So the bike is always ballistic fun but sometimes it seems to have more grunt than i expect from it. The engine seems to growl, burble and pop a little more. And maybe it'll pull a surprise wheelie. Maybe it's just me, but I swear it's the bike changing character. Any idea what could cause this. At first I assumed fuel, but the change doesn't coincide with refueling. I don't think its temperature. I'm thinking maybe the O2 sensor. The xsr700's ecu doesn't do anything adaptive, does it?
