Fozzer has pointed out the paint code I used (Car plan), it was a good match for little effort from a local motor factor and even after using the bike offroad the paint was unaffected, it wont be a hard wearing as a pro paint job etc but it was ok for me and was able to keep the engine in situ.
Regarding your exhausts, see the thread below (or just look at the photos), I have pointed you to my heavily corroded original down pipes, it only took elbow grease, wire wool and autosol to clean them, far better than painting them and really easy to keep on top of as access is excellent.
