carburator loading up

I recently acquired an 2001 C-10. I love the bike and it runs great once I get underway. At slow speeds the bike sounds like the carb is loading up. Sounds the same way at highway speeds when I back off the throtle. Any ideas.
 
Had the bike sat awhile before you bought it. It sounds to me like to me like you have some blockages in the low speed/idle circuits in the carbs. Most likely if you pull the carbs and give them a good going thru, you'll correct the problem. That would be my first thought, but maybe someone else has another idea for you before you to to the trouble of removing the carbs. Good Luck! Doug
 
It could be a conbination of what Doug wrote and a weak or restricted vaccum. Drain your carbs and check for sediment, then drain and clean the tank and check the petcock, if there is any trash when draining the carbs. Rust can cause problems with the petcock and eventually the carbs. I make that a service item every two years, at least.
 
ditto! and don't forget the pilot screws under those sealed caps. screw in until lightly seated and back out two turns is what i've read here. that's controlling your idle air/fuel mixture.
