[QUOTE="piggywig, post: 13121, member: 350"] [FONT=Arial][SIZE=2]In a recent posting Tom wrote of adding a breather to the front exhaust valve cap, while the series D had a breather fitted to the front inlet valve cap and a recent photo of a lightning I saw had the modified or additional breather fitted to the front inlet rocker cap.
