04 CR85 bogging

New to the site so try and take it easy on me. My sons CR85 cranks idles fine but bogs when i give it over a quarter throttle. I can get it to the power band and ride all gears with the front wheel up. Cleaned carb new reeds good compression. Purchased the bike second hand so not sure if it ever ran correctly. Assumed carb problems, put it in the shop and now they are asking me if i did anything to it. please let me know if anyone has any answers..
