Does anyone know what i should be getting for MAX Rpm's at full throttle? I have a 2004 F6 EFI...

7800ish is the sweet spot. A F7 7700-7800 is the sweet spot as well.

Thanks tons acemaster101 ---- I just got the sled fixed 2 days ago... Fired it up last night... Have it up on the rear stand track off the ground and i can only get 7000 rpm's out of it... Is this power valves sticking? Clutch sticking? or should I not worry about it since its off the ground.....

No their is a problem for sure. Actually when theirs no weight like that, it should be ovvver revving like 8100 or soo. For sure start out with cleaning the power Valves. Adjusting them. Make sure your plugs arent fouled. See what happens... If it still runs like "Sh*t" Make sure your compression is up to snuff. And if it is 125-140psi. Then you should look into rebuilding your clutch's. YOu may need new bushings and a good old fashion cleaning.
