Of course the spokes are too long, the spoke holes sit much higher than the standard rim ones do, as soon as I saw those pics I wondered if they used shorter spokes, the outside can’t change size because you need to fit a standard size tyre on it so with the spoke holes sitting much higher in, due to that deep dish effect the rim has, it has to use it’s own type of spoke. Could mean you’ve got the right rims but the wrong spokes.
Oddjob:
I didn't realise you'd had them professionally polished Roo until I re-read your post on them. It's possible that they polished off the markings showing what the rim size was, especially if it was just lightly stamped or even printed on the rim.
If you still have the old steel rims you could try this. Place upright on a flat surface, get a small spirit level and place it on the highest point of the spoke hole, across the wheel, level the bubble and measure what the distance is from the lower edge to the flat surface. Do the same with the new alloy rims, the difference is how much shorter the new spokes should be.
You could also try lacing the front wheel with the rear wheel spokes, as they are 1" shorter they may fit. If they do at least you only need to buy or alter one set of spokes, depends on how much shorter they have to be.
You could also re-thread the spokes yourself, find out the size and pitch and just run the thread down the spoke more, cut off any excess spoke after fitting and trueing etc.

These are the wheels that came on the bike and the only wheels I have Ken!
That’s the problem……..
I’ve not measured wheels of this dirt before and never had anything to do with spiked wheels before re-lacing the 400, they were standard though so it was an easy search, buy and re-lace.
Apart from that faint 40 which as you say is for the number of spokes…..there are NO MARKS ON THESE AT ALL!
Two more photos front first and then the rear. Basically they are not right so I’ll have to get some more I reckon, serves me right for not doing my homework.

There appears to be some occlusion in corrosion areas too. Worthwhile carefully inspecting after building for any disturbance around the spoke Wells to make sure non have been affected and will subsequently hold good tension.
Prime with etch, then something like gloss grey to give neutral finish.

I very much doubt they'll get used in all honesty as they're not right and looking back at the picture of the bike when I bought it I remember saying the wheels were odd and the bike sat funny, see for yourself. I think its gong to be a remortgage and a new set of rims tbh! A real shame as I really like these they look fantastic!
I wanted it rolling before crimbo so I could get the VFR on the ramp to get the back end swapped but it looks like another couple of evenings grovelling on the floor to do it as this isn't going to get done for ages now I think and without the rims I cant move it.
Least it gives me a bit of time to try and sort some replacements, and save up! :-[ :-\....
See what I mean?..............
