thanks dave,will have a look at that later,spent the afternoon giving the bike a good clean and light polish to exhaust,as it looked a bit dull
forgot to mention,used some cleaning strips i use for plumbing to clean the pipes,took about 15mins to go from brown to shiny,made by rothenberger,plumb shops and diy stores,very quick and smooth plus they wrap round pipe so you just push pull then you could metal polish to finish,will try to post a pic
