Reading about DFI 2 strokes has got me dreaming! Ski Doo has a 800cc motor putting out 160hp! So thats 80hp per 400cc! Now thats a snowmobile so thats at crank so in a motorcycle lets say 65rwhp now lets take it to the number we 2 stroke guys like 500cc and apply it motor I love CR500 Using DFI we should be able to have 75rwhp easy! Now take a Service Honda CR500AF 214lbs add 10lbs for goodys DFI adds 224lbs 75+wrhp!! That should send the 240lbs 55hp 450s home with tail between legs!
