Buying a vf1000f2

Looking at a vf1000f2 30k miles vgc looks a really nice bike, any tips on things to look for, i can see the collector box is looking a bit suspect what is it like to get hold of these and silencers.
Any help much appreciated

Good collector boxes are hard to find, but a member on here makes stainless steel replacements for them. See the thread section ‘In the Shed’.
