Got a 3i for the missus but im unsure as to which model it is. Its been played around with so im unsure if some of the tell tale give aways were there from factory or if some one has fitted them up ie air filter housing gone in place of induction kit, rear disc conversion and its had lockwood dials reading 150mph fitted (doesnt mean its not 130mph underneith i suppose). So how else can I check, throttle housing size etc??

Cheers,
Stu
