My pride and joy. A 2009 600 snowcross sled. I swapped an xc gas tank on, set up the suspension for xc racing and put the factory engine under my work bench.
If you look at the picture you can see my gas gauge, put a mark on the clear tank for every gallon, made it easy to mix oil and gas, 3 oz oil per line. Had a 2 qt oil caddy on the tunnel that held a belt and tools
Replaced it with an F7 bottom end (true and welded) F9SS top end, custom pipe, cut the flywheel for 8 degrees extra advance, tuned for 180 hp at dtr, on pump 91, with consertive jetting and timing. Trail rode it for years. Was the most fun and best handling sled I've ever been on.
Clutch engagement was 6,000 wot rpm was 9000. Sounded amazing
