Trade AC 900 ported cylinders for 900 stock cylinders

[lightcat900]

I have a set on very nicely ported ac 900 twin cylinders and cpi twin pipes that go very well with each other. I would like to trade this for stock 900 cylinders and a single pipe plus... Make me an offer. Reason I am doing this is because I want to go with a turbo.

Who ported them? I have a stock set I need to port, depending on what was done to yours could possibly do a trade.
Pm me with info.
