Ok since I was last on here I now have one CB500 (and two engines) and two CB550s, so I hope you all don't get tired of too many questions.
Have been offered a new primary chain for a Kawasaki 1985 ZX750 and been told that it will fit Honda CB550 etc. Would be grateful if anyone has a spec of the Hy-Vo chain? 3/4" pitch i think.
Secondly, the three bikes I have all have different forks. Stanchions on my F1 are pretty much shot. Very deep pitting and more water than oil ran out of the fork leg! Anyone know how they differ from the later K3 and if you can mod between the two?
Thanks to one and all.
Hope you like the pic. It is my brand new CB500, Aug 74.

I know one of the Kawasaki's is the same but not sure which one, also 400 four. As to forks as long as you change either the complete legs as pairs or just the sliders as pairs you can mix and match

Honda 23131-426-003 is alternative to the ---323--part 50 link Hy-Vo chain (426 is a CB650 middle p/N)
The CB500 is definitely same primary chain as the CB400F chain. I am getting mine & the damper rubbers from Yamiya

This MAY be the equivalent Kawasaki part but please check first
92057-1075
Could also try;

63-139 may be the Tsubaki part number

Thanks for all this.
Now I am told the primary chain he has is also ok for a Kawasaki GPZ550
Some research on ebay showed item 251195052785 (copy and paste in ebay search) which is interesting. Forget the price , but is it true? He lists a whole lot of bikes for same chain.
The forks are a concern however as the F1 stanchions seem like rockin horse.. And according to cmsnl the damper parts are also different. Is there a supply of stanchions out there at reasonable cost. The pitting in the one leg must be a mm deep.

Interesting it doesn't list suitable for 400/4 as the part number is the same in both parts manuals. David Silvers is a bit cheaper than that eBay link anyway.

Thanks, will try Philpots later. But in 40 years I have never seen such a deep gouge out of a fork leg. 6 x 3 mm and at least 1mm deep.
Back on the subject of primary drive. I have ordered the dampers from cmsnl, about £3.70 each. Not sure how you judge if the old rubbers are knackerd, butt thought just their age would do it.
Primary chain: following up on the ebay advert I have come across this Kawasaki 92057 number at cmsnl. Fits the z400J (4 cylinder) that was sold in the UKin the early 80s, the Z550 Zephyr from much later and a few other kwackers. Marked as CHAIN,#63-139X50L
Obviously too much time on my hands, semi retired and B cold in the garage.

What do you think??
When do we get to 2016?

While the engine's in bits, have a look at those damper rubbers in the primary drive. Mine were rock hard and I replaced them.

Nothing of the sort !!!! ...just the type of skullduggery we need. Looks like the right chain ( same ref as in my previous post) Don't go entirely on my advice alone thought. Great price if it is but check who manufacturer is ..should strictly be Tsubaki .
Definitely change those rubbers , false economy not to. They get a hardened skin due to to oil immersion after all of those years. I had a 400/4 ones go rock hard on the outside after 9 years.
I bought my third Yellow F2 400/4 as a write off and the guy replaced it with a KZ400J . The Honda was written off because the tank had a scratch and the seat was ripped in the really minor 'accident' (Honda spare part prices eh) ! Someone told me the Japanese collect Z400J's ..dunno how true it is.
ITS TRUE:

I think Phillpots can do wonders even with really deep pits but you need to speak to them. Wouldn't consider anyone else and the forks will never rust again .. trust me I had a Kwak KZ650B1 with their forks hard chromed fork on it , left out in all weathers and never ever had a speck of rust or corrosion on them.

Thanks Oddjob. I have already made two wooden frames/stands to sit the engines upside down. Have stripped the old spare CB500 engine I have had lying around for years. Haven't attempted to removed the rotor yet though as was looking to find a way round the without the tool, Is it a 16mm x 1.5mm pitch? Can't find anything here.
The actual engine I am re-furbing is for the 550 F1. I think that they are supposed to be slightly less prone to gouging the cases, but even at 31k the chain is making its mark. I think rough running engines can cause this.

Lack of correct servicing and owner abuse causes most damage, remember use mineral oil changed at 500 miles then at 1500 and every 1500 (or every year) after, Honda say a filter every other time me say filter every time
-
Don't. think the wheel spindle works on a 500 but it shouldn't cost much for a dealer to do it if you take in just the crank. The Honda tool is about £35-40 as I remember so you need to have a few to work on to make it worthwhile
-
Is this any use?

Just my luck.
Lower rear engine mounting 12mm. Ideal for using as slide hammer to withdraw primary shaft.
Swinging arm is 14mm
Rear axle is 18mm
Nothing on bike 16mm that I can fid.
And to cap it all. Yes I was looking at the tool on ebay but thought the 4-way device would be a better investment. David Silver sell an aftermarket one for about £25. It has been OOS for a while and I got fed up with waiting and ordered a load of stuff from him on Monday and did not bother to put it on back order as I thought I could not wait. Stuff arrived Wednesday and yesterday they tell me the tool is back in stock and they charge £5.85+Vat for dely!!

You wana bring it to Gloucester i'll take it off for nowt!!
-
Thanks Bryan, but a little far. I'll get the DS tool. At least it will have a re-selling value.

Before you spend, a CB350/4 rear axle works as a puller for the CB500/4 Rotor. Use the wheel spacers as the slide hammer. The Puller for the 350/4 I used was an M18x1.5 bolt., or if you haven't got the CB350/4 Axle, an M16x1.5 bolt is cheaper than the Honda tool!
Regards,
Nigel.

Was looking at buying a bolt, but tool looks as if thread is turned off first couple of mm for location. Wheel bolt for Fiat Van is correct thread, amongst others I imagine. May try that.
