    Any likes or dislikes about WSM Platinum Pistons and/or mail order Boring jobs?

    Have a 1998 1100 ZXI that fried a piston,one of the oil lines from the oil pump split out and came off.
    I found a place on ebay that will bore,and send me fitted pistons,rings,bearings,pins,clips and a gasket set for $450. The pistons they use are WSM brand. Anyone have any in-site into going this rout. Seems like a very good deal after checking some prices from parts stores.

    Just rebuilt an 1100 STX DI engine with WSM pistons. Cant tell you anything for sure yet other than it runs. Has maybe 5 minutes total run time on the hose and on trailer in lake. Couldnt take it off the trailer because the driveshaft hull fitting was leaking. It has 135-145 lbs of compression in all cylinders with just the brief amount of running and no real break in.
