Looking good, well done on a lot of work.
I have been doing the 550F1 and thought it would all be finished by May, but it's missed the Summer and will wait until next year before getting it on the road.
Just starting on my 1978 K4 (didn't know there was a K4 until recently, but I think it is identical apart from seat). Hope my silencers are intact (they are Sankei,s, I presume not original, but aftermarket) as it's a shame to patch or put a 4/1 on it. But replacement is an expensive add on at the end.
What paint did you use on the crankcases and block?

Les, Difficult without a meter. But when the ignition is on and the kill switch is on you could check that you have +12V at the black/white bullet connector that feeds the coils by carefully connecting a small wattage 12V bulb between this and the bike earth.
Be careful not to short the black/white to earth otherwise you will blow the fuse or fry the wiring!
Also when the points are open you should also have 12V on them. That is all the moving part, spring and insulated terminal. A bulb connected between here and the bike earth should also light, but not so bright as the current is passing first through the ignition coil. (your 4.4 ohms)
Indeed the screws once chewed are a b****r. The original tool kit with the JIS driver with T bar would do them easy and such a simple tool.

Les, Just confirm that you have done hairygit's suggestion of running a + 12V direct to the coils. Or have checked that you are getting +12V (I assume you have a multimeter as you have measured the coils resistance) to the double bullet connector that supplies the coils. Should be the black/white wire on the CB500. The blue wire then goes from the coils to the CB pts for cyl 1-4 and the yellow for cyl 2-3.
You could even check the +12v with and without the coils connected. It should drop a little when the coils are connected as at least one set of points will be closed.

What I need is someone to make some 550F silencers. There seems to be a demand but I don't know anywhere that can supply. I have considered using an Motad silencer and chopping it and getting someone to fabricate a fitting to the collector.

Have both the F and K.
The inlet o/d on the Pd carb on the K is about 1mm smaller dia. (39mm on F and 38mm on K) (not great accuracy as measure using a £10 caliper from Lidl!)
On the K the rubbers to the inlet manifold are shorter and hence the rubbers from the carb to air box are longer.

Great individualistic features. Like the pipes, switches, headlamp mounts. The seat is almost invisible, how was it on your longest ride so far? Makes some of us look a bit samey trying to recreate 1974. But just shows we are all sorts, but love bikes.

Think that wiring may not pass building regs as I thought it must run run either vertical or horizontal from switches or junctions. Looks like the vertical wiring to the 13A sockets on the left is not in line with the sockets and the wiring to the hood is diagonal.

Saw the mention of the SS125 in the threads above and thought I would post a pic of my SS125. At the time I was only in love with it for 6 months and traded it for a Tiger 90. It's blue like the one in DS museum. Paid £189 (got £25 for my C110) for it when still 16 and rode it straight down to Dover as I remember. They say kid's grow up younger these days. I don't think so.
And I've never been to Suffolk, but feel a trip coming on.

Just a reminder of a topic that I,m sure has been covered a number of times.
As my 500 has become increasingly difficult to start over the last few months, I thought to get on with something useful yesterday I would investigate. It is fitted with Piranha ignition (remember them) that I originally bought for a Guzzi and then transferred to a Z650.
The spark looked OK, but when measuring the voltage at the coils it was nearly a volt down. A quick root around the shed revealed an old relay bought for some extra lights fitted to something years ago. Wiring this to switch power direct to the ignition system has made all the difference. Starts on the button.

Thanks for that.
And strangely both sets include the 8off 10x1.6mm O rings that go under the valve guides. I've never replaced them. Should I?

I have bought two different manufacturer top end gasket sets for my two 550s and both are missing the 6off "lozenge" rubber sealing washers that cover the access to the head nuts. Is this normal as they include the large wavy O ring for the cover itself? It is annoying as the they seem to be over £3 each, unless somebody knows otherwise.
Should they always be replaced?
I have some from a set from a 500 that I did a dozen years ago and I'm sure they were included. At least I'm OK for one bike.
Thanks

Thanks for posting this. Most of us with only one or two (or three) bikes only come to this problem rarely and can make mistakes at the first attempt. The pictures give me the confidence to get on with mine.

The downpipes on my F are pretty good and I had designs on getting the old silencer repaired or modifying another to suit.
DS ore OOS of the gasket (packing) that goes between the two. It is a simple tube, but does any body know what material it is or I should use.

This ones for Ash I think. Do you have a guide for fitting new HT leads to coils as my leads on the F are hard and cracking? The leads are formed to a tight bend at the exit of the coils and I am afraid to move them here. Joining pieces for HT leads seem pricey.
Plus, has anyone used Z650 coils or similar as they seem to have replaceable leads and will they fit if I make new mounting brackets? I still have points ignition.
Thanks
