XS650 Addict
Regardless of what srimer says, back in the day when Yamaha was racing these 650 with 750 kits. They welded the crank pins after truing the crank...They crack exactly where the welds are. I've magnafluxed several and always the same result I've done many cranks singles to fours and don't weld any of them anymore I haven't welded a crank in 15 years and its never been an issue but do as you will your just supporting your economy for doing it
