With not knowing if you bought them or built them makes this hard. Nice looking machines for sure! Compression will be the result of hard starts/no starts if you have spark. I go for the simple thing first for the 90, is the switch on the headlight bucket turned on? Disconnect the kill switches on both machines effectively bypassing them. Did you unscrew the spark plug boot and trim a 1/4" of wire off?
