so its the 1st real run this year with my wifes 03 edge 800. it starts up and runs fine from cold but after it warms up it bogs out. i found if i work the throttle(feather it) its better but pin it or from a dead stop it bogs out. i had this before with a old 700 and it tuned out to be reeds. i pulled the one side out and they looked like new so then i started thinking exhaust vales? maybe?it ran fine last years same place temp all that, so not jetting. i rode about 10-15 miles fine then this bogg started. where should i look?
