Power or lack there off

[Hook]

Hey GG fans, I have an 02 GG 200 EC and on my first ride of the year it worked great at first but after riding for a while it has no power under throttle. The bike just seems to keep bogging out. I've clean the carb, warmed the bike up and turned off the gas thinking it was the jet settings, put a new plug in, clean the LTR power value and nothing seems to work. Anybody out there ever experience this, would love to heat from you.

Sounds like the power valves aren't working.Take the right side valve cover & exhaust off,actuate the valves by hand & look into the exhaust port to see if they are moving.
