Hi, Thanks for your reply, Its funny you should say about the bolts at the back of the tank, I ended up taking my tank to a restoration place in Southampton and my tank was starting to crack in that place, the guy said that those tanks were notorious for that, anyway the long and short of it is that he took my tank right back to metal, sorted out the weak sports and lined the tank with an epoxy liner, just need to get a respray now....... I am taking advantage of the bike in bits and taking advantage of the long winter nights with all sorts of other jobs.....Pic of tank attached.....Roll on next spring.... Got my Well A'rd a few weeks back, Cracking mag. THANKS
