My Project turned into a lost hope

There is 2 options here A) you miss understanding your machine shop B)You need a new machine shop cuz they suck. What size pistons did you get? stock is 86. If you got 86.5 then bore it to 86.5 if you got 87 then bore to 87. Also your machine shop needs the clearance specs of cylinder wall to skirt clearance, Then measure the piston and bore the walls to that including the clearance specs. The rings should have come with pistons. They need to be gaped just like spark plugs do, If the gap is too small, you need to use a ring grinder/filer and gap them to the right specs.
