or is it just that it's 11 years old, and the seller was a lying toerag when he said it was well looked after?
I don't see why you need to describe the seller as a "lying toerag". You got the bike for £1700 and as far as the other posts you've made it does seem to have been relatively well maintained. Do you honestly expect to pay that little for a bike and not have to shell out a bit on getting it up to scratch? MotoBatt are flavour of the month BTW, just bought one and am happy with it so far.
Listen, mate, with the experiences I've had with biking and dealers/clubs/riders who've turned out to be total wasters in the last couple of years, I have very little patience with the bullshutters these days - and if he's says it's a well looked after bike and it's only cheap because he needs a quick sale, I don't expect to find I have to spend over a hundred quid on parts for it before I've had it a week, and in this particular case find rusted battery terminals connected to a loose battery.
I don't know what "well looked after" means to you, but to me it means it's been well looked after. Calling this geezer a 'toerag' was being polite. You think that just because I got it cheaper than many (but not all) of it's age, I should expect the seller to be full of crap in his description of it? Righto.
I know this is the age of mediocrity, where the minimum possible is considered acceptable, but I have standards which are second nature to me and, perhaps foolishly, I expect others to have them, too.
Anyway, I'll be getting a new battery, considering it's age I think it's probably not a bad thing to do in any case.
Thanks for the other replies, guys.
