Building a K2 for a customer, tore the motor down and found it has a 900cc kit in. pistons are marked Hainst 900. measure 67mm. in good condition and within spec.
I know it has been asked before but I can't seem to find it with the search function. anybody know where I can get new ring sets? 1.5mm top and second, oil ring 2.8/2.9mm
Thanks Kevin
