XCR 600's had "agressive" porting, 38mm carbs, different timming curves, and a slightly shorter pipe for higher rpm (8500 vs 8000). Total peak power was only 3 HP more (96 vs 93), but the midrange was vastly different on the XCR. Top speeds and acceleration were much faster with the "high port" xcr package. The xlt special was designed more for the trail with it's long cushy xtra 12 suspention, and smaller 34mm carbs for better fuel economy. Your sled by todays standards is still pretty fast when in tune and is a blast to ride when the trail is smooth and curvey. Hope you like it.
My uncle has a 1998 XLT limited and it's a 600. but doesn't have Fox shocks. it is a very fast sled. I ran it alot with a v max xt 600 and it was a fun race. they come alive with trip pipes. The earlier motors had oiling trouble also!
