Starting to think about the next project and thinking of a K, but which one? I feel happier if I know that I am not throwing money away, I do like to be able to justify to myself that its worth spending the money

Its great to get nice shiny fixings when they come back from plating, but when you are doing a full restoration there is a alot to sort  I have found that the fruit boxes with trays are very handy and have also used the plastic trays used to hold cream cartons etc.  2014_0519eng0016 by nitram2010, on Flickr

I see some people have used the boiling water and Winter green oil, but I didnt fancy it.
Found a tip to use Xylene and concentrated Winter Green oil mix.
Winter green is the more expensive, but bought 500ml and 5ltr Xylene for about £30.
Not economic if you only have a a few rubbers to do, but as I have quite a few decided to give it a try.
You need to be quite careful in handling these chemicals and use recommended protective clothing, ventilation, gloves etc.
I mixed at ratio of about 5 parts Xylene to 1 part WG oil in a medium sized pickle jar with lid.
First tried on inlet rubbers.
The rubbers were rock hard, but swell up after soaking for a day or too, but dont leave too long.
It seems to work by the Xylene swelling rubber and WG oil then soaking into rubber to maintain flexibility.
Took a while for xylene to evaporate off after removed from mix and rubbers returned to normal size and now quite pliable.
Then tried with a small batch of rubbers including the unobtainable CB750F1 rear seat cowl rubber buffers.
With many of small mounting rubbers at £3 odd each and some rubbers unobtainable, may be of interest.
If the rubber has perished and cracked, this method will not restore.

Not sure if covered before, but I learnt the hard way that you need to drill out the staked points on retainer. Just use a 3mm drill to depth of about 4mm. Otherwise the threads get damaged and retainer difficult to remove.  2014_0507cb750B40023 by nitram2010, on Flickr  2014_0507cb750B40025 by nitram2010, on Flickr May need to gently warm outer hub with hot are gun so it expands to make easier. If threads do get damaged use a thread tap with same pitch as a scraper to clean up. I bought a new genuine retainer and it would not screw in. After cleaning threads with a tap it went in fine.

I quite like looking at before and after pics, so thought I would add some for my humble C90. It was everyday transport fot a neighbour of a friend, then sat outside for 25 years  2014_0129B4C900003 by nitram2010, on Flickr  2014_0129B4C900006 by nitram2010, on Flickr  2014_0129B4C900008 by nitram2010, on Flickr  2014_0203B4C900021 by nitram2010, on Flickr  2014_0203B4C900056 by nitram2010, on Flickr and after  2014_0430cb750B40001 by nitram2010, on Flickr  2014_0430cb750B40018 by nitram2010, on Flickr

Hi everyone Quick intro- I live near Guildford. Have been into bikes since a teenager, started fixing a seized Lambretta at age of 14 and now have a few completed bikes and a few projects. Most recent project was a UK reg CB750F1, bought from a friend, with a seperate removed seized engine. Have always enjoyed fixing bikes and bringing rusty heaps back to life  Look forward to learning a bit more and sharing some of my experiences. Regards Martin
