what are the cheaps modds for motor i have air box done to it jetted carb bore .8 over what the next step
sounds like you have the basics covered man, the only freebie i can see left is a timing mod after that stuff starts to cost money. but play it smart and be patient.. most are surprised to learn i have only about $22-2500 into mine total. BUT i have built it up over the course of 2yrs, just be patient and work hard.
