hey guys just a little confused of which cylinder to get for my cheetah build, ive been looking at this kit on ebay: http://cgi.ebay.ca/Banshee-421cc-Cub-Wampus-Serval-Cheater-Top-End-115-Rod-/350433372409?pt=Motors_ATV_Parts_Accessories&hash=item519774e8f9 it says it comes with "ported & plated cylinders". does that mean nikasiled?? i would kind of like the option of boring them out if needed in the future, some input on borable sleeves vs nikasiled based on experience would be great. thanks!!
