... Not sure what sled to recommend. I'm all for fuel injected though, for the most part it's for emissions, but my 9 gets better mileage than my brother's 500 carburated 
Seems Polaris big hp engines are now on larger/longer sleds. So the fuel economy might not be where I'm used to it being anyway. So if you like being up front... perhaps you're not that concerned about fuel economy anyway. All I know is no carbs = less trouble. With this in mind, I'll be converting my '74 Ford with original 351CI engine to fuel injected down the road... be it an engine kit or an entirely new engine, I don't care.
Ya can't knock a Fuel Injected until you've at least tried one. The RR appears to have optional tach? Speedometer? It's simply a racer sled with no options on it, just made as light as possible (hence the smaller gas tank). I don't think you'd get far on it, but you'd be up front like you wanted.
