I was riding my bike yesterday when the bike suddenly stopped with no warning. I took it apart that night and realized, the piston had some scrape marks and the rod had some up/down play (I heard it's not suppose to). I also found that on the right side of the rod there are some heat marks that indicate something got hot and maybe over heated cause the seizure. Either way, I am pricing out Crankshafts and for some reason Weisco and Hot Rods do not make an aftermarket crank for the 98 RM year.....? Is this true, do i have to have the crank rebuilt or buy an OEM one? Please let me know, thanks.
