Default nikisil bores
I currently own a 2000cc vtwin kawasaki vulcan with this application. This is very new to vtwins. Some owners are experiencing 30k or so before jugs are shot, can't even be recoated. Seems that the biggest problem for v configured motors with longer strokes is excessive side forces at bottom of bores due to rod angles that exist in v type motors. Inlines and boxers it is not as big a problem. Ford actually tried this afew years ago calling it spray bore technology in trying to make a 4.6 displace 5.0. (no room for sleeves they said)
