Interesting, I have the same mileage and pull the same rpm.If anything a good set of adjustable weights won’t hurt. I’m still waiting for DTR to publish a full dyno report on the 650 fully out of breakin. Mine is turning 8250 in soft conditions probably more on hard conditions with 1200+ hard miles on original belt. I’m waiting to see where the 650 makes power fully broken in Before I spend any money, I believe the vast majority of owners are happy with the 650‘s performance I know I am.
Spot on! At 260lbs without gear, I've always had to take some weight out of the primary to get to peak rpms in other sleds...200 rpms as simple minus a gram per weight. The adjustable weights are great for this.You guys might want to report in on your driver and sled weight before worrying about a couple hundred rpms.Driver weight and storage bags or saddlebags full of gear will change the sleds performance 200 rpms easily.Thats the basic reason clutch kits dont work without adjustable weights to get it dialed in for every rider.Dont forget track and studding differences will also have an effect as well as your track adjustment itself.
