What petrol do you other Yamaha sr250, 82 model use? My other bikes are all leaded fuel vintage so I use 98 and add a little Valve saver (flashlube) each fill. What is best for an sr250? Would be interested to hear your opinions?
What ever runs best. Some bikes like 91, some 95 or 98. Try a tank full of each and see which runs better or goes further.
