sleeper06 Posted January 16, 2010 Report Share Posted January 16, 2010 You can do a quicky with a caliper ,digital is easier.If im not mistaken top of cylinder to bottom of exhaust is 54mm for standard stroke,4mil is 56 and so on.Piston will sometimes have sizes on them like 513(standard),795(stroker)followed by bore size like 64.50(.020 over).Thats the easiest way to tell unless you have some machinist tools Quote Link to comment Share on other sites More sharing options...
BLOODRAGE Posted December 25, 2011 Report Share Posted December 25, 2011 some good info here. was having a hard time figuring out this superior sleeve jug,look at the exaust flanges how they meet the motor mount.it was said it was set up for a stock stroke crank so i did the measurement as posted and it was 56mm with 77mm pistons Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted December 26, 2011 Report Share Posted December 26, 2011 I would like to clarify that having 513 series or 795 series pistons tells you nothing about the stroke, but rather the rod length. 513 series are for a std (short) 110mm rod and the 795's are for use with the 115mm (long) rods. People may even use blaster 573 series pistons with 66+mm bores and long rods. -Brandon Quote Link to comment Share on other sites More sharing options...
