i was curious of the same thing about this motor and the seld
heres what FASTCAT told me
"the 1977 srx was built for oval racing. there was an optinal gyt kit for them that included circle m fuel injectors. hp was in the 98-100 hp range at 9800 rpm. It had a 2 gallon gas tank and weighed 338 lbs.It was and as far as i know still is banned from racing in isr sanctioned events. it was a political thing. no other sled could beat it when properly tuned and with a good driver on it. Truely one of the fastest production sleds of its time. still deadly as a drag sled. if they allow you to race it! here is a pic of one

AS a sidenote in 1978 yamaha built the SSR. Production numbered around 100 of these rare sleds. It had the same engine as the 77 srx but had independent front suspension,of a style that was not re- introduced until the late 90s
