H859CP Speed Pro Hypereutechtic Coated Skirt Pistons .030" over (37 miles on them)
H859CP Speed Pro Hypereutechtic Coated Skirt Pistons 10.6:1 with 58 cc head. .030" over.
I missed one rod when i was torquing the rod bolts, caused one piston to break appart from the shock of the slack in the rod when it loosened. it scored the cylinder to the point that i need to bore the cylinder an aditional .010" and oversize a bit more.I put 37 miles on the motor before this happened.
before I looked close enuff at the cycliner I ordered one new piston and set of rings. so I have 7 used pistons with 37 miles on them, and one brand new. all of them have rings and are ready to install. if you want i can give you the rings gaps. and pics. Thanks
