    I like the idea. I did chrome on my fenders and tank because it was simpler, but I like the look of silver with the red frame, very limited CL77-ish (except I made my chain guard satin black and headlight mounts polished aluminum to break things up a bit). Do it!

    I like it, I'd put a small wing logo on the tank(less busy), and alloy or chrome rims(they make the tires stand out and good tires look good)

    Red is righteous! Rustolem Red is a close match for the Honda Racing Red. The black is a Duplicolor Black match color. This is a working man's 450. Some day I would like to get a good paint job, chrome and upholstery.

    How do your colours withstand the elements, scratches etc.? I know if I'm gonna do it on my own it certainly won't be perfect but I will at least use suitabe paint.

    Meanwhile I took some measurements in the cylinders. I knew I couldn't do a precision measurement because I was to parsimonious to get a micrometer or at least a real good caliper but the dial bore gauge gave me a good clue about the state of the cyclinders. Assuming but not certain that the old pistons were the original 70mm pistons (Yes, Honda is printet on the sides but I think I saw overbore pistons with the same print as well somewhere) I measured some impressive rust pits of up to 0,25mm deep all around the cylinder walls. No wonder considering the history of this bike. However, with a theoretical minimum bore of +0,5mm in any case I decided to order a nice pair of 71mm pistons on Ebay.

    They were send from Tokio to NY within 3 days but needed another 1 1/2 weeks from the NY to DC. Not that I'm in a hurry with my project but isn't it strange sometimes? Anyway, they arrived, I'm happy and so I'm planning to bring them to the shop tomorrow.

    I also found and bought a new cyclinder head on Ebay cause I thought that the two broken fins will be kind of annoying after all the effort. Two days later the seller cancelled the transaction cause he dropped the head at the post office and broke... guess what? Right, two fins... I was suspicious at first cause it was almost too cheap for the condition as shown in the pictures. I thoght the seller might have had second thoughts but we stayed in touch and he send me a picture. It shouldnt be this one.. too bad...

    I've got the cylinders back last week. The machinist said it was indeed a good idea to go for the 71mm pistons. That gave him enough space to eliminate all of the extensive rust pits. Unfortunately I will have to conserve the cylinders and put it securely in a box like all the other parts, because I will have to move abroad in a couple of weeks as I already mentioned earlier. My plan for now is to have most of the parts as machined, processed, primed and so on as possible before me and my family leave the country. The moving is quite an untertaking so there will be a delay of some months before life is established enough to reengage in this project. It's just realistic to think that the assembly won't take place before the summer of 2019....sigh...

    That's a shame... hate to see a situation where you're on the verge of it going back together and have to put everything on hold. Of course, if I'd known then what I know now (as in, hindsight is 20/15) I wouldn't have been so excited about a year ago myself, knowing it would come back apart only a couple months later and still be apart almost a year to the month it last ran. Good things come to those who wait, isn't that the old saying? still, not much consolation. Make sure the fresh bore is oiled up nicely so the freshly-cut steel won't rust

    Yes, indeed! It almost hurts.

    Send out the rockers to Delta Camshaft for resurfacing today. Don't know why I've waited so long...

    The colours have arrived so if I don't change my mind last minute it will be a silver/red CB77ish colour scheme.
