I know that the Suzuki engines are what power the Arctic Cats. But i was reading a review in Jan. 2001 4-wheel ATV Action about the the Quad Runner and it got me thinking. The review said: "If you have spent time on other big bores, the QR's motor will not impress you with its strength. It does not have nearly the pull of other machines in its class, but it certainly has the torque to far exceed its towing and hauling ratings." The review also mentioned that it was the same engine as the AC. Yet the AC is always boasting such power and grunt all the time. And even in other shootouts with the AC they always seem to commend the AC on being so powerful. So i was wondering if Suzuki and AC tune the engines differently to produce different power bands or if the engines are the EXACT same and the Suzuki 500 and AC 500 are infact equal in their power capabilities? Or if different testers are having different opinions about the same engine?
Does anyone know anything about this?

They are not exactly the same. I know the AC has a higher compression ratio than the Suzuki. That's one difference that I know of, hope that helped.

 

The compression ratio is Higher on the cats, the carberator is different(since the 2000 auto and 2001 on the rest), the muffler is obviously different, and thats all I KNOW of for SURE. I'm gonna see if I can get my hands on a Suzuki 500 repair manual tho.
