How about spray on chrome? I can see the in the near future this might be the only option available as the chemicals used in chrome plating become banned.

Hmmm... Intersting suggestions. Thanks for these comments.
I will keep an eye out for TRW front guards and I will investigate chrome powder coating. Not come across that before - only zinc powder coating.

How about Chrome powder-coating? Not perfect but looks OK.

When restoring my 1968 B44, I looked for Triumph TR25W and BSA WD B40 mudguards as they are very similar due to frames being basically the same. So my front guard is from a TR25W from where I removed the paint before having it chromed. The rear guard was sold to me as being for a WD B40, again painted so I did same before chroming. HTH

I had to increase the hole size in my rocker feed bolt to 1.7mm , I also inserted a 1.25mm copper wire into the oil tank discharge return to slightly restrict and increase flow to rockers and valve . Cheers

I need some 1969 B25S mudguards. The old ones were chrome but were obviously rusted to some degree and they were painted (not by me). I could possibly clean and re chrome but that would be a lot of cleaning/blasting/sanding. Are there any recommendations of restoration or where to get some reasonable new mudguards. I have seen some on ebay but they would need drilling and are in India.

I think the originals were chrome. It might be possible to sand and repaint the ones I have but worth finding if I have any sensible options before going down the referb. route. .

Tried the screw extractor which didn't work.   I ended up getting the caps machined  out.   Totally epic battle.

Looks good, thanks.

Below from the BSA factory may assist.

Anyone know the overall length of the clutch pushrod, or where to find the info?
It's a five plate six spring clutch, so I'm assuming it's the same as the same year B33.
Thanks.
