I just bought a R80g/s and I hope this second venture in the BMW world will be better than last one (a 90/6 dressed as a /5). There is something I do not understand with Beemers: everyone seems to idol the stock (Bosh?) white pot metal spark plug caps... Are they not too old by now and need replacing?? Born and raised in Europe I saw these caps on everything from mopeds to big bikes (DOT regulations) and I think they are ugly even when new! So any reason(s) not to change them (apart of the "jt is stock" wanking!)? Thanks.
