ive seen a few 530cc big bore kits online that just come with a new sleeve, piston and gaskets. now do these put out much more power while being reliable, and would i have to bore out my cylinder to fit the new sleeve? also are there any other good big bore kits for the zilla that wont break the bank

 

where did you find the 530 kit.I'd like to know about any big bore kits for the 500

 

theres a few places that have it. just go to google and search LT500 big bore
