I have tried some myself for the first time.. I only did a mild port and cleanup port.. Its hard work but fun in the end.. Im not an expert.. but i know its important to know what you are doing! ... read read read.. and I would be happy to provide a lot of material i have gathered together about Blaster porting
 
there is a lot that goes into the port timing. with matching the pipe to blowdown timing and whatnot. i've played with it quite a bit. just start searching, sometimes the info is hard to come by, but just keep lookin lol. don't forget about the head. blasters stock heads suck. you need to change the squish band, both angle and clearance, and the shape of the combustion chamber. the top of the jug could also use milled, at TDC the piston is still .03 down in the cylinder.
