The starter clutch assembly itself costs about $250 (last time I had one quoted). The starter should be around $30 delivered if you get a used SM-14 from a parted CBR on eBay (we have many threads about that). There is a gear in between the starter and the clutch, I don't know the price but it should be around $75. Battery: $75 for a Yuasa, half for a non-Yuasa. You'll still need the starter motor bracket (around $50 if I remember correctly), the battery box (don't know the price), solenoid (so many available), and wiring (it should be pre-wired).
