Clutch slipping after 7k RPM in every gear.

Clutch slipping after 7k RPM in every gear.
Bike in question is a 1990. I'm having a slight issue that's actually quite perplexing. Just as the title says, my clutch slips in every gear, but only right around 7k rpm. From idle to 7k, it pulls like a freight train- in 1st through 6th gear. I'm new to hydraulic clutches, but does this sound like an adjustment issue? Is there even an adjustment? To rule a few things out, it has proper motorcycle oil in it, and no matter if I'm going uphill or down, it slips at 7k. EVERY. TIME. I've been spending the majority of my last few weekends fixing everything else from the previous owner, but this one has my mind boggled.
Thanks in advance for your help.

I agree with Teeks
Mine does it at almost the same revs, especially when cold, especially in the 4 5 and 6 gears
It does improve when the oil gets to operating temperature, but I'd say you need at least new friction plates in your clutch. I know I do
Takes about 2 hours to replace them and not expensive.

if its not the clutch, check this, my 99 f4 did the same exact thing and it was a clogged fuel filter. i checked by temporarily running with out a fuel filter for a mile or so just to test until i put a new filter on it. if thats the case with yours you might want to get an aftermarket 40 micron clear fuel filter for carbs at any auto parts store, its a clear tube about a couple inches long, has a white plastic looking replaceable screen in it. its about 9 dollars. i did that because the small amount of rust and trash in my tank was clogging up the 30 micron oem filters every oil change. i tried the cheap three dollar fuel clear filters and found that they dont work good at all, they are too restrictive and dont allow the correct fuel flow.

It all adds together to find the weakest link, perhaps worn friction plates, or maybe a dodgy fuel filter?

You sounded like you were accusing me of putting BS on here. I'm not a bull**** shooter. The fuel filter was clogged and staved my carbs of fuel at higher rpms and the engine was hesitant after 7k-9k rpm, which I thought was a slipping clutch at first. BTW I've been working on these bike for 23 years now. I don't put anything online unless its my actual experiance. Lol, Geez..there will always be someone who loves to question and start a debate with all kinds of tech and theory crap in the middle of a topic. I'm sick of reading topics trying to find help and seeing where people start arguing and debating on here is all. Hope you get it fixed buddy.
