[timmyboy]

Can anyone tell me what type of pistions these are and what they are for?the numbers on top are C00G4 and the numbers on the center of the top are 8963 and 70.45mm

if i am not wrong! those are the pistons that my big bore cylinders uses...

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.

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?

[gst_r]

yeah those are old school trinity racing pistons!

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...
