I am not familar with blasters, but based on what you've given, I'd have to say that the 27.5 is too small. Have you adjusted your air screw to see how that affects the idle? I don't know where the air screw is located so I can't tell you which way to turn it to richen or lean the idle mix. How ever if you have to go to the extremes one way or the other to get the engine to run better that will tell you which way to go on your pilot size. Ideally your air screw should be about 1 1/2 to 2 1/2 turns out from seated.

the stock pilot is 32.5 and the stock main is 230, I run a 310 main in my blaster with a toomey pipe and went down I think two sizes on my pilot.
