Speed increase in gear shifts

Generally, in the 1st and 2nd gear shifts, I shift gears at 2,500 rpm, I pull the throttle and press the clutch at that time, the cycle hour goes from 2,500 to 3,000, although I do not press the gas, this could be related to the clutch amulet.

I had the same problem with my vehicle, today I changed the clutch switch and it was fixed.
