Hey Big D,Ive heard the sleeve is no good for the K5,it will affect the performance far as the power and the temperature of the bike,my cylinder was worst than that. I took it off and my mechanic set it off to US Chrome (IT WAS STOCK BORE) it cost me $275, and they welded up the gouges ,REPLATED IT, and its STOCK BORE took about 3 weeks,top end was around $150and I went with the thicker head gasket to lower the compression will put mine together this weekend,I hope this helped you out ,keep me informed JohnJR. Later
