Bike doesnt rev or dies when pulling off on an incline. decline and flat road is fine and if i just ride up the incline without stopping its perfect. no flat spots in rev or anything. only the revs either die or dont raise when pulling off on an incline. and the bike has a full tank?
The float level in your carb probably needs to be adjusted. If the gasoline level in your float bowl is borderline low, your bike may run fine when level. But on the incline, the gas level at the jet may be too low causing your engine to be starving for gas. The solution is to remove the bowl and bend the tab on the float that pushes the valve up so that the gas won't shut off until the level is higher. If you are a good mechanic, you may try this yourself. If not, take it to someone who can do this for you.

replace the fuel pump or adjust the TPS. It doesnt do it in nuetral its because it is not under a load. Put in dealer mode to check the TPS. It should read -COO... If the - is not in the middle (if its up top or on bottom) it needs to be adjusted.
First impression was why would anyone rev their motorcycle to 9 grand in neutral? I could see if you were in gear clutch pulled and ready for a "drag" or Race Start but in neutral?
Anyway I can't hear it so if the sound is like it hits 9k and starts popping then two things either an over rev limiter which I doubtr because the engine red lines at 13,500 OR you have a set of spark plugs breaking down under load
run a can of Seaforam in the tank..purchase from Autozone put in 1/3 to two gallons gas drive it around for at least 10 miles to insure it cleans out the whole carb system.if that doesnt work, check all carb hose fittings when bike is at idle spray some Chemtool B-12 ( also at Autozone) around the carb hoses and manifolds..if idle increses thats your problem. Caution: chemtool is very toxic wear gloves and a mask.
This is an interesting problem, firstly did it start doing it after fill-up? if so you could have got a dose of bad fuel, simple drain and refill should have it going OK, don't forget to drain the whole fuel system. Secondly check to see if any vacuum lines have come off, if this is the case listen for any light hissing noises and chase it out. Thirdly Check you spark plugs for fouling and any cracks in the insulators, it could also be a coil breaking down.
Have you checked out the fuel pump? Check the fuel pump because Ford did put out bad pumps. My 99 did a similar problem of stalling and or shutting off when on inclines or declines. Turned out that 3 out of the 4 welds broke on the fuel pump in the tank and caused the rubber line to pinch and starve the motor of gas.
