well i got an 02 rappy with a moose pipe moose air filter and a 12 tooth front sprocket. i know the new z400 has close to 40 horsepower well so does a stock 660 rappy. so tell me how mine would do with my mods included against a stock z 400 in a drag race, on the track, and on top speed. thanks.

 

the stock 02 rappy doesnt have 40 niether does the stock z400, the rappy has around 33-35, and the z has around 25-27. but back to your question your stock rappy will win in a drag race, and on top speed. on the track though the z is about even because of the raptors poor handling.
