Hi Rob, yes have tried CMS/NL and they don't have any in stock nor have they ever had them in stock but they can source from Japan but will take about 4 weeks
Same with David Silver and Lings Honda, can order them but no current stock in this country
I'm quite keen (obviously) as my bike is in a few bits with someone at the moment and I'd rather they didn't have to wait 4 weeks for a gasket before they can put it back together and complete the service. I'll get one in the end from Japan but just wanted to try and speed things up by getting one from the UK but that's just me being impatient. Thanks for your response anyway.
