i have a 1997 ninja, how do i tell if it is a F2 or an F3, i know it makes me sound thick, but i could do with knowing 'cos i want to get a slightly louder end can for her.... and can anyone advise on a sweet sounding can for her????

cheers, ned. :999

I may be wrong but it should be printed on the log book (v5 document if in britain).

I don't think it matters as long as it's an F. All the changes were to the colour. I've just built an F1 in to an F2 frame and everything fits...
