954 has no mid range power
Recent owner of a 954. Got an issue. I have had it Dyno tuned and went through the bike some. Previous owners removed the exhaust flap, removed the air box flapper and cables. No error light so not sure what he did to eliminate it yet. But even with a dyno, I have no power in the 6-7K range. It is incredibly strong up to 6K and if you stay on it (building speed) it will power on through with no difference. But if you are sitting in the 6-7K range and try to throttle in, you get nothing. Super weak. Almost as if you are over loading fuel or something. You can see a MAJOR dip in the Dyno runs at that range. It is consistent every singe run and every time I ride it. So its not something failing, its purposely doing it. I'm at a loss of what to even check since I don't know this bikes history. Its killing me riding as you will try to accelerate and the engine power just isn't there. Any advice or just a hint of what direction I should be looking in?
