Back with a 500 ....

I get that about the screws without a doubt. These look like a good alternative Nigel. I fitted Allen cap head screws on the 550 cases but thought they spoiled the look slightly. I will change them out yet but will probably replace or re plate old ones. Just my preference.

Seriously, try the new Honda bolts they are still using to this day, started around 1980 on bikes like the 250N etc.
They do the correct sizes, meaning if the specs say 32mm then that's what you can buy, not having to fit either a 30mm or a 35mm. Plus because the head is so small they can fit where a 6mm bolt with a 10mm head can't, like the ends of the camcover. The beauty of them is you can buy a job lot off Ebay, where a breakers has broke a late Honda and you get loads of them. Plus the part number system is very easy to understand, a standard 6 x 8mm headed bolt is 96000-0603200 for instance, that's a 6 x 32mm bolt, if you want a different size just substitute the 32 part with the required length, like 96000-0610000, which would be a 100mm bolt. You can search and check if they make a specific length very easily.
You can see them on this pic I took when restoring my L reg. Fitted on the rotor cover and the camcover.
Plus, just thought of this added bonus, any bolts that face upwards, like the camcover ones, don't get flooded with water etc when it rains, this then rusts the edges of the socket hole causing them to fail when you try to remove the bolt. They don't hold dirt the same way and are easier to clean as it's a solid surface with no cavities.

I've got these on my 500/750 - with a touch of coppersil I have never had any problems. Look original with no corrosion

That’s a nice looking restoration Ken. Very interesting regarding bolts and simple ordering number system.
Phil these screws look the part too. Thanks for link.

Picked up a spare swing arm and had it powder coated .... so today its raining and thought ... go for it !!
All went pretty smoothly - one surpeise was the swingarm that came off had the roller bearing bush setup - no idea if this is better or worse but I'll probably get it powder coated and keep as a spare.
The end result to me looks better as the original was badly scratched - but it is really hard to tell
