Thanks all. It turned out to be the rubber block hitting the rear frame bridge (the rear mudguard mounting point). I measured the new seat block against my genuine seat and it was 20mm thick, the genuine one is 7mm thick! I cut the appropiate amount off the new rubber block using a knife in-situ as I couldn't get the block off the seat, it would have destroyed the moulded bungs on the back of the rubber block where they push into the seat base. All now perfect . I have a buyer for the bike now, it will never be used as its going on display in his dining room! He's buying it as an investment as he doesn't even have a licence and has never ridden a bike before!
