If it uses the pink coloured anti-freeze (OAT formulation) or possibly a Honda coloured version of the same, then thats highly resistant to degradation in my experience. 

Worthwhile draining to see whats actually in there as it is now.

That type is usually bought pre mixed, and very effective if no leaks are present. It'll easily complete 15 yrs without much change measured.

Unsure of practicality of using central heating product, thought they were focused on iron/ferrous/copper based materials. Not sure aluminium based is in much use for domestic system. Could be wrong though.

Triumph Stag, one of the issues with that, and running without corrosion inhibitors that are part of anti freeze, was the "silt" building up in fine radiator cores to reduce heat handling capacity.  Using a system cleaner, of whatever type, in this whole system, may run risk of aggressive action on the aluminium base that could do the same.

Is the radiator aluminium based too ?

Lovely bike it is though, another one with fab sound to it.

K2-K6:
I've looked it up, no they don't use that type anti-freeze OAT mix.

But if its Honda spec in there, still a good chance it's OK, to empty and inspect the contents in assessment of what you've got would be first check.

If its not been diluted with water previously, it lasts fairly well generally.

What a find, it looks complete and original. I'm jealous! I've been collecting parts for my own (long term) NC30 project for a while.
I think you're right about the speedo being replaced. Looks like a Type 7 1992 Japanese model which would have had the KPH version. Model information here:

Personally I'd keep the original colour scheme but I can see why you're considering the RC30 type scheme, its the best looking in my opinion.

Following with interest.

I don't know if you intend riding at night, or with the lights on,

A fairly simple mod that allows the use of UK H4 bulbs of a much greater wattage, with out burning the switch gear out,

All that is needed is a relay,2 special bulb holders, and a bit of soldering

The location is Lh side

Thank you all for the wealth of information, these bikes obviously have a special place in the hearts and minds of  the sohc fraternity  :).

I'll go visit HGB tomorrow Nigel and check out the anti freeze and I'll also contact Pete Hamber. I think rhevrad is aluminium but I need to check.

Ted, I like the idea of waterless antifreeze as once in it is supposed to last a lifetime, again I'll check compatibility first (and the cost of it!).

Magpie, thank you for that link, I've just read it but will read it again (probably many times). Jury is still out about the paint scheme but originality is king etc but I do like the RC30 colours, a bit of a classic scheme and Tim wants me to paint it parakeet yellow, it's tempting......😁.

Nice tip about the headlight John, is that your bike👍. Are those fancy rad hoses or just direct replacements, I'll probably have to replace mine anyway.

The bike hasn't been run since 2008 so I'll be checking it over properly before hitting the button to see what I have. The PO did look after it though whilst she owned it and I know she bought the best one she could find when she did buy it. She also gave me a Haynes manual and the rear paddock stand. She wanted nothing for it but I couldn't do that and money did change hands but I still have a really nice bike to work on even though I've never heard it run I don't think I'll be disappointed 👍.

Thanks for all your help so far and I'll keep you all posted with progress.
Dave
