Have had the sled for 3 years and from new would pull 8200 rpm all day climbing and playing in the 6000 foot range. Last couple of trips the sled was only pulling 7800 rpm. Dropping down on clutch weights had no effect. Sled has 1600 miles on it. Checked exhaust valves and they were clean and springs were good. Any other ideas/suggestions on the possible loss of rpm?
Thanks

When you cleaned the valves did you clean out the small port in the cylinder?
