I find it very unlikely that you're slipping the clutch in lower gears but not higher gears. That never happens. Not saying it isn't slipping, mine was and I have less power. I went with a Barnett spring in this bike, last bike had the same internals and had an SE plate. Never slips now.
Unless you've been abusing it, I highly doubt the frictions need replaced. Mine were nearly new in dimension so I just inspected them thoroughly and reused them. I did find one aluminum chip (from machining) stuck in one of the frictions, probably been there since new.

. I have experience with clutches,on every thing from mini-bikes to 18 wheelers,and plenty of cars,trucks and motorcycles in between.And as caulk04 says,it just doesn't happen that way.

The bike in question dyno'd @ 101/112.......
I think I've abused the clutch by feathering it from the dig. Instead of just releasing it.
Can the diaphragm be changed out thru the inspection cover? If so, would the engine need to be rotated to access all the bolts?

Good numbers,but that's more proof that your clutch isn't slipping-believe us,if it's slipping,it's slipping in 5th and 6th. I don't know off hand about the diaphragm, take the derby cover off and look. You will have to turn the engine though, by pulling the spark plugs and turning the rear wheel.

This only occurs during a hard launch. And only at the top of first. If it happens, I shift into 2nd, 3rd and so on. No problems.
Don't even know what else to consider.......

I know what you're saying. It's like the bike goes into neutral. But if I back off the throttle and then easy back into it, it's fine. I think I noticed it for the first time with a passenger on board.

To your original question: if you haven't glazed the plates, an SE diaphragm will work. You will notice some increase in clutch lever effort, but very manageable. Primary fluid choice & fill level will also affect clutch performance. Syn3 is NOT a good choice for primary drive or transmission usage. I have used Formula + in my primaries like forever, with good results. H-D has now replaced it with a synthetic gear oil that has an additive package formulated for good clutch performance. I've read some good reviews & will probably begin using that product in the future.
