i got some good and bad news!
my 200x should have the right jet setup cause the spark plug is brown.
for the bad it boggs really bad in higher rev and i think the valves could be set wrong.

do you think its the valves cause i need to know what it might be.
i want to ride my 200x soon.

it's a never ending cycle for me i fix one thing but another thing is off

Air filter? Plugged exhaust? Timing chain tight?
For the valves you take the two hex caps off the top of the motor, put the motor to TDC (top dead center) you line the mark on the fly wheel up with the arrow. You need to take the inspection cap off the stator side case and grab a flash light and turn the motor over while looking at the fly wheel to match the line up with the arrow. Then get a feeler gauge and check the valve lash the space between the valve and the little pin in the rocker are should be around 0.03 (0.02-0.05) if its less or more crack the nut on the little pine in the rocker are and adjust it. THEN TIGHTEN THE NUT back up. Kick it over a few times (don't start it) get the motor back to TDC and check it again. The intake and exhaust are the same 0.03 so just repeat on which ever side you have left.
Good luck
