Lets build a SOHC for less than a grand

He bought the standard size bearings and then had a machine shop grind one of them to make a straight swap from factory fit to comprise the kit. So that fits in with your experience here Trig.
Must admit that I didn't pay much attention to exactly what he modded but fitted a fair few kits to friends bikes then. Always no adaption needed, and all installed as original kit. Seem to remember that the bearing id was missing from one of the faces, suggesting that they'd just been mounted of a mag base and skimmed with a linear surface grinder.
Probably a little market here for correct set nowadays, that would fit properly as most seam to come up with the problem you observe.
I've always felt as Erny does, they make a good mod for these bikes and are much move resilient than ball races.

There is something not right with this top bearing. Sat down and went through a ton of tapper bearing spec's and couldn't find one that would work. The only way to get the top bearing to sit lower is to mill the head stock so, the cup sits lower.
One to one and a quarter turns on the top nut is not ideal in engineering ;)
K2-K6:
Think it is as you find it, standard bearings will give the discrepancy observed and seen by others on here with kit parts.
What Degens did I'm not sure but they do fit. Vague memory is that the bearing numbers where missing from one of them, suggesting that both the cup and centre had been ground to reduce overall installed height and bring assembly within range of Honda fit.
The rollers stay clear of the narrowest taper point as far as most of them are arranged, giving scope to grind that face and move the outer track down into the frame without dropping the rollers through the track at their narrowest point. That along with a grind of the top most bore track maybe would get it there.
Friend has an old K6 with one of those sets installed, but don't think he'd want it dismantled to just have a look. :)

Going through some old boxes and came across an old Cibie headlight. I know that oldjob has said about these before but, I have never really had a good look at one. They have a reflector in front of the bulb and a clear bit of lens on the right side only.
Found some old clock, which I think are 550K1 or K2.

Cibies were always the Mutts, expensive, nutts only bettered by C E V Marchall which had 2 seperate bulbs

Looks to be a UK spec Z180, which is the best one for bikes.
They have a very long reach left hand illumination that is kept away from oncoming driver's view on dip beam, so particularly effective for the rider even with vehicles coming the other way. Also helps to keep that range even when lent over.
Very fancy ;D a pukka vintage piece.
