I picked up a 96, 98 and 04 blaster for less than 1000. I got 2 running by fixing wiring. 1 has piston damage. I plan on fixing up the 04 since it has hydro brakes. Should I just go to my local machine shop and find out what new piston I need or should I go another route? The jug is not scored and I'll never do anything other than tool around.
