well... if you go vitos 240, around 500 bucks plus shipping and stuff then your running, but you should get a pipe, like a dyno port high volume, then a 35mm keihin airstryker carb to get juice to the beast and for sure give her some more air with the airbox lid off, if it isnt already off. maybe toss some vforce 3 reeds in there, then your rippin.
A port job on the 240 jug for you would be hard, due to shipping, but maybe you could arrange something like buy it, and get it shipped stright to flowtek, then get him to port it and shipp it to you. everyone says he does good work, and the vitos 240 kit could use some good port work, but IS NOT nessasary.
