So how can one get a bit more track speed on this sled? 2007 carbed 600 ho 144". Gears are 18/41 I believe. Slp pipe, can, intake. It just doesn't like to spin the track very fast on the deeper days. Anything aside from boost or big bore? Running 10k ft. plus usually. I know it's a 600, But it seems like it should have a bit more. Is the gear ratio right? Seams wierd to me.I was thinking a 19/42 would be better.
