I have replaced by standard bulb idoit lights with some 12v LEDS in a plate bolted to where the handlebars used to work. I have a single LED for both indicators. This is working fine, but I get both indicators flashing at once. I have some diodes coming to sort that out. Head light main...

Hi All, I have recently changed out a trashed CB550F 77 UK harness for a much neater CB550K3 77 harness as part of a build. I have replaced the controls for a single modern control unit, the head up display with LEDs and a new push start button mounted away from the hand controls All was...

Rebuilding my Cb550F 77 and am at the stage of putting the jugs back on. They fitted down flush fine, but when I backed them off 20mm and installed the tensioner, they won't sit flush anymore. The tensioner seems to prevent the last 4mm of travel. Also, when it is down the tensioner doesn't...

Hi All, I have a 77 CB550F and the wiring harness is a mess, with so many dodgy connections and scotch blokes with new wire going nowhere. I was going to spent hours rationalising and cleaning, but have come across a wiring harness for a CB550K3. Looking through the manual and there are...

Taken the head off my CB550F. Around where the valves seat, the brass ring is heavily pitted on cylinder 3&4. Cylinders 1&2 don't show anywhere near the same amount of damage. It looks like there has been something metal banging around in there. The piston surface looks pretty clean, tiny...

Have been working through changing switch gears and starter buttons and trying to work out if the battery failing to charge properly is down to the silicon rectifier. A number of things have happened which I think might be causing me a problem: Shorted a make shift starter button against the...

I'm in a dilema. I was going for a type of traditional Cafe style seat, but could do with option of two up riding. The cafe style versions don't float my boat. I quite like the slim seat style on the wrenchmonkees type build, but you can't show a picture of that without a tonne of abuse about...

My brake lines are past it and with the clipons the length between the lever and the brake union, with the switch as part of that, now needs to be much shorter. Has anyone replaced this? Can you run straight from the lever to the caliper? If so, how do yhou replaced the brake switch so you...

I want to replace the 'idiot panel' that shows neutal, indicators, oil pressure etc. These are old style bulbs. I want to make an alu panel with LEDS replacing the bulbs. Can I just swap these out without worrying about voltage difference requirements?

So...... Managed to get the controls off the old handlebars and unthreaded the cables. Clipons now on and controls connected back up. The bike won't turn over now. I have done continuity checks from the controls themselves and all seems fine, but have had a strange result with the magnetic...

Hi All........... Newby to the fourm. Based in Nottingham, UK. Picked up a 1977 CB550F the other day. It was a bit tatty and left me stranded on the M1 and a £210 recovery fee. Not the best start. I have been taking time off from the wife and kids to work in the garage and have so far...

I am sure the original Cafe racer ethose was strip it down, make it quicker, ride it fast. How much do people now think of function over form? I was showing my brother my plans and for all the money spent 'under the hood' he felt it was irrelevent as long as it looked good. I know there is a...

I'm replacing the standard bars on my CB550 for clipons. I am reusing the current controls in the short term and the wires are bulky and thread through the bars. Job 1 is disconnecting them in a way that means I can unthread them and still allow me to get them back together and working. Job...
