I did the needle shim with the stock pipes and air box. It has improved performance, as it was running too lean before. I didn't need to purchase a washer, either, as the one that's there can simply be moved down in the stack and works fine.
The OTHER mods (air box and drilling out the plug to get at the mixture screw) should be done only with the new exhaust.
At least, that's the way I read it. Anyone know any different? I have been wrong before and will be again - and it's only 8:30am!
