it is a thumper racing kit you can buy. go to thumper racing. com and it is like $300.00. it comes with the slleve and everything, but u need to find someone to put the sleeve in or something along those lines....you'd have to bring it to a machine shop to have it pressed in.

Most shops can do a simple bore out,but if it takes a sleeve then you better find someone that really knows what there doing.
