I suggest asking the shop which cables they are fitting - the difference between Yamaha genuine cables and after market cables really is night and day - only believed once experienced. Genuine is expensive however, so it's a fair bet that your mechanic has fitted after market and still has problems....
My bike had much the same symptoms as you describe (but not as bad), an after market cable improved things very slightly, a genuine cable fixed things to perfection and has required no adjustment or maintenance for 6000 miles use so far.
is it clean enough?
