    Yamaha uses the first 3 characters as an ID. So, if it is 1JY, closest I've found is a 4JY, a YZ 125F from the '90s. There is a 1JK from an SRX 600, 1J7 from a XS 750D. I also found a valve stem seal: 1JY-12119-00 YAMAHA VSYA-1JY .252x.410x.355.224.

    Give us a clue; what are you looking at?
