I'm selling these as my diecast will be a rider. It's a waste to put the sprocket on a bike that will be ridden hard. I'll probably regret it later,  but....   I can combine shipping. I don't gouge for shipping, the cost is pretty much an estimate and if it's any cheaper I'll refund the balance to your PayPal account.

Hello from New Zealand.

I know this thread goes back to 2010 but has there been any progress
with the powder-coating versus anodizing question? 

1.) That is, is there a solution to the pitting problem of the anodizing on old aluminium controls?

2.) Also, should the parts be gloss black or satin black?

I'm taking off my controls and brake master cylinder this week and would like to make some progress so any help would be appreciated.
Thanks, TC

Nice work, I'm getting a lot of pointers for my own diecast restoration. Coming soon.

I've been lurking around for a number of years so thought it was time I joined. I own a November 1969 diecast K0 with engine late 11,000's and frame early 12,000's. As these bikes are extremely rare in New Zealand I had to import one off eBay out of San Francisco. I use it on the odd track day and also regularly on a monthly basis. Also, the group of riders I'm with do an annual three day group tour which I go on. I damaged the bike on the last tour so I'm going to do a comprehensive cosmetic restoration using mostly Yamiya parts. I've started here:

I'll post up some pictures of the freshen-up as I go. It won't be totally correct and as stated there will be reproduction parts but I'm not making excuses, she's ridden often. To be honest I don't have the cash for a sandcast, or rather I would have, if my motoring interests weren't spread so thick. I have another bike (1973 Kawasaki Z1) and a 1971 Datsun 240Z sucking up cash.

I probably won't have a lot to add to the forum but I'm very grateful that there is such a wealth of knowledge here for me. I have spent and will spend lots more hours looking through the posts and website so that I can at least do the best I can for my old Honda.
