Primary Chain + F1 forks
Seabeowner:
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

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.
