colour of yokes and headlight shell
« on: September 24, 2019, 01:52:33 PM »
Started to refurb some of my old parts off my 500, I did this last in the 80s and the paint on them is now flaking like crazy.

Looking at the finishes on the yokes and the headlight shell I decided back them to do them in gloss black, thinking back though I'm not sure if that was correct. I suspect the shell may have been gloss but should the yokes have been satin black instead.

I'll be having the yokes powder coated but the shell will be sprayed with a rattle can, just need to make sure the finish is the correct one, although TBH I do change how things look if I decide it would look better or cooler in a different finish, I'll be doing the handlebar switches in satin black so maybe the yokes should match.

Honda  Paint code NH1 on the headlight bowl and satin black on the frame and all over metal parts. The gloss used by Honda in the 70's is now comparable to a satin.

If you have a frame done in modern gloss on a 70's bike it, looks too blingy and tacky  ;)

I had some stuff done for my 1300 last year, some were in gloss and some were satin, the gloss is very similar to the frame on my 500, the satin less so. I think the satin is far too dull for the frame finish.

See if you agree.

There are so many different levels of satin, yours looks very dull.

Personally I think that satin looks very similar to the satin that Honda did on the 750F2 engine.

If you look at Paul Gledhill thread on his K1. I matched the original 1971 Honda paint to do his frame, which was listed as a satin in modern day paint. Honda changed the black on the frame in 1976.

Yeah just trawled through all 18 pages of it  :o

I'd have said that was a gloss finish, it's far too shiny to be called satin. Satin was the colour of the 750F2 engine and stuff like the reversed comstars on the 900/750s DOHC bikes. Either way the gloss I've had done is not that far off that, possibly a little shinier but TBH I'd have polished the frame anyway so it would have ended up shiny either way.

Couple of things I noted on Pauls thread,

1. Did he ever tighten up the nut on the rectifier ? Things like that just bug the hell out of me.

2. The note from Hadleigh Custom says new big end shells fitted and yet further down it says exchange crank and rods fitted and "BIGENDS ONLY GROUND" If they'd ground the bigends it may be why the rod bolts are protruding past the nuts, makes me wonder why the felt the need to grind them in the first place, plus why are the big end shells listed under the replacement standard parts section, Honda AFAIK never did oversize shells just very slightly bigger shells, I'd say far too small a difference for Hadleigh to have ground down too. Did Paul use the 1000cc block? I gather not as he's using 0.50 oversize pistons so suspect he used a replacement block and bored them out OR rather you did on his behalf.

Nice to see there is a BZP plater closer to me than Allens, Sheffield isn't that close but it's closer than the Hull area. Need to get some stuff done for the 500, trouble is I only have some small brackets off the airbox right now that need doing and I'm not sure whether they accept me just posting them to them. May ring and see.

1. Yes the nut was tightend. The reason it isn't tightened in that picture is I was still trying to source a new/decent foam/rubber bit which goes around the edge
2. I doubt that grinding a couple of thou off the bearing journels would make any differance to the bolt length  :o
The crank and rods were uprated for the 900cc big bore kit, no I did not use the 900cc block or pistons as a new block was sourced and Trigger did a full top end refurb inc Re-bore.
The bottom end was also compleatly rebuilt. :D

Hadleigh may have replaced the rod bolts Paul with stronger ones to cope with the higher compression etc of the 1000cc kit. Certainly seems to have had a lot of work done on it.

You know what odd about that pic? It looks to be off a 500 as there doesn't seem to be the mount for the ignition switch in the middle, yet it's using the later 7mm bolts instead of the correct for the 500 8mm bolts.

Is that a 500K2?

Unsure of nos but it looks exactly like a k0 one I have here .

Either way I decided not to use it and recon the original.
Looks like part number ends in 305
Book says should end in 010 for my bike
