BANSHEE HP Posted December 16, 2010 Report Share Posted December 16, 2010 C00G4 is just a juilan date of prduction, 70.45 is a 70.50mm piston, the 8963 im not sure what series of piston that is. what kind of motor did they come out of? id run those numbers by t.d.r or trinity see if its one of their custom pistons.

Spidy Posted December 16, 2010 Report Share Posted December 16, 2010 I think gst_r is correct about it being a piston for a big bore. Is there anything printed or stamped on the inside of the skirt? Little circle with a letter inside? Quote Link to comment Share on other sites More sharing options...
gst_r Posted December 16, 2010 Report Share Posted December 16, 2010 yeah those are old school trinity racing pistons! Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 17, 2010 Report Share Posted December 17, 2010 Its an old trinity piston. I've seen them in some of the older cheetahs that look like that, and I think some of big bore kits you can buy out of the atv magazines use them...
