SO, heading in a different direction with my kat, going to offer up my 1370 kit.
The barrels have all their fins, and have been fitted with GSXr 1127 sleeves, bored to suit a set of 5,000km old 2nd gen Busa pistons.
All that needs to be done is deck the barrels to suit the reduced height of the pistons - from memory it needs 3.2mm skimmed off the barrels. Oh yeah, your cases will need to be opened up to accept the sleeves. I've also got a head and base gaskets to suit
Chasing $800 - which is about what the machining and gaskets cost me from memory...
I dunno how many guys here are still messing with old air cooled stuff, but thought I'd chuck it up anyway.
Pickup in Briz preferred, but can box it up and post.
