PLEASE change the oil BEFORE starting and put some oil down the bore, kick it over, with the spark plug out and then with a 50:1 two stroke oil mix in the tank, give it a try. I've seen good motors wrecked due to over enthusiastic "Must hear it run and revving, before any preparity work, or time to warm through!  :'( :'( :(

I too would give it a clean and leave well alone, once the wiring, tyres, tubes etc are sorted. As for tyres, I think compounds have come a long way since 1976, so it should stick to the road better than my experiences.

All the best with the wee beastie Martin and good health, Bill

Thanks for all interest / advice.

Ok Bill I'll do as you recommend. Gives me some more time to do hopefully easy jobs on this bike. I've got some 2T oil from one of my abandoned project s (HOnda H100) and the Suzuki GT185 I had a couple of years ago and the oil is not old.

I shall be giving it a very thorough clean and have replaced some of the rusty fixings with OE types as near as I can get for the time being.

I've also tentatively polished some of the chrome and alloy with Solvol.

There's loads of stuff on Ebay / the 'net and I found a UK parts supplier with very comprehensive spares stocks in Banbury which is not too far if I wanted to visit them for a trip out / shopping list. I know a lot of the spares will be after-market and some of dubious quality however. As is usually the case NOS parts are ridiculously expensive.

So at the moments it's : battery, tyres and tubes, maybe a headlamp rim, indicators and switchgear to accommodate them and an air filter element. I seem to recall these models have the centrifugal oil filter which needs a special tool IIRC?

I inherited a load of literature off the PO's wife and have ordered the small Honda models so called "bible" for my research s although it's early days - all's going well. I've also got cash in my pocket from the CGT535 sale should I need it but.......I will keep a restraining hand on how much I spend.

It would be interesting Michael to compare notes on how these old models compare with their more modern cousins.
