'74 CB 360 Cafe Build - Luna - "Done"!

[adventurco]

Re: '74 CB 360 Cafe Build! (the beginning)

You need my rearsets. The 360 set has a custom pivot made that makes use of the stock brake rod, return spring, and light switch. 100% bolt on, no mods to the bike required. Or, you can kink a rod up and run it straight from the lever to the drum.

Problem with that is I've gone and hacked off the stock brake rod mounts.

I am looking at running a shortened rod with spring position relocated but worried about "bump brake."

Will post some diagrams after coffee

Alright. Here's where I start getting back into the frame. I've been sucked into cleaning painting and rebuilding that motor for WAY longer than expected. But I think it went pretty smooth for my first time, and the NEXT time I'll be much smarter about it.

So for brake linkage, if I go with a modified version of the rod, I want to avoid bends since it will just flex and reduce the braking pressure. My first two mockups involve modifying the stock shaft to relocate the spring to the engine side of the brake lever arm (as it is in stock position) to absorb movement from bumps.

First mockup, straight from the top of the rearsets (ignore the position of the rearsets, they're hanging). Angle looks pretty awful, and the linkage is going into the brake cam arm at about a 15 degree angle. This one is crumpled up and in the trash already.


Second mockup. Swap mounting point on rearsets so its on the bottom. Angle of rod looks much better. Would do the same shortening and moving spring.

Third mockup. Cable driven brake system. Think this is my best bet. Cable stays will be mounted at the red dots on the image, one on the frame above rearsets and one on the swingarm just in front of rear axle. I think this will give it a big enough loop to allow for little to no movement when riding over bumps, as well as sufficient braking leverage.

Let the schooling begin :

The cable set up will be best even though it isn't the easiest.
I know a lot of people will disagree with me but pesonally I don't like flipping the operating lever on brake plate (various mechanical and aesthetic reasons.)
I know a LOT of people do it but I know why it's a bad idea.
I can't explain it without diagrams and a shitload of typing though (and even with diagrams it gets confusing, either you understand right away or probably never will ;D )
You can move the operating arm a couple of splines on brake plate to get cable entry at a better angle just be sure to check operating arm doesn't contact axle spacer before brake is fully applied

Re: '74 CB 360 Cafe Build! (the beginning)

Thanks pj...and I'll just take your word for it, the stuff is designed to be installed a particular way for a reason.

Trying to figure out where to source cable stays for something this heavy. I'm thinking of using my old clutch cable and shortening/soldering the old end back on with electricians solder.

I saw someone else here (I think?) sourced cable stays from a smaller bike's clutch cable. Hmm...to eBay I go

Meanwhile... In the other garage...

Shift rod linkage has to come out to replace a worn bushing (inside the tunnel). Hoping the mount is still good, it'll be a bitch to get in there and weld a new one.

Re: '74 CB 360 Cafe Build! (the beginning)

I welded a stay I built in to my frame on my 500, and made one for the rod that runs back for the rear. Fairly simple to do.

Re: '74 CB 360 Cafe Build! (the beginning)

Slick. I like the location on the brake stay. Gives it a better angle to connect to the brake lever.
How'd you make the stays? One at the foot peg looks like a couple bent pieces of sheet steel?

'64?

'64?

Yes sir. My pops and I restored it, finished last summer.

My first car was a '63. Miss it.

Re: '74 CB 360 - GLASSSSSSSSSSSSSSSSS

Had a delayed shipment for an install today at work, that means fiberglass time.

Carved up a rough seat pan with some aircraft foam. Couple layers of glass and some ultralight filler on top to smooth it out. I will either be melting the foam out from underneath and reinforcing it from the backside or using it to cast a mold and make some design improvements. To be honest, if it holds up I'll just keep it for now so I can get this damn thing on the road before it snows again.

Added some reinforcement strips at potential weak spots.

Ran down the marine store to pick up some hardener, came back and 2 squirts later I realize I'm out of resin. Just have to make do for now. Barely got a coat of filler on with the epoxy I had left.

Looks pretty rough. Needs some massaging.

Cut out and top coated the rear fender I glassed up last week. Looking pretty smoove:

AND finally...been effin' around with the knee dents on the tank for a while now. Finally got them fairly smooth and hit the tank with a coat of primer.

Time to chill.

The Honda SL350 had a cable operated rear brake from the factory. You may be able to source parts from it.

Nice, thanks for that info. That linkage looks perfect. Going to lash up some cable stays and get a cable measurement, if I'm lucky it will fit for my use.

I would use a front brake cable as it should have a threaded adjuster, particularly CL/CB 350/360
There are also plenty of ATV's with cable rear brake.
I bought a Suzuki T305/250 brake cable, around $20.00
I really like Beetles, had some great times at 'Bug Jam' and other rallies in the 80's (in Britain)

Re: '74 CB 360 Cafe Build - Boomerang

Some of the front brake cables also have a built in brake switch.

Oh I like that. Less shit to stick on the frame (r brake switch). Thanks for the info guys.

Seen some pretty good rally cars out of the old beetles, classic car rallies in Sweden & Northern Europe. Those and the old euro ford escorts, legendary

Found this on eBay, did you use a front or rear cable for the t305? The threaded adjuster is nice and long but worried about the overall length.

http://pages.ebay.com/link/?nav=item.view&alt=web&id=201341190292

Dunno if that link will work. eBay being ridiculous. But it's a stock t305 rear cable.

Also found these: http://www.amazon.com/gp/aw/d/B000WJGQL6/ref=pd_aw_sim_263_1?refRID=0KJYG643TH7K33S6AHGT

I would really like to get something with threads on either end so I can secure the jacket to cable stays, but if it's not a concern at the pedal side I was going to use an old cable clamp from the starter motor wire and make it work.

Re: '74 CB 360 Cafe Build - Boomerang

Check with dealer, the genuine part may be cheaper than eBay. that's a hell of a jump since I got mine
BTW, I got rear cable

Re: '74 CB 360 Cafe Build - Boomerang

I went with a lash up like your first drawing on my 360. It works really well.

I love the bug. We raced a '63 on a '61 pan with a 2275cc motor and a bus tranny, plus we had a stock '63 that we called our parts getter. It had over 400,000 miles on it. We also had a '65 baja that was a killer mud bogger. I miss those days. The wife wants a bug, so hopefully we'll get back into them.
