Boy it is that time of season! I got out the fiberoptic scope looked @ my pistons can see most of the #'s first 4 are 2386 then the carbon gets in the way but TDW is clear as a bell in the center are these OEM? 1997 Sx600 I just want to know if the guy before me did the top end or not! Thanks! Dan

My money says they are Wiseco pistons. Do not ever remember seeing that many numbers on a Yamaha piston.

There must be 15 #'s & then about 6 more where the fuel comes into the chamber! I figured the skunk was lying to me about "all stock"
