STAGE 1 CYLINDER PORTING
PRICE IS PER CYLINDER. EXAMPLE: KAWASAKI JS750 WILL NEED QTY OF 2.
Stage 1: We describe this stage as blueprint porting. Removing all casting flaws, evening out the height and width of all transfer and boost ports according to desired use, adjusting roof angles based upon desired use, conservative exhaust port modification. This is our most common stage that we do here. It will offer the best bang for the buck and keep reliability as close to stock as possible. $200 per cylinder.
Stage: 2: All of Stage 1 plus a more aggressive exhaust port, mild modification to the sleeve skirt. $250 per cylinder.
Stage 3: All of Stage 1 and 2 plus heavy sleeve skirt modification, heavy boost port modification, and piston boost porting/ modification. $300 per cylinder.
