Correct, same stock length con rod. Usually the longer the rod, especialy when stroking, will give the best overall results. When packaging becomes an issue, piston availability,cam chain length, engine "stack up" heights for oil lines, engine mounts etc. Then you would have to shorten the rod to maintain the stock envelope for installation.........

Who did your kit for you? Thanks.


I got mine from Eric Gorr www.ericgorr.com It was in the $400-$500 range... can't remember precisely.

The only bad thing is if you want to ride at an sanctioned track they might not let you race in the 250 classes but I beleave that you could race in the modified class.


If you don't tell them, how will they know?
