Thanks for posting this. I have a 1984 Polaris Aktiv Grizzly which has the Polaris/Fuji 440 twin engine in it. It does not have enough power for such a heavy machine and I am in the process of replacing the engine with a Rotax 503. I hope this will make it pull better. The little 440 probably has nearly as much HP as the 503, but it has very little torque. I assume your Grizzly has the Rotax 503?
