Paint looks great, try a hair dryer to warm up those fork boots, that should soften them up enough so they will stretch over the lower fork leg.

Bomber, thanks for the tip.

Mark,
You need my bike to finish out your color palette.

Actually I'm thinking about that.  I moved the K0 blue/green to the later sandcast and I'm moving the red from the later sandcast to the early sancast so I'll have to do something with the K0 and gold just might be the answer. :D

It's a gorgeous color. The photos don't do it justice. I'm really pleased with the price and quality of the work.

Egar, would it be possible to post the color code for the paint that your painter used?  I'm about to be involved in a body work project involving the same color...love it.  I realize that it is a candy color and the code won't necessarily get me identical results, but any info would help.
If it works good, it looks good...

Zaipai,

Unfortunately, I don't see a paint code in what remains of the kit I bought from vintagehondapaint.com
I just ordered the kit that matched my year and color. It's killing me that the gold cb on the RV is just sitting there in the elements and has been for weeks.

Yea, that sucks. There should be a law that if a CB is being neglected you have the right to take ownership to give it a good home.  ;D

After using my new Honda bits and some stainless stuff from ACE, I managed to get the new headlight rim onto the bucket (hopefully, the wires are all connected correctly inside) and the blinkers are on. One is brand new, both stems are brand new. Starting to look like something now. Still going to have to rechrome fenders (I'd love to buy NOS on Ebay) and deal with the rotten pipes. Also need new tires. After that, I'm done on the big expensive stuff.

Just my own opinion, but we all know Honda chrome is not very good. I would forget the NOS front and back fender and instead have yours rechromed. I did that on mine for a cost of $125 front fender and $125 rear fender. Actually would be cheaper to rechrome rather than buy NOS. Again, just my opinion but even NOS has some flaws after all these years sitting on some shelf.

I probably will just get the fenders and taillight bracket rechromed. The plating shop in town quoted me roughly $350 for everything.

Johnie, yes it is Don the Dirtbiker's product. I had a friend shoot everything at his shop.

I have to say that with this build I find myself really shooting for detail compared to the last two 550s I fixed up. This is really more of a restoration. I'm just scared of the engine rebuild. I hope t runs OK. I've never heard it run....
When I look at old photos and compare them to more recents shots, I feel pretty good. For example:

Money is short right now, so I'm waiting to chrome the fenders and will use the existing rusty 300 pipes until I can replace them. Meanwhile, I am not getting the bike to fire up. I've never heard it run and it's just killin' me. The starter isn't working, so I tried the kickstarter. Turning over OK, so I feel good about the rebuild, but I put gas in the tank and hit the carbs with starter fluid. No go. Guess I'll have to see what's wrong with the starter. Maybe the whole problem is as simple as a bad kill switch. Keep pluggin' away...

looks awsome.  Now you gotta get it running awsome.  Have you checked for spark yet?

Still not running. My rebuilt petcock is leaking like a seive (sp) between the tank and the petcock. I have a new rubber gasket in the top of the petcock where it meets the tank. I don't know if I can screw it any tighter. Those weird gaskets for the two screws go inside the petcock, not between the petcock and the tank, right?

I am using starter fluid to try and hear it run for a few seconds, but nothing. Also the starter isn't working. The solenoid clicks but when I removed the left side cover to look at the starter pin and hit the button, I could hear it spin. When I closed everything back up, I'm back to a clicking noise. So disheartening. I'm resting now after a million times kicking it over and I've stuck the charger on it in case the new battery is too worn down.....not sure where to begin to check for spark....I just want to hear it run for a few seconds at this point. It looks so purty.

Egar, something I've found about starter fluid...it can be real tricky getting it into the engine with the stock airbox.  You might try it without the air box or at least without the filter inside.  If your timing is off, any slight back fire could burn up your filter element.  Also to get the starter fluid into the engine, turn the choke wide open, spray, kick it once with the ignition off to suck charge into cylinder, close the choke, turn on ignition and kick.  If your sure the starter fluid made it into the cylinder and it doesn't at least fire, sputter, or pop...you got no spark.  It's a juggling act to do a proper spark check with no starter motor, by yourself.
    On the petcock thing, I have had the same problem with freshly rebuilt and installed ones.  Try redoing it and lube all o-rings and gaskets with wd40 or even a light grease.  I've found this can really help the o-rings seal up tight without galling or twisting.
If it works good, it looks good...
