Hey guys, just joined. I mainly ride an 07 Suzuki GSXR 600, and i've had a bunch of other bikes. But I've always wanted to get an old CB to do a cafe style build, and I finally found one. I came up on a 73 CB360 in killer shape about a month ago. A buddy in the AF bought it out in Kentucky, and had it shipped out here to SoCal. He never rode it, and it'd been sitting for years. But the thing only has 1700 miles on it! So I picked it up for $300, and started work. Took a deep carb cleaning and a new battery, and I had her fired up, but she backfired like hell. Checked out the points, and turned out the gap was off on one cylinder. Got it all adjusted, and she ran pretty good.

Now I've put new, larger directional tread sport style tires on it (a bitch to get the back tire to fit), rebuilt the carbs (K&L rebuild kits), new shorty mufflers (original left muffler was shot...split right down the seam). New chain, new Uni foam angled filters (original filters were solid mold).

I've got a Old Bike Barn cafe racer kit on order (Clubman bars, grips, shocks, viper fairing). Thats getting it all started, then I'll work on other ideas.

Any tips, questions, comments!??

the start:




torn down for tires:


here she is tonight, after new tires, chain, etc..





Here's how I setup the Uni filters. I used the stock rubber boot off the original filters to get the new ones to clear the battery box:




Yep, 1790 miles!


Front view:



A couple issues I'm having so far:

What do I need to do the carbs to account for the Uni filters and the new mufflers? The bike runs pretty well, but will kind of bog when I give it WOT while cruising. How do I get strong throttle response all through the RPM range? I'm using stock jets right now. How do I adjust the mixture screws on the outside of each carb to run better?

The front disc brake caliper or master cylinder is pretty much shot I believe. When applying the brake, the piston in caliper will go out, but it won't retract. It clamps down on the disc and pretty much freezes the front wheel. I've flushed the front brakes with fresh fluid, and bled the shit out of them, but its still not working. Any ideas?

it's probably lean right now. You've changed the air filters and the exhaust system, so it's probably flowing more air right now.

Bigger main jets, maybe raise the needles. Have you looked at the plugs? Do you know how to check plugs for rich/lean? CHeck this first, you don't want to burn up pistons!

as far as the front brake goes, you should disassemble the caliper and piston. Those pistons corrode, and the seals degrade, and then the calipers stick. You might be able to get away with just a cleaning and a caliper rebuild kit (they're not expensive). If the piston is badly corroded, you'll need to replace it.

Hey guys, thanks for all the replies. I didn't realize I had so many. Is there any way to set this forum to notify me via email that there are replies to threads I'm involved in?

Anyways, I do know vaguely about checking the plugs for color to determine rich/lean condition. I will give it a shot later this week. It does run pretty well but I'd like to get the carbs dialed in correctly.

As for those mufflers, they are made by Emgo, I'll get the part number and post it for you later tonight, I've gotta find the box. I just went with them b/c they are cheap ($16 each). I ordered them from my local bike shop. They sound decent, but they really have almost no baffling and are pretty loud. They're just temporary until I try and track down a decent alternative for the bike. You can get them at JC Whitney too, check this link:

And thanks for that link to the CB360 on ebay, damn that thing was clean! I can't believe it sold for that much! Mine is not quite as clean, but has less miles on it. It was definitely not stored as well as that one was though.

I'll keep everybody updated, been really busy with work this week and haven't made any progress.

those shorty pipes are also available as universal exhaust from
www.oldbikebarn.com should be a first stop for alot of bike parts.
You need to get a seat @ http://caferacingparts.com/ bret is a member here and has good seats and fairings and his fairings come with windscreens.But you should get a seat and sell that big fat and heavey seat to a purest.Also the rear fender unbolts half way done to clean up the tail end when you fit the seat so you can show more bad ass tire.www.backallycustoms.com the red frame bike is a cb360 I built the seat from metal and used a tank from the cx 550.The black From War Horse (cb 450 ) is a twin I used the cx550 tank again,used the cb360 petcock .Both bikes came out looking very expensive and I spend next to nothing on them.the cb 360 was a frineds bike I built for him.

Im so far behind ,that I think Im in first.

Im building another cb360 a 74,its the same with black painted frame,cx500 gas tank and I opted for a glass seat upholstered.I painted the seat and the tank black with thick silver stripe down the center.Yeah I love the look of that cx500 tank its big and breadboxy and just needs a thin strip of metal, either welded or riveted to the "C" shaped mount, on both sides of the tank, to make it work in the front. In the back I have a single bolt,found suitable rubber grommets at a hard ware store to fit on the bolt both sides of the tank to keep it rubber mounted , holding it to the frame thru the seat.you have to be creative in the rear mount to make it work but its a no brainer.
