well the new battery died because I over charged it, its supposed not to discharge but it went down to 8 volts and as a battery, 8v is not enough.
So I went back to the alarm battery system and the bike starts a treat. For £7 I'm not fussing if it goes again I'll just buy a new one :)
updated the airfilter inlets as the old air filter tubes went hard and I couldn't get them on the carbs.
I am running a crank breather tube into an old deodorant bottle as a catch bottle.
