Clutch slipping & oil level on LF200?

[guttafixit]

Hello,
I took the bike for a ride 3 days ago. Went up a steep hill in 5th gear. I gave it more throttle and it gained speed. 45 mph at the bottom of the hill and I was going 50 at the top and I didn't have it full throttle. No slipping of the clutch at all.
I went today to get it inspected and I noticed it was slipping a little.
I changed the oil and went for a test ride after fixing the front brake and it was slipping really bad.
The oil looks full. This is oil level in the sight glass. But the level on the dip stick reads over full.
One owners manual I found read that my bike took 1.1 liters (1100 milliliters)
Another one I found read that it takes .9 liters (1000 milliliters) to fill it.
I put 1000 milliliters in it today and the dipstick reads over. I'm lost. lol
Do you think this could cause my clutch to slip being over filled or not enough?
Is my clutch gone and I have to buy a new one?
Bike has about 400 miles on it now.

Any help would be appreciated.
Thank you, Dan
