Anyone got a spare set for sale they will probably be getting bored too 1170 so bore don’t have to be mint but the fins and faces need to be in good condition

Im looking on ebay and found some barrels but they are not the same as mine
Mine doesn’t have a recess round the corner stud holes
What does that mean?

They tried different numbers of counter-bores; 4 and 2 and more and less and none. All leaked at some point. You can use any of the 1100 sets; z1100 shaft, Gpz1100 B and Unitrak and Z1100R1, ZN so long as you use an MLS gasket which i guarantee will not leak. Cometic one-piece and you'll have to take a chance.
If you have concernes beyond that you can swop the liners into your existing barrels relatively easily.

Looking at the parts catalogue it looks like the ones on ebay from Germany are A2 and have o’seals between barrel and head
