what is it 20.6 hp at 12,000 rpm over 150 lbs.
versus 17hp at 8,000 rpm over 250 lbs.
stock for stock even with the blaster jetted and piped with a toomey which is aroud 21hp.
if the riders are equal then the cr80 or newer 85 is gonna spank the blaster.
But your not gonna get much over 25hp out of 82 or 84cc on pump gas, you can easily get 35 or more out of the blaster on the same fuel.
The cr comes in a much higher state of tune from the factory, but as the builders and racers say there is NO replacement for Displacement.
Just ask any of the titanium valved 4 stroke riders if they would have a chance cc for cc against the two strokes, they will stutter, whats gonna be funny is when the 2 strokes get full direct injection of oil and fuel, there is a pretty good chance that even a 450 4 stroker, wont be able to run with a real 2stroke race bike.
