That's really bizzare. They took a Nikasil plated barrel and put a steel liner in it. I've heard about them doing this to Aprilia's. Clever. Although the port angles are different on the 4FU. But very interesting.
Very interesting indeed, i'm sure you'll get some very nice power gains from that setup, with the o-ring athena head for better squish aswell as the aggressive ported barrel! Defo worth it if you got it at a fraction of the price.
I'm loving all the individual choices we're making on tuning, variety is the spice of life for sure :)
Will be sending my barrel off in the next few months to my tuner friend in Porto land :) well fooking excited.
