Partzilla.com is a wonderful database for finding out where a part number is used and they have databases for all 4 Japanese brands (Honda, Yamaha, Suzuki and Kawasaki) If you are headed off to a breaker for a specific part and you know what models used that part, it's easier to find what you need. You'll need a login ID for Partzilla and it doesn't cost anything. I highly reccommend it.
