Well hello there!

Hi and welcome from another brit what part you from? plenty of knowledge to be found on here
 
Welcome from another Brit,
Same question as Bigprop, which part of the UK are you at?

Great to hear that you have the old girl sorted, now you can focus on getting the grin back online.
 
Welcome to the jungle from the hills of Dartmoor ! Decel pop , caused either by an air leak somewhere in the soot pipe , or possibly a lean tune . What pipes are you running ?
Zard were on it when I got the bike never did it before all the valves and innards were replaced so I am assuming it's just the tune!
