My sled runs fine but when you go to can the throttle at mid range is bogs down, Any ideas??? I have changed spark plugs and gas.

Have you ever cleaned the power valves?

 

[psmith64]

No i haven't it has 2500 miles on it, took it out last night for a test, if you pin it is maxs out at 6700 rpm, if you go just under full throttle it runs fine got it up to 80mph again you just cant pin it. I havent looked but the power valve is on each cylinder head?

Yes each cylinder has it’s own power valve. I suggest looking on YouTube how to take them out and clean them. I have seen issues as your describing from gummed up power valves.
