My wife would have a fit if I spent so much on parts ;-)

Nice polishing, must have taken ages. Will you clear coat them?

One more person is talking about his wife (and again I am not sure that I understand you correctly).
I hope that everything is fine in your families Smiley
I don't want to make any influence on other's relationships )))

As for clear coat - I am not going to do anything more with those parts.
They are ready for installation.

sorry...but I must make this comment.
I'm sick to death when "guys" say "my wife would kill me if.....".
FAK! grow a set testicles guys....sheesh. I mean, I coordinate my purchases with our home finances but crap mates......don't get so hung up on your wives emotions about what you do or don't do with YOUR hobby.

I buy my $h!t for my CB1. I buy my $h!t for my 919...........PERIOD.
I dont' ASK for permission to buy stuff.....sheesh. Man I'm sick of reading those lines..."my wife would be pissed off if...."

Guys, the comment about my wife was intended as a joke and should have been taken as such. Maybe there are some cultural differences in our communications? I too will buy what I like for my bike. And VintageHunter my balls are quite big enough thank you ;-)

I asked about the clear coat because I was concerned that the polished parts would tarnish quickly. Here in the UK with our salty roads, especially at this time of year I would have thought that they would be in a poor state quickly. Or am I wrong?

Clear coat = varnish, right?

It's useless to use it with polished parts bacause it won't persist on a smooth part.

I made my first polishing in 2007. There is no any oxidation.
It can became a little dim over some time. But you can make it shine again with a felted circle and polish paste.

Thanks good to know because my cam cover is really tarnished. Did you polish by hand or do you have a polishing machine?

It is mostly manual work.
You will need sandpaper with different grit sizes, that can be attached to a drill or angular grinding machine. Also you will need felted circle and polishing paste (can't say which one is available in your country).
1) Get rid off factory paint. It's the most difficult step. Big areas can be machines with a drill/grinding machine. Little areas, corners and pits should be completed by hands. You can also use scotch-brite.
2) You should handle your detail with different grit sizes, starting with coarse and finishing with fine sizes.
3) make a final handling of your detail with felted circle and polishing paste.

Filter man: please accept my apologies. I momentarily snapped. There's no excuse for what I stated other than I was out of line.

Velos:
Hellava of hand polishing job there. Impressive to say the least.

Story continues...

Rear suspension - part 2
As people say: if you don't succeed, try again!
During performing shock spring swap from CB-1 to CBR893 (900) I encountered with a problem: stock CB-1's spring is longer than 893's. That meant a pre-load problem (left - stock CB-1 spring, right - 893):


 
Then I decided to keep 893 shock "as is" and integrate it with a stock NC29 progressive linkage (I wrote about it here).
I was naive and self-confident, because I was sure that I will be able to do it without knowing stock NC29 linkage position with full rebounded shock. As a result - I made this linkage wrong Smiley
In addition I made some consultations with racers and some measurements which brought me to a conclusion: 893's shock will not work properly on CB-1's weight.
The best option will be to use CBR600F4i shock with some valve tuning.
I bought 600F4i shock and made a visit to NC29 owner to measure his linkage position.
When I was "locked and loaded" with all necessary info, it was time for second attempt.


I got this F4i shock in terrible condition:




Shock was disassembled:




This shock is compatible with NC23 and NC29. To integrate it into CB-1 with NC29 swingarm it should be extended/elongated:



And it should be painted Smiley




Spring was sandblasted before painting:





Other shock parts was also painted:



During painting works racetech kit had arrived. It is calculated for bike and pilot weight.
It had arrived fast but one part was missing. I am still awaiting for it Sad



Second attempt of progressive linkage was successful:






Video Smiley

And some "bonus" photos from the polishing master. His job is awesome as always:
