hey guys i have a few questions on doing some cylinder work i have watched kens videos on here about porting a blaster cylinder and got the bug to try it myself i know you want the exhaust port to be shiny to keep the carbon from building up, i wanna take 1 mm off of the port too, also cleaning up the transfer ports aswell im also gonna bore and cross hatch the cylinder what all should i try to do with the other side i dont remember if ken gave any info on it that or i wasnt paying attention


thanks

he didnt for a reason... the intake is much harder to port it has to be much more precise... i think you can bring the port above the bridge down 1mm the bottom ports can go down know idea how far if you do anything the the bride it has to be straight and a whole bunch of other stipulations
