i have a used one here. the seller said that he'd always had a bloody misfire that wouldn't go so he scrapped the bike. this was 3 years ago and the bike was just 24 months old. how weird was that!
anyway, i took it. so it depends what part of it you want but i may be able to help and also whilst I expect the WIRING to be OK, it is the UNITS they connect to that could still cause trouble.
regards
Taffty
