Pondrew said:There is one area of 'old' bikes which have to be right for me; the exhausts. Jap bikes, seemingly especially Kawasaki didn't make their exhausts very durable for the UK. So many old bikes have aftermarket exhausts, or dented and knackered originals. I have a real problem with four stroke bikes that came out of the factory with 4-2 or 4-4 exhausts that have 4-1 on them. Two strokes with Allspeeds or Microns also. All about the originality for me. Getting hold of OEM exhausts seems pretty much impossible or VERY expensive.
Allspeeds were one of the best mods my KH500 had.

Good luck finding a 70s Jap bike with an OE exhaust!
