Just bought a 2004 T660 turbo. My first 4stroke sled, and my first turbo sled. The sled is in too notch shape, one older owner, and dealer services every season. The sled overall is mechanically real good. Still have not ridden it, as we have not much snow! I would like any info on them, and what kind of performance I should get out of it. I have been riding for 50 years, and now a senior, so not tearing up the trails like I did when I was younger!
