93 polaris indy 500 EFI top end issues
This year I rebuilt my Polaris Indy 500 EFI with new crank bearings; head bored out 20 thou. over, new jugs. Since the rebuild I don't seem to have any top end. Machine has lots of snap off the line but bogs down @ higher rpm's. I'm not sure if it's mechanical, fuel or electrical problem.
