Oh, boy. Here we go. This has been discussed before. There are several points of view but I think the safest way, I feel, is to first make sure that all the butterfly are closed together and open together. Then use the air screws for fine adjustment. These things really shouldn't be off much to begin with, so be careful. The manual says to use the air screws only. In theory, the butterfly valves should never need to be adjusted. There are somewhat 'hard' wired to a shaft. Unless something has been done to upset that, all adjustments should be at the air screws. That's just my take. I've rebuilt quite a few carb's in the past. They don't generally have air screws so adjustments are made via the bv's. The EFI units on our bikes are supposed to be done with the screws instead. That's my 2 cents, I'm sure you'll get your moneys worth on this topic. (Check the archives!) Brandon
