I setup a 2000 ZR 700 for a guy a few years back and he said that the sled rocked.
Drive Clutch = 55.5g cam arms (0746-559)
Red Sp. (0646-149)
Driven Cl. = Yellow Sp. (0148-227) 4th hole
57/50 heilex (0648-016)
Move the clip on the N/J to the forth groove as per Arctic Bulletin.
Exhaust "Y" pipe was smaller then the cyl exhaust port so ground them out to 1.700"
The engine was stock but had great compression.
