If it makes decent enough compression, probably. Might throw the piston off though, could get some skirt slap without the second ring. Just my two cents

yes, was popular back in day to increase hi rpm pwr at the expense of low and mid pwr. Sinlge ring wears faster. Besure jetting is not overly lean, as one ring will conduct less heat from piston to cylinder ..... alex
