13,8-- on the tach so i round it up. Not saying the tach is accurate, not say it's not either. Motor isn't stock. Pro lite piston with skirt trimmed about as much as possible, boost ported also. Motoplat Ignition system tha doesnt use a CDI box, just a coil, mini flywheel, and a timinig plate, BR7es plug. Like I said though, the tach may or may not be accurate i'm just stating what it read. No reason to lie about it. I couldn't care less what it said as long as it runs good.
