Honda CB350

Engine: cc SOHC transverse-mounted inline four, 47mm x 50mm bore and stroke, 9. Magicians like David Copperfield and Criss Angel stun and amaze audiences with their mind-bending stunts and tricks. And while they started big, Honda still had a couple of other tricks up its corporate sleeve. Two years later, inHonda introduced the smaller CB Four. In the spring ofHonda introduced the CBF. So the release of the Four was almost a natural progression — a statement as to what Honda engineers could do. Honda had, of course, been developing the multi-cylinder power plant over many years, with experience gained in both their motorcycle racing exploits and their efforts with V Grand Prix formula racing cars. In the Honda CB Four, this meant a transversely mounted four-cylinder engine featuring a chain-driven single overhead camshaft. Crankcases were of the clamshell type, split horizontally to allow easy assembly of the unit-construction gearbox and the five-plain bearing crankshaft. Primary drive was by chain, taken from the center of the crank to an inboard-mounted clutch. The Four engine is undersquare, meaning the 50mm stroke is longer than the 47mm diameter of the bore. And at 47mm, each of the four pistons is not much larger than a medium-sized plastic pill canister you get from the pharmacy. The multi-cylinder power plant resides inside a single-downtube steel cradle frame featuring dual shocks acting on a traditional swingarm at the rear. Hydraulically dampened telescopic forks hold an inch wheel and a single inch mm disc between the legs. Rear wheel diameter is the same as the front, and the rim is laced to a hub with a 6-inch mm drum brake. All bodywork including the tank, side covers and fork covers is painted, while front and rear fenders are chrome plated. One of the most distinctive features of the early Honda four-cylinder motorcycles was the four-into-four exhaust system. With its four header pipes dumping into four pleasingly- shaped conical mufflers, the bike looks stunning from both profile and rear views. But that exhaust system, and specifically the mufflers, was quick to rot away. Doug has been interested in Hondas since his university days when he rode a 90cc CA around the Penn State campus. After he sold that bike, he rode a Honda XL for about 10 years. And because it was in such superb condition, Doug decided to detail it and kept the Honda as a showpiece. Period after market slip-on mufflers converting the exhaust into a four-into-two system could be had for far less than that. The CB Four featured here was discovered in the Milwaukee area. The story is that the eBay seller purchased the Honda from the original owner, with the intention of flipping the bike. While the machine was indeed a low-mileage motorcycle, it unfortunately had the ubiquitous four-into-two exhaust system installed. He got the bike running, dialing in the carbs before riding it around the block several times.

Honda CB350 / CL350 / SL350 Frequently Asked Questions

Hey everyone, I just bought a CBF and I had a question, the carbs have fuel lines coming out of the bottom and going down under the frame. When I start the engine, they leak out gas. Does anyone know why this would be done that way? I have an ambitious 72 cb project for sale. Engine turns over, tank is decent inside but terrible outside. Complete bike minus fork lower covers and has extended fork tubes installed. Comes with a useable set of mufflers and a 71 frame with Ontario ownership. Has a key aswell. Located in Niagara Falls Ontario Canada. You know that bubbling ultrasonic foot bath the little lady has stashed away in the linen closet that she never uses since the day she brought it home Hey all, is there anywhere a list of basic things to check, or known to "just go ahead and service before you try starting it" on a barn find? Like would you all assume cleaning carbs, air filter, oil filter, new tires, as a given What about timing chain, new points, brake pads? What other things would you just go for on a new-to-you old bike? Is there a list, or flow chart, etc? I'm not enough of a mechanic to just dive in. I need to do things in logical bite-sized pieces with plently of You-tube support. But there must be a rational order of operations to diagnose and service an old bike. I'm sure you dont just put gas in it and kick, and see what happens Bridgestone tires, and the tread pattern was the same on both the front and rear tires. Jump to. Sections of this page.

Honda Cb 350 For Sale

Whether it is good or bad is debatable and many of the sports singles like the Gold Star BSA and Velo Viper Clubman had just as good performance as this new high-rewer from Japan … but there the similarity ends! Flashing indicators, electric starting, wing mirrors, twin-leading-shoe front brake and even minor items like steering locks, locking helmet holder and dual seat are typical of the advance in specification of modern machines. Technically, the CB is almost identical to its smaller brother the CB, sharing the same stroke of In practically all other aspects the machines are identical except in colour scheme. They even suffer the same small 2. Gearbox ratios are the same too, although the final drive ratio of the is higher using a 2. This gives a very slightly higher top speed without detracting anything from the acceleration. The bike we had on test was brand spanking new and we had to take it reasonably easy until at least miles were showing on the very readable instruments. Starting, with the electric starter, was of course simplicity itself. The routine when cold was simply to turn on ignition, fuel and close the choke on the twin Keihin carburettors. A very slight whiff of throttle and press the starter button on the right-hand twistgrip. A few minutes to warm up and then the choke could be turned fully off and with a light pull on the silky smooth clutch, the first gear could be engaged. There was a slight clunk when cold due to clutch drag, but this disappeared when warm. But using all this performance created more exhaust noise than necessary about town. In fact, this is one point where the At small throttle openings, you could hear little more than the rustling of the overhead cam valve gear, but on full throttle the exhaust really started to bark. In fact, the clutch is so light that it is no real effort to use it all the time when changing up and down the gears. Acceleration over the standing quarter mile was Obviously, by changing the gearing with a larger gearbox or smaller rear wheel sprocket on the back, maximum speed could be improved considerably without doing any further tuning to the motor. The question of course is will the handling and brakes take it? The answer! One of the marvellous things about the Honda, in spite of being thrashed without mercy, was that the motor showed absolutely no signs of oil leaks on the outside. It finished the test as clean as when it started. Braking on the CB was just adequate. It was neither brilliant nor poor because although the twin-leading-shoe brake was very progressive and predictable for speeds up to about 70 mph, it did lack power when used to the full from plus and would fade with repeated high-speed stops. What, then, is the general feeling about the Honda CB among the staff of MCM who have ridden it day in and day out over the past few weeks? Firstly, it is very much a dual-purpose machine, equally at home squeezing quietly through traffic jams in London or taking the occasional mile motorway or main-road trip in its stride with one or two on board. Slight criticisms on braking and high-speed handling with a minor complaint about the buzzing vibration felt by pillion riders. Fuel consumption varied from reasonable to extremely good, especially for awhere most of the modern two-strokes really start to become thirsty. It is obvious that with very little effort this machine could be turned into a high performer but the biggest question of all is: who wants a ? The electrics on the Honda are 12v and extremely good. The lights are controlled from a switch in the headlamp nacelle with a parking light controlled by the ignition switch. Dip and main beam are easily operated with the right-hand handlebar switch after first being turned on at the headlamp.
