Well My DF250rtc has a CG250 honda engine clone and well it's a 5 speed manual transmission and for some reason even running on 5th gear at full throttle max engine rev at 8500 and can't even reach 40 mph even cars running at streets for 35 mph pass me with ease also engine ask for an upshift to quickly it doesn't even give me room to gain speed from the gear I am on which is very confusing! Not even a second and i have to shift from 2nd to 3rd in less than a second even when having throttle opened slightly. Do I need to change my transmission gears or what can I do to fix this? I Always have to run on 5th gear and at max rpms which are 8500 just to stay at a speed near 35 mph which make me nervous that doing so will reduce my engine life.

Have you changed the oil, it has a wet clutch so it needs oil that is for a wet clutch system otherwise the clutch will slip and not grab . Maybe that is your whole problem , they are supposed to get up to 65+ mph at least 60mph with ease.

I'm using Mobil 1 10w-40 motorcycle Oil changed 1 month ago ago and new NGK spark plug and coil I also inspected clutch plates and I didn't see any way however the outside edges of the clucth plates are turning from yellow to brownish burned color. Does that color change indicate worn plates? But my original problem has been there ever since I bought it. I tried running on highway speeds once but I noticed i was giving to much strain to the engine because it barely head 160 miles and I think that is still break-in period for the engine so I immediately turned back

Motorcycle oils are required for "wet" clutches that are constantly immersed in motor oil. Car oils will cause immersed clutches to slip and fail. Get Mobil 1 Racing 4T 10W-40 not the regular oil for cars.
Hopefully changing the oil will restore the clutch if not they may be toast.
