S4R spins but won't fire (fixed)

Hi guys, here's a heads up about an issue with getting my S4R to start this year, it would turn over on the button but was very reluctant to start, this got progressively worse until it refused to fire at all, I spoke to Neil at Cornerspeed & he suggested the ignition relay might be faulty so I replaced it (£7 nice cheap fix) and bingo starts like a guddun now, when Neil saw the original relay (mounted on the side of the battery box) he said the early relays were notorious for failure due to not being sealed properly at the bottom.
