.
Looking forward to hearing it run in 2025.
Have a good break, what every you get up to.
Greeves now registered and on Historic plates, so some riding for me.

Time to put the exhaust on. The exhaust is the reason I put the side stand on the other side. Hondas first scrambler exhaust.



Side covers go on next

This is before take a good look at its general demena then after and I think they are the same just refreshed and ready to go on.



That’s a win



This two will get vintage plates and occasional club rides so I don’t want to retain a battery so see if a capacitor works.

It runs, smoky has a tick and revs slowly.

Took it for a run down the street and back. It was healed back like it’s ment to kick in revel it out nothing very dull.

Rode into the shed revid it a bit it idles smooth. Got the pliers out and pulled the left plug off while idling. Put it back on took it off. Nothing doesn’t fire on that side?!

Took the plug out and it was wet. Ran it on one cylinder and with the plug in the cap rested it on the head. It sparks very well kernel is fat enough white with blue hue. Hold the plug away from the head at least five mill and it jumps easily from all over.

So what is it. Runs really well at idle on one. Conclusion that carb is jetted very well and as far as I know a mirror image of the left one. I know carbs and nothing blockers like that. Open the float bowl bung and it runs fuel. So there is fuel in there.

Doesn’t make sense gets fuel because it’s wet but won’t fire in the combustion chamber. Yet the left pipe is the same colour as the right. It’s getting just as hot to colour like that. Hmm this is a tricky one.

I remember getting a tickle while experimenting with the plug and I think I remember it arced through the metal plug cap.

I’m not convinced I need to pull the carb apart and have a hunch

You will have to wait till next time.
What’s your guess?

I think the plug cap is letting the spark find a shorter route. The plug caps are not OEM but I thought they looked period. Got hem off eBay. OEM ones are Grey which aren’t made. There is a OEM equivalent in black but thought I’d try these for the look. Didn’t work.

Seems a bit close?





Thought I’d wrap the lower part of the plug cap with silicon shrink tube should be non conducive? The socket is to give it some thing to round off on.



Didn’t need it I could shrink it to size first.







Didn’t work that well helped but still runs on one mostly.

The plugs are telling a story left is still firing it’s not with out colour. The right is doing all the work with soot (I’d like to give the bike a good run once it’s vintage club registered)

I checked the points and made minor adjustments they are new so I guess it’s possible they moved?

I haven’t put the timing light on it yet.

I couldn’t advance the left points enough to line it up with the “F” mark. It was as much retarded as from the F to II full advanced lines!

Took the new “eBay” points out measured them couldn’t see any obvious difference put the old ones back in and now it works.

Runs on two most of the time. I think the capacitor is not holding enough at low revs which also makes it hard to start and worse when cold. Motor won’t settle easily so the slides may still be a bit sticky.



I put a second layer of tube on which makes no difference and when I do this and bring the tip of the screwdriver in it jumps a spark.

Ordered OEM black caps, new exhaust gaskets as I have to clean the oil off the pipes. Probably need a battery maybe new throttle cable, there are 3 other bikes wanting my attention so I will put it away for now and get back to it shortly.

Took the exhaust off and polished the burnt Penetrol off with soapy water and OOOO silver wool.
I like it.



Mounted the exhaust in a different spot. The muffler mount was a bit bent, middle mount doesn’t want to line up and I forgot to take the old exhaust gasket out.



The motor had this mechanical rattling sound and couldn’t pin where it was coming from. I think it was the exhaust so made sure the gap between the pipes is as OEM as I can make them about 3 to 5mm. I didn’t put enough emphasis on getting the gap right the last time and had it at touching to not.



Didn't like the look of the eBay supposedly period branded replacement caps no longer available in grey now black. looked a bit fake so used the best OEM grey cap with new rubbers on the left side. Best made up black cap on the right.



Got the look



This bike is ten years before my time. I keep my road bike up to date so this is vintage to me.

Hondas first Scrambler, Another adventure.
