The Polaris EFI is much more waterproof than carbs. Think about all the BS you have to go threw when you sink a carb atv, the Polaris EFI is just changing the oil. I have had my EFI up to the "twin logo" and it still runs like new. So these problems have no truth to them. BTW I have not seen but one post that was bad about the EFI. As for the grizz and SP's power, the SP has more HP. However the grizz has better take off. As for the outruns, thats true up to about 55, but that big old 700 has more topend. But its not smart to race big-bores. Out pulls...um no, I dont think I even need to get into that one, I think most of the people here are smarter than that. outmaneuvers? from what I have heard the grizz is one of the most "tippy" atvs out there. Anyway just standing up for my quad and making sure no one buys those BS statements.



I have no clue what Yamaha has in the works, but Yamaha and Polaris have great ATVs out now. I dont think you would go wrong with either one.

 

Since you are going to be buying in the fall, you'll have a chance to see the new Suzuki King Quad that's coming out this summer. It's going to be a 700cc single with EFI and IRS. It's styled like the Vinson as far as looks go.

Suzuki makes some nice engines so this machine should be very interesting when it hits the dealers this summer.
