the reeds deal more with bottom end "responce" not exactly mid range... when was the last time your powervalve was cleaned? i have a suspition that your powervalve is sticking... it's common on bikes now-a-days... i doubt it would be the carb since it runs fine on the bottom end... just pull the powervalve cover off and turn it by hand... see if it turns/ moves freely... then worry about the carb.. |
