Thanks all for the latest replies, fresh petrol is the next thing on my list, I did reseal my rusty petrol tank, but at moment the bike is hooked up to one of those small portable plastic tanks suspended above the bike,being purpose made for the task the plastic should be good...maybe? The oil grade is interesting, i'm using a mono grade sae 30, wet sumping is always a problem, i fitted a drain bolt to the sump and usually drain it before kicking over. I'm investing in a compression tester as i think that needs looking at as i think I've tried most things!
You are right, of course, Ian. It was a long time ago and my memory is not always at its best when thinking of bikes I now no longer own. I had the B33's head off (for valves) and so I made the mistake of thinking there was a head gasket in the process.
No need to apologise...I frequently can't remember what I did yesterday, or what I have to do tomorrow....As for today, getting the day of the week right and remembering where I've put everything is the challenge...:laughing: ....Ian
