thanks, that's the exact part # i need, but i'm hopeing to find a used one. give me a couple weeks to call, and surf the net to try and find one. if i can't, i will be in touch. thank youHey 88twrookie. I have a bran new OEM CDI I bought online. Long story short I thought the bike was a 1989 instead of a 1987 (oops). The part number is 2YG-85540-M0-00 and it fits years 1988-1996. Brand new it was about 300 to my door. How does 250 shipped sound?
