CB500/550 / Probable Carb issue!!
« on: November 16, 2017, 04:43:31 PM »
Having managed to rebuild and clean my PD46C’s on my 1978 USA bike, get some temporary pods fitted and wired up a new battery I was all ready to fire her up.  New oil etc and the engine turned over a few times without the power.  New fuel in the tank.  Choke on and pressed the starter.  It fired up almost immediately and revved high but wouldn’t idle.  Happy with that until I realized she was only firing on cylinders 3 & 4.  Checked for spark which was good.  Assume therefore there is a fuel flow problem with nos 1 & 2 carbs.  Any ideas as they were all cleaned at the same time??

CB500/550 / New CB550 1978 Project
« on: August 23, 2017, 10:32:10 AM »
Hi all.

I have been a member for a while, previously when I was doing a light restoration on a CB400/4 which went OK was fun to ride but then I sold it on as I wasn't making much use of it.  I also found full-time work got in the way of playing with toys.
After 42 and a bit years of work, I am now released from such drudgery and can start doing these other things to keep me out of the missus hair!
Having owned a 550 many years ago (early '80s) I thought I would try my hand at another light restoration initially so I have picked up a US import K4 1977 build, 1978 MY in Excel Black.  Cosmetically it is better than I thought it would be - but like all of these has its issues.
1.  Clutch sticking - takes quite a heavy hand to move the lever
2. Nothing from back of carbs under seat - ie empty space.  So I will need the air filter system and battery tray etc
3.  Seat will need recovering and hinge pins
4. Looks like an after-market cruise control added to the throttle grip
5. Throttle and choke cables disconnected.
6.  carbs stuck so will get those off and clean them up.  Until then can't try starting her up and listening to the engine.
7.  Brakes binding and front needs complete replacement.
Otherwise chrome is all good, paintwork decent, and engine clean and turns over and all gears select.  I wonder if US owner was looking at modifying to air filter pods??
Not afraid of the work, but would like some advice on where I can find the bits I need (including new throttle controls), so I can get on with it.
Originally I was looking at doing some form of conversion, but overall this bike is pretty decent I am thinking of getting it cleaned up and running and using for a while, and then a more serious 500/550 project later.
I have been riding since 1971 with various bikes maintained myself of all sorts from old British, Harleys, and currently a BMW R1200RS for serious touring.
Any help thoughts or advice welcome.  I have been reading the site regularly and have already got some useful tips and links so thanks for that.

Hi all.
Has anyone got a pair of grab handles for a 77 bike they want to sell on?

Hi all.  Just joined and wanted to say Hi!
I have looked at the the forum many times and must say it is very helpful.  I have owned a number of SOHC bikes in the past 41 years and having sold a good 77 750 F1 recently I have bought a 77 400/4 with only 20k on the clock and in need of some general TLC which will include new spokes and rims and other cleaning up. Engine sounds and runs fine with no smoke and no rattles.

Have owned an eclectic range of bikes over the years and currently also ride a 2000 Harley FXDL for cruising.  However the best ones have been the SOHC's which is why I have just got another one!

I expect I will be looking for advice and can also give some experiences as we go along. Would also be interested in local ride-outs if enough people around Reading interested in the better weather!

Happy New Year all
