A quick update.  The bike is now fully stripped down ready for a few bits to be cut off.  I found that new brake shoes and steering bearings had been fitted recently.  Had a nightmare getting the 32 year old swing arm bolt out - much wailing and gnashing of teeth.  Same goes for the center stand pin - had to grind the bugger off in the end - who needs a center stand anyway ???  Still can't decide whether to get the rims powder coated black, or re-chromed.  Either way the spokes are going to be zinc coated and the hubs polished - should the hubs be clear coated after polishing? Same question about the forks.

If you are looking for a new socket set (in the UK), I bought this one from Halfords last week, it is their 150 piece professional  set with 1/4, 3/8 and 1/2" drives, it has metric and imperial sockets and ratchet spanners.  The good news is that it on sale at half price  (99).  It also comes with a lifetime guarantee.

Also, I'll be stripping down the wheels tomorrow, don't know whether to polish the nipples, buy new ones or get them re-chromed - any suggestions?

Cool project you've got going on there.  I'm starting to really like these non-CB builds just because they are a little different.  In regards to the wheels, I love chrome or polished stainless spokies.  If you go with chrome it will require a bit more maintenance than powder coating. 
Most motorcycle problems are caused by the nut that connects the handlebars to the seat.

Cheers tsbigdog,

The bike was a mess when I got it and I'll be changing most parts. The good news is that it was mechanically sound and ran well.  A bit of grinding and wheel dismantling tomorrow, then it's polishing time.

Had a slow day.  I thought I would quickly strip down my wheels - wrong.  The spokes must be originals and at some point the nipples have got very rusty inside the rims.  I had to strip the front wheel down with an impact screwdriver and ended up grinding 13 of them off - bugger.  I was hoping to get the old spokes and nipples zinc coated, but now I need two all new sets.  I phoned around and got 3 quotes of around 220 ($340) to rebuild both rims with stainless spokes. - not happy.  However I have found a company that can supply the spokes for 110 (delivered) so I'm going to have a go at lacing them myself (just ordered a spoke wrench off ebay).  Has anyone used a swing arm as a stand to true their wheels? 

Also I had a bit of a time getting the front tyre off - the back is a no-no with the puny wrenches I have, but the local bike shop said he will take it off for 10 - not bad, but you'd think he'd do it for free to build up a customer relationship.

I managed to get the frame and swing arm cleaned and degreased ready for powder coating.  As I said before, the frame and swing arm will be red, but I'm not sure whether to have the triple trees red or black.  Will red trees be too much? I'm doing the bike red, white and blue, but I'm trying to be subtle about it - I don't want to look like a fat Evil Kenevil - so I've decided the rims and hubs are going to be powder coated black, which should be cool with the stainless spokes.

See ya.

Cheers TB_J,

Not much done today.  Had my first attempt at polishing, it's not bad, but I may go over it again:

A few bits done today.  One of them was the petrol cap, it's a real mess, but I be buggered if I'm paying 60 for a new one.  So I've filed out as many pits as I can without going all the way through - it's very thin metal.  I then wet and dried it and finished it off with my polisher.  It's not great, but I think it will look good enough when it gets chromed:

Result!  I've just managed to order a Genuine NOS MAIN / CENTRE STAND for 30 delivered.  Now I just need to spend a few quid on a length of stainless bar, do a bit of drilling, add a couple of split pins and the bike will have a brand new center stand and rear brake pivot.
