need power loss ideas to look for

I recently put my bike in the shop for spring maintenance.When I got it back I took it done the road and it stalled.I returned to the dealer he took a look everything seemed fine. I noticed that when I go up hills I have to wind out the engine to maintain speeds,this was not a problem prior to putting it in the shop They did the following work cleaned the carbs,changed the plugs,oil and replaced the boot from the carb to the manifold.I found the boot loose and leaking fuel so returned it to the shop.They fixed the boot checked compression (137 lb.s) fire on all cylinders and synch'd the carbs. Still no power if you want to go over 60 mph you have to down shift to 3rd and rev up. Also noticed the pick up is slower when coming out of a full stop but not real bad about 3/4's the power it used to have.Throw me a bone fellas.

Garage
Have them take off, and double check all the carb work that was done. Do not let them charge you a dime to do so.

Sounds like one carb is stopped up. Or it may be flooding.
