All Complete Cylinder Works Big Bore kits- $400 Shipped in the 48 states- Available for the above models

so $400 shipped for a nickel cyclinder and a venom piston for a z400??

also what bore size?

pretty sure he means just the c/w kit with the wiseco piston is $400. and its 94mm

they are 94mm for the LTZ400

no, with the venom pistons it would be $200 for the cylinder, $49.95 for the gaskets and $245 for the venom piston


if you want the $400 deal, it would be the cylinder works kit which comes with a wiseco piston
