I recently acquired a 2000 ZRT 600 with D&D Drag pipes and powerbreather & Delta 3 V-Force reeds. I went through and cleaned the carbs, painted the pipes, and adjusted C-C and Parralellism to ensure proper running this season. The sled is a dog untill 30mph, seems like it is ALWAYS loaded... I even try keeping rpms up to 4500 to let it breathe but it still is slow out of the whole, anyone have any idea for carb adjustments? I am running at about 20 farenheit in Northern Michigan. Please help I know this sled is capable of more than it is putting out.
