I used to have serious charging problems on my cb550. I'm running a stock harness, but the best change I made to the harness was to add a ground wire connection to the frame of the bike. I soldered a pigtail to the green ground wire up near the coils and added a ring terminal. I scraped the...

I've got two of these beasts. Every time I've had a problem with the main fuse popping, it's been due to a buildup of tarnish on the brass connectors. At the very least, you should clean all the brass blades on the fuse block with a good metal polish. If you want to make sure you've solved the...

Great article. Thanks!

The frame of the k model is identical to that of the f model. The seats and tanks are interchangeable.

Looks like the valve adjustment cap on #3 exhaust has been leaking. I would start by replacing that o-ring because that's the easiest. If that's not the problem, then it has to be a leaky valve cover o-ring.

Re: 1977 CB550f Grade A- for sale! Dallas, TX Gorgeous bike! However, it's a CB550k, the base model, not a CB550f which was the super sport model.

That's the tube where the original brake lever assembly would rotate. No need for it if you're not putting the original brake setup back on.

I just bought a couple of things from them. They're fantastic. No hassles and the parts were delivered within a few days.

If it were me, I'd get a nut splitter on the nut. Some places call it a nut cracker or a nut breaker. Here's one from craftsman, but I'm sure Harbor Freight must have a cheap alternative. http://www.craftsman.com/craftsman-nut-cracker/p-00904772000P This is how they work...

It's not enough to loosen the jam nut on the cam chain tensioner. You have to turn the adjuster bolt counter clockwise as far as it will go and tighten the jam nut in that position to get the tensioner to back all the way off for maximum slack. If you just loosen them jam nut, the tensioner will...

You have to tap the sprocket sideways slightly away from the flange that the two bolts threaded into. Theres a shoulder that the sprocket fits snugly on and it may be stuck a bit. Tap it with a soft face mallet. Once it's free, there will be a large notch on one side of the Center hole in the...

It's a diode that works in conjunction with your starter switch, clutch switch and starter motor. It makes it so that if the engine is in gear, the starter motor won't work unless the clutch lever is pulled in.

As minicafe said, the neutral light ground wire must run to the neutral switch. To get the aftermarket speedo to work, you'll have to split the ground so that only the high beam and indicator lights are grounded to the bike and a separate ground goes from the neutral light to the neutral switch...

the wheel assembly parts that are not shared between the 550k and the 550f are the spacers on either side of the wheel. The sprocket side spacer is held to the wheel by the sprocket cover. Both spacers are longer on the 550f, so if your wheel assembly is from a 550k, the spacers will be too...

Looks a little like what they used to call a "king and queen" seat.

Parts fiche is the place to start. You can find all of the ones for your bike here: http://www.servicehondapsn.com/fiche_select2.asp?category=Motorcycles&make=Honda&year=1978&fveh=131104 The fiche has diagrams and a numbered list of the parts in the diagram. Every bolt in the diagram has its...

Axle length isn't the problem. The axle fits properly in the swing arm without the wheel installed. Something about the wheel stack is wrong but I'm stumped as to what. Sent from my iPad using Tapatalk

The spacer on the left is built into the sprocket cover. It goes on the hub before the sprocket cover gets bolted on and it's locked in there. It only fits one way, so if it was wrong, you'd never be able to put the sprocket cover back on. From the pictures you posted earlier, it's protruding...

I suspect there's something binding in the wheel hub that's not allowing the brake plate to slide all the way into it. But pictures of the mounted wheel might shed more light on the subject. Sent from my iPad using Tapatalk

Yep, that sounds right because the tabs on your swing arm are thicker so the spacer should be shorter. Well, we've eliminated almost every variable! Mount the wheel the best you can and take pictures of it from the same angles as before, also where the brake panel meets the hub. I gotta go out...
